1 Sewer System Management Plan Goal
Introduction
1.1 Purpose
This Sewer System Management Plan (SSMP) documents plans for properly managing, operating, and maintaining all parts of the City of Thousand Oaks (City)’s sanitary sewer collection system, preventing sanitary sewer overflows (SSOs) from occurring, preventing SSOs that do occur from reaching waterways, and minimizing and mitigating any adverse impacts from SSOs.
1.1.1 SSMP Goals
The goal of this SSMP and SSMP program implementation is to:
• Operate the collection system in safe manner to avoid personal injury and property damage.
• Provide a plan and schedule to properly manage, operate, and maintain all parts of the City’s sanitary sewer collection system.
• Reduce and prevent both dry weather and wet weather SSOs. • Minimize and mitigate the adverse impacts of SSOs that may occur, especially to waterways.
• Prevent public health hazards associated with sewer system management. • Protect the collection system by performing preventive maintenance and extending its useful life.
• Provide adequate capacity to convey peak wet weather wastewater flows. • Comply with all regulatory requirements related to the sewer system.
Achieving these goals will help to reduce and prevent SSOs, as well as mitigate any SSOs that occur. These goals are in alignment with the City’s strategic goals and objectives.
1.2 Regulatory Background
In May, 2006 the California State Water Resources Control Boards (SWRCB) adopted statewide General Waste Discharge Requirements for Sanitary Sewer Systems (SWRCB Order No. 2006 -003), requiring public agencies that own or operate these systems to develop and implement a Sewer System Management Plan (SSMP) and report all sanitary sewer spills to the SWRCB. On December 6, 2022, Water Quality Order No. 2022-0103- DWQ (Sanitary Sewer Systems General Order) was adopted and became effective on June 5, 2023, replacing SWRCB Order No. 2006 -003 and its subseq uent amendment, included as Attachment A1. The WDR prohibits any sanitary sewer overflow that results in a discharge to waters of the United States or that creates a nuisance as defined by City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
California Water Code Section 13050(m). The WDR contains provisions requiring the City to:
• Report all SSOs.
• Take all feasible steps to eliminate SSOs.
• Take all feasible steps to prevent wastewater from discharging from storm drains into flood control channels or waters of the United States by blocking the storm drainage system and removing the wastewater from the storm drains. • Take all feasible steps and necessary remedial actions to control or limit the volume of the SSO, terminate the discharge, and recover as much of the wastewater discharged as possible for proper disposal, including any wash down water.
• Properly manage, operate, and maintain all parts of the sewer system and ensure system operators are adequately trained and possess adequate knowledge, skills and abilities.
• Allocate resources for the operation, maintenance and repair of the sewer system by establishing a proper rate structure , accounting mechanisms, and auditing procedures to ensure an adequate measure of revenue and expenditures. • Provide adequate capacity to convey base flows and peak flows, including flows related to wet weather events. Capacity shall meet or exceed the design criteria as defined in the System Evaluation and Capacity Assurance Plan for all parts of the sanitary sewer system.
• Develop and implement a Sewer System Management Plan and make it available to the State and/or Regional Water Board as well as publicly available. The SSMP must be approved by the governing board at a public meeting. • Conduct periodic audits at least once every three years to evaluate the effectiveness of the SSMP and compliance with SSMP requirements including identification of deficiencies and steps to correct them. • Update the SSMP every 6 years and have the governing board recertify the SSMP when significant updates are made.
On December 6, 2022, SWRCB adopted General Order WQ 2022 -0103-DWQ, and the order became effective on June 5, 2023. General Order WQ 2022-0103-DWQ is included as Attachment A1.
1.2.1 Application for Coverage
The City applied for coverage under the WDR on October 30, 2006, and was assigned a Wastewater Discharger Identification (WDID) for the City’s sanitary sewer system in the State Water Board’s SSO Database . In June 2023, the City submitted documents to maintain coverage under the new General Waste Requirements.

1.4 Sewer System Asset Overview
The City’s sewer service area encompasses approximately 55 square miles and has approximately 3 8,000 connections collecting wastewater from approximately 130,000 people. The sewer service area boundary largely coincides with the boundaries of the City and is not tributary to neighboring systems; however, a small southeastern portion of the City is servi ced by Triunfo Water and Sanitation District. The City provides services to residential, commercial, and industrial customers throughout Dos Vientos, Newbury Park, Thousand Oaks, Westlake Village, and Ventura County unincorporated areas, aligning with the City's boundaries.
The City’s sanitary sewer system, illustrated on Figure 1-1, consists of approximately:
• 415 miles of gravity sewer pipelines
• 38,520 connections
o 36,745 Residential
o 1,334 Commercial
o 430 Commercial Multi-Family (apartments, etc.:)
o 11 Industrial
• 8,300 maintenance holes
• 2.5 miles of force mains
• 2 lift stations
• 11 Siphons
The City does not own, operate nor maintain any portion of the service laterals connecting to the City’s sewer system mainlines. All wastewater collected by the City’s sanitary sewer system is conveyed to the Hill Canyon Treatment Plant for treatment to advanced tertiary levels suitable for unrestricted reuse. The treated effluent is recycled for agricultural irrigation and local landscaping projects (by other agencies) . Any treated effluent not reused is disposed through a permitted surface water outfall t o the North Fork of Arroyo Conejo Creek.
1.4.1 Gravity Sewer System
The City’s gravity sewer system consists of approximately 415 miles of pipelines ranging in diameter from 6 inches to 48 inches. Most of the sewer pipelines are comprised of vitrified clay or polyvinyl chloride (PVC) plastic. Other materials include asbestos cement, ductile iron, and cast iron.
1.4.2 Force Mains
The City has approximately 2.5 miles of force main pipelines ranging in diameter from 3 inches to 42 inches. Most of the force main pipelines are comprised of PVC plastic material. Other materials include reinforced concrete, asbestos cement, and ductile iron.
City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
1.4.3 Lift Stations
The City owns and operates 2 active sewer lift stations, which are Lawrence Drive and Olsen Road Lift Stations.
1.4.4 Siphons
The City currently has 11 known siphons in its collection system. The City has multiple parallel siphons; two siphons running adjacent and parallel to one another. Each parallel pipe is individually designated and counted as a siphon within the wastewater collection system. Investigations are ongoing to identify potential additi onal siphon locations, and updates will be added as new information becomes available.
1.4.5 Storm Water Diversion
The City currently does not divert stormwater to the sewer system. Future studies will explore the possibility of stormwater diversion.
1.4.6 Data Management Systems
The City utilizes several data management systems:
• ArcGIS: Manages sewer pipeline cleaning and manhole inspections, documenting the date, condition, and operator history for each cleaned and inspected asset. • Granite/WinCan: Manages sewer CCTV inspections and reports. Until October 2024, the City utilize d Granite for inspections and stores CCTV asset data internally. As of October 2024, the City uses WinCan web-based cloud storage to store and document CCTV asset data.
• IRIS: IRIS projects the future asset Rehabilitation and Replacement (R&R) needs, highlights high -risk assets, and estimates the appropriate budget required to mitigate the high-risk assets.
1.4.7 Unique Service Boundary Conditions and Challenges • The sewer service area boundary largely coincides with the boundaries of the City, including small sections of Ventura County unincorporated areas, and is not tributary to neighboring systems. However, a small southeastern portion of the City is serviced by Triunfo Water and Sanitation District. All wastewater emergencies occurring outside the City's wastewater service area are included in Triunfo Water and Sanitation District and will be the responsibility of that District; the City of Thousand Oaks will only respond as a mutual-assistance agency when requested and resources are deemed available.

4 Operation and Maintenance Program
This chapter describes the City’s collection system O&M Program, including sewer system mapping, preventative O&M, rehabilitation and replacement, staff training, and inventory of vehicles, equipment, and replacement parts.
4.1 Mapping
The City maintains sewer system mapping in the form of a geographical information system (GIS) database and a Sewer Atlas Map Book.
4.1.1 GIS Database
The City implemented a GIS database that includes quarterly updates, based on as-builts, from the County Assessor’s office of parcel and right -of-way GIS data . The street centerline data originated with TIGER street data and has been refined over the last decade with street name and shape data consistent with recorded documents. The GIS uses the NAD 83 State Plane California V projection.
The comprehensive GIS database contains detailed and up-to-date information on the sanitary sewer collection system network. Sewer facilities include gravity sewer lines, force mains, laterals, valves, and lift stations, with information such as installation date, pipeline diameter, material, length, and interior lining.
All sewer maintenance holes, cleanouts and mainlines were digitized into the GIS database from as-built drawings. Each of the sewer assets on GIS include a hyperlink that connects directly to each corresponding as -built drawing. The vast majority of sewer drawings are at a horizontal scale of 1” = 40’ and georeferenced to property line intersections on the parcel GIS. In addition, these as-built drawings have been scanned and indexed in the City’s Laserfiche system, a content management platform. All as-built numbers are listed as an attribute of all sewer features in the GIS and can be used to access the as-built drawings using the City’s Laserfiche system. Figure 4-1 illustrates the City’s sanitary sewer collection system using GIS.
City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
Figure 4-1. Sanitary Sewer Collection System Geographical Information System Map
City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
City office personnel, engineers, permit processing staff, and planners utilize the GIS database for a variety of purposes, including planning, engineering, permitting, inspecting, and O&M, as summarized below:
Planning: The GIS databases have information on existing sewer mains and piping network, which is used to evaluate the capacity of existing sewer mains and determine the size of proposed improvements.
Engineering: GIS contains attribute data of key sewer main elements (i.e., gravity sewer mains, laterals, maintenance holes, pump stations, force mains) that are essential to sewer improvement design.
Permitting: GIS contains attribute data of key sewer main elements that are essential to permitting for replacement of sewer lines.
Inspection: GIS sewer line attributes can be accessed outside the firewall by Public Works Construction inspectors in the field.
O&M: City field crews have electronic devices with GIS mapping in cleaning trucks to locate and identify sewer system assets. The Wastewater Utilities field crews utilize iPads and iPhones that are connected with the latest GIS data via cellular data on ArcGIS, while the Wastewater Utilities CCTV crew utilize Windows 11 desktop computers and are taken out, rather than synchronized live, once every two years to update with the latest GIS data.
All City office personnel have access to the GIS database through the web browser , and in the event of an emergency, City office personnel can access GIS data through mobile phone. The public currently does not have access to the GIS sewer system database. The City is developing an online map for public homeowners to access as-built drawings.
4.1.2 Reasons and Data Sources for Sewer System Mapping Changes Mapping changes are not frequent; however, when staff identify errors, inconsistencies, or discrepancies with existing data, changes are conducted in a timely manner. As-built drawings are also simultaneously updated. Furthermore, capital improvements to the sewer system trigger the need for mapping updates. The Engineering Division and Capital Improvement Project (CIP) Division provides the Engineering Division GIS team with a list of capital improvement projects to update system mapping. Rehabilitation of sewer system assets are tracked as an attribute of a pipe segment and will not result in any changes to the unique identifier for a pipe segment or to how a pipe is spatially represented in the GIS database.
4.1.3 Updated Map of Sanitary Sewer System
The City has created a public -facing map that includes both the storm drain conveyance and wastewater collection system layers. For any questions or access requests for the updated sanitary sewer system map, please contact the City’s Primary Authorized Representative/Legally Responsible Official.

4.1.4 Sewer Atlas Map Book
The Sewer Atlas Map Book is developed from the GIS databases and includes a map sheet (1.5"=200' scale, 11"x17" paper) for each index area showing the location of force mains, abandoned lines, maintenance holes, cleanouts, valves, network structures (i.e. diversion, inlet, junction, sampling station, treatment plant, and wet well), and lift stations in relation to the City streets and property lines. The Atlas Map Book is secondary source of mapping information, with the GIS mapping being the primary data source for field crews. As a secondary source of mapping data, the Atlas Map Book is infrequently reprinted with the most recent published version printed in 2009. Wastewater Utilities Maintenance values the Atlas Map Book as a backup source for locating sewer infrastructure when electronic databases are not available. The 2009 Atlas Map Book has outdated maintenance hole numbers; therefore, care should be taken to document work activities against updated maintenance hole numbers when documenting work activities.
There are printed copies available within the City Hall and Emergency Operations Center, and if needed, the City has the capability to print individual pages from the Atlas Map Book.

City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
4.3.1 Gravity Sewer Main Cleaning
Wastewater Utilities Maintenance field crews perform hydro flushing to clean the gravity sewer mains using the following cleaning strategies:
• Routine cleaning: Routine cleaning is performed on accessible gravity sewer mains from 6 to 12 inches in diameter at a frequency of 18 to 24 months. To improve response times to customer pipes, the City cleans the sewer system from outward to inward where pipes are older.
• Hot spot “Trouble Areas” cleaning: Hot spot “trouble areas” cleaning is a form of accelerated preventive maintenance and is used on pipe segments with a history of maintenance issues. These p ipelines are assigned more frequent cleaning with a 1-, 3-, or 6-month cleaning cycle.
• Reactive cleaning: Reactive cleaning is performed when Wastewater Utilities Maintenance becomes aware of a sewer overflow or potential blockage affecting sewer system performance resulting. A sewer cleaning crew will respond to customer complaints to investigate the issue and will clean pipe segments suspected of having a blockage to restore service.
Sewer Cleaning Frequency Adjustments
Wastewater Utilities Maintenance is continually evaluating the performance of the sewer system and the causes of maintenance issues. Hydroflushing crews document the type and severity of material encountered when cleaning a pipe segment in their field notes.
This information is then used to determine whether a change to the maintenance cycle is needed.
4.3.2 Chemical Root Control
Pipe segments with pervasive root intrusion issues are chemically treated with a root growth inhibitor. The City uses a contractor to perform root foaming on approximately 19,700 feet of pipelines and some maintenance holes . The Wastewater Utilities Maintenance Supervisor maintains a “root” file containing information on pipe segments with known root issues. If a pipe has light roots at a joint, it will be placed in the folder for potential root foaming.
4.3.3 Inverted Siphon Maintenance
The City has two inverted siphons that are inaccessible to cleaning equipment. The last mile of Unit W trunk line is an inverted siphon. The last 2000 feet of Unit Y trunk line is an inverted siphon. These inverted siphons are operating under pressure and at flow rates well above scouring velocity. Wastewater Utilities Maintenance treats the siphon s with grease removal enzymes approximately every 3 months to prevent grease build-up.
4.3.4 Maintenance Hole Inspection and Cleaning
In addition to sewer cleaning, the City initiated a system-wide maintenance hole inspection program in 2015 and conducted visual inspections of the City’s 8,300 maintenance holes over the past several years. Field crews performing visual inspection measured City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
maintenance hole size and material leading to updates to GIS attribute data. Field crews also documented condition or maintenance issues requiring action resulting in maintenance hole repair and maintenance hole cleaning. The City has completed gathering GIS data for system maintenance holes, and has aligned its updated inspection schedule with the hydro cleaning maintenance cycle, conducting visual maintenance hole assessments every 18 months to 2 years. An internal scoring system, ranging from 5 (excellent condition) to 1 (requiring immediate attention), is used to evaluate maintenance hole conditions. These assessments are documented within an ArcGIS map layer, where field operators use cellular -enabled iPads to inspect and record the condition of each opened maintenance hole.
4.3.5 Canyon Sewer Visual Inspections
Canyon inspections are performed periodically on either a monthly or bi -monthly cycle depending on the canyon. Canyon inspections are also performed after significant rain events. Monthly inspection or bi-monthly inspection activities vary by pipeline and include above grade pipeline s and supports, maintenance holes, laterals, and vents . Monthly canyon inspection locations include the following:
• Unit W W-U67 structure to Hill Canyon Treatment Plan (HCTP) • Lynn Ranch to Unit W (W-U-31 structure)
• Calle Brusca
• Box Canyon
Inspection activities occurring every 2 months vary by infrastructure and include maintenance holes, junction box, access roads, creek crossings, pipe encasement, brush, security doors, structures, valves, and pipe condition. Locations inspected every 2 months include the following:
• Unit X Maintenance holes from California Lutheran University (CLU) to A-37.1 • Unit A A-20 to A37.1
• Unit Y Y-1 to HCTP
• Unit W
• Lower Tunnel Door
• W-2 Structure
• W-J Structure
• Rancho Conejo Lateral
• Calle Salto Lateral
• W-D and W-1 Structures
• Shapell Lateral
• W/F Structure and W-A Structure
City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
Attachment D3 includes the data collection forms used to document the results of canyon visual inspections.
The City has added a tow-behind trailer jetter to perform hydro-cleaning maintenance on accessible 6- to 12-inch gravity sewer mains on an 18- to 24-month schedule. Additionally, a portable 500 -foot cable reel has been added to the new CCTV equipment, with the inspection maintenance pro gram aligned to coincide with easement hydro -cleaning operations.
4.3.6 Flow Meter Maintenance
The City leases 10 permanent flow meters from a flow meter contractor . The flow meter contractor maintains the flow meters and coordinates maintenance access with O&M staff.
City provides traffic control and access to flow meter locations. The flow meter contractor uses cloud-based tools to collect, manage and store flow meter data and to make the data available to City staff for review and analysis.
4.3.7 Easement Access Maintenance
Natural vegetation growth in easements can restrict access to sewer infrastructure.
Wastewater Utilities Maintenance field crews maintain easements to keep sewer infrastructure accessible for maintenance activities, as well as for visual inspection. Work orders are created in the MaintStar MMS and are tracked according to the sewer infrastructure associated with the easement.
4.3.8 Lift Station Maintenance
Wastewater Utilities Maintenance performs lift station preventive maintenance and weekly inspection for two active lift stations. The two lift stations, Olsen Road and Lawrence Drive, are inspected once per week on Mondays. Staff records power, pressure, and flowrate.
Maintenance crews also perform scheduled quarterly maintenance activities at each of the lift stations. The lift station maintenance activities are described below.
Lift Station Site Check List
In addition, staff uses ArcGIS log conditions and maintenance of the lift station s, which includes the following:
• Outside of Building
o Graffiti
o Doors are secured
o Valves are chained and locked
o Chain link fences are secured
o “No Trespassing” signs are posted
o Weeds or debris
• Wet Well
o Level is working

o Well is free of large debris
• Inside Station
o Visible leaks
o All valves are open
o Valves cycle twice
o All switches are on auto
o PLC panel is clear of alarms
o Flush eye wash station
o Check Fire Extinguisher (monthly)
Wet Well Grease Control
Approximately once a month, Wastewater Utilities Maintenance adds degreaser into the wet wells to reduce grease buildup.
Lift Station Quarterly Maintenance
Lift stations are maintenance on a quarterly schedule. In the first and third quarter, the Wastewater Utilities Maintenance crew will perform 6-month maintenance activities and will adjust the pump wear plates. Second and fourth quarter maintenance focuses on changing the pump oil.
Olsen Road Lift Station Generator Checks
A Wastewater Utilities Maintenance crew will run the generator at Olsen Road Lift Station at least every other week to confirm the generator is functioning adequately.
4.3.9 Supervisory Control and Data Acquisition Monitoring The City owns two different SCADA systems, one serving both the water distribution and sewer system and the other serving the Hill Canyon Treatment Plant . The main control center for SCADA is located at the Municipal Service Center for the water distribution and sewer system and is reviewed daily. The Municipal Services Center is open 24 hours a day, 7 days a week. Screens displaying SCADA information are visible in a common area with the administrative personnel. If a SCADA alarm is triggered, administrative staff will be alerted. During after -hours, the alarms will transmit to a standby phone and are answered by standby personnel.
4.3.10 Odor Control
Odor complaints are not frequent; however, if received, the City will investigate, troubleshoot, and clean the line to address the source of the issue. The City will also take the additional measure of corking and sealing the maintenance hole cover. Odor complaint response is documented in MaintStar. If issues are reported via email or phone, administrative staff will document the issue into Maintstar and will contact Wastewater Utilities Maintenance to address the issue.
City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
4.3.11 Underground Service Alerts Utility Locates
Wastewater Utilities Maintenance field crews respond to Underground Service Alerts on an as-needed basis to locate sewer system infrastructure within the work zone of pending construction activities. This reduces the likelihood contractors will damage City sewer pipelines during construction activities.
4.4 Work Management System
The City utilizes various computerized system to management maintenance activities, including the following:
• GIS: The City uses GIS to collect maintenance hole inspection data and document pipelining history.
• MaintStar Maintenance Management System (MMS): This program includes a work management module for documenting work activities , such as customer complaints, work orders, and emergency and preventive maintenance activities against specified wastewater assets. The module allows City staff to computerize its maintenance program and track the maintenance history on individual maintenance holes and pipe segments. The City plans to will integrate GIS into MaintStar through automated nightly synchronization and to include work order information on the map. This program may integrate condition assessment data in the future.
• ArcGIS: Wastewater Utilities Maintenance field crews use this GIS-based, third- party software program to collect field data such as cleaning and field observations. Pipes that require cleaning are color-coded from black to green, with red pipes requiring cleaning and green pipes indicating the pipes have been recently cleaned.
• GraniteNet/WinCan: CCTV vans utilize this software to manage condition of assets. CCTV vans generate work orders for lift stations canyons, and maintenance holes , which documents number of hours , hydrocleaning, maintenance hole inventory, pipe material replacement, or any other issues (i.e., root intrusion). Repairs and CCTV are currently not documented by asset ID unless noted within the notes field of the work order. The City migrated to WinCan, this inspection data is stored on a third-party cloud network and allow ease of access for the organization. CCTV data is uploaded to the cloud once a month, while issues that require additional attention are uploaded in the field via a Starlink internet connection.
• Infrastructure Reinvestment Intelligence System (IRIS) : IRIS is an asset management dashboard that utilizes asset data and performs asset management calculations and analyses. The software is designed to supplement asset record systems (e.g., MMS, GIS) by performing asset management calculations that these systems cannot perform. IRIS projects the future asset Rehabilitation and Replacement (R&R) needs, highlights high-risk assets, estimates the appropriate budget required to mitigate the high-risk assets.
City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
4.5 Condition Assessment and Rehabilitation and
Replacement Planning
The City has processes to identify and prioritize sewer system needs and to identify near- term and long -term actions to address system needs. Processes include inspection, condition assessment and rehabilitation planning processes. The City also performs long- term rehabilitation forecasting to estimate the long-term financial requirements associated with sewer system rehabilitation and renewal.
4.5.1 Gravity Main Closed-Circuit Television Inspection and Rehabilitation Planning
Gravity Main CCTV Inspection
The City has a goal to inspect the sewer system on a 15-year cycle. Wastewater Utilities Maintenance has one CCTV crew performing CCTV inspection and is inspecting approximately 15,000 feet per month and 34 miles annually. The City recently invested in new CCTV inspection equipment. The City documents inspection observations using the National Association of Sewer Service Companies (NASSCO) Pipeline Assessment and certification Program (PACP) standard.
The plan and schedule for CCTV inspection is prioritized based on pipe age, pipe material and maintenance history. The City has inspected approximately 65 percent of the sewer system since the beginning of the latest 15-year inspection cycle, including the middle of town and older portions of the system. In addition to on -going CCTV inspection and condition assessment, the City televises newly constructed pipelines and newly rehabilitated pipelines as the basis for acceptance, providing a baseline CCTV inspection for new and rehabilitated pipelines.
The CCTV inspections conducted from 2019 to October 2024 are stored electronically in GraniteNet software. The most recent CCTV inspections from October 2024 onwards are stored on WinCan webs cloud storage system. Inspections conducted between 2013 and 2019 are stored electronically on an external drive. Prior to that, the CCTV documentation is only accessible via hardcopy files. Some of the CCTV inspections the City is performing are repeat inspections to investigate complaints and support other departments. The City is inspecting pipelines up to 30 inches in diameter.
Gravity Main Rehabilitation Planning
The City is continually evaluating the rehabilitation needs of the gravity sewer system to identify capital improvements. Wastewater Utilities Maintenance collaborates with the Capital Improvements Program Division to conduct CIPP lining projects on a cycle of approximately two years. Over the past decade, the City has been diligent with investing in pipeline rehabilitation and there is currently very little backlog in either the “lining” file or the “root” file. Most capital improvements projects on the se wer system over the last decade have been lining projects to rehabilitate older gravity sewer pipelines.
Lining projects are identified based on recommendations from Wastewater Utilities Maintenance based on review of CCTV inspection observations. The Wastewater Utilities Maintenance Supervisor maintains a “lining” file documenting the pipe segments that are City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
candidates for lining. The pipe segments in the lining folder are evaluated periodically to create a lining project. The decision criteria for selecting pipe segments for repair, rehabilitation or replacement includes:
• Severe structural defects such as collapse, missing wall, and broken pipe. This is not very common.
• Significant sags
• Offset joints
• Fractures
• Pervasive root intrusion
The Wastewater Utilities Maintenance Supervisor also maintains a separate root intrusion file documenting pipe segments with known root intrusion issues. These pipe segments are evaluated at the same time and possibly included in a lining project.
If a pipe segment has a significant defect and it is localized, the City may decide to perform a localized point repair. Repair projects are categorized into three tiers:
• Small Projects – In House Repair
• Medium – On Call Contractors (if requires trenching) may do lining using this approach.
• Large Projects over $60,000 to $75,000 are bid out
4.5.2 Maintenance Hole Rehabilitation
Wastewater Utilities Maintenance field crews recently completed a multi -year inspection program of the City’s 8,300 maintenance holes. Field crews identified maintenance holes with repair and rehabilitation needs . These maintenance holes repair and rehabilitation needs are either addressed by in-house crews, added to lining projects , or are grouped into separate maintenance hole rehabilitation projects.
4.5.3 Force Main Inspection and Rehabilitation
The City’s two force mains were recently rehabilitated with cured-in-place pipe (CIPP) lining and are in good condition.
4.5.4 Lift Station Inspection and Improvements
In addition to weekly inspections and quarterly maintenance activities, Wastewater Utilities Maintenance will team with Capital Improvements Program Division staff to perform lift station condition assessment every two years to identi fy lift station capital investment needs. The Capital Improvements Program Division gets involved with larger projects related to the lift station. The CIP Division initiates CIP projects every 2 years with sewer, electrical, or instrumentation crew input to identify the needed improvements. This aligns with the City’s 2-year Capital Improvement budget cycle. The lift station condition needs are identified by a multi-disciplinary team consisting of Wastewater Utilities Maintenance crew providing expertise in mechanical systems, while an electrical and instrumentation crew identify the needs of the electrical and instrumentation systems. Capital City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
Improvements Program Division staff provid e expertise with lift station structural components. Currently from a structural perspective, both lift stations are reported to be in good condition.
4.5.5 Financial Planning for Sewer System Needs
In addition to system-wide inspection and condition assessment, the City utilizes IRIS software to model the long-term investment needs of the sewer system. IRIS is an a sset management software program that models the lifecycle costs associated with sewer system assets based on the age and expected useful life of pipeline and lift station assets.
The model forecasts the long-term investment required to address rehabilitation and replacement needs. The final result is a Water and Wastewater Asset Management Plan with forecast outputs that inform financial rate setting and support the City with justifying investment in sewer system rehabilitation and replacement. The most recent Water and Wastewater Asset Management Plan can be found online at:
toaks.gov/corecode/storage/uber_resource/uploaded_pdfs/Thousand Oaks AMP 2017 - Dec 2017 Update_1739494457.pdf
The City also maintains an internal 10-year capital improvement plan and includes a line item for sewer system rehabilitation every 2 years.
4.6 Training
General Order , Spill Emergency Response Plan , Skilled Estimation , and CIWQS Training
The City provides annual training for staff on the requirements of General Order WQ 2022- 0103. Each September, the Utilities Maintenance Supervisor conducts training on the City’s Spill Emergency Response Plan procedures and the requirements of General Order WQ 2022 -0103. This training includes practice drill s and the skilled estimation of spill volume, as outlined in the City’s Emergency Response Plan Attachment F1. Additionally, the Utilities Maintenance Supervisor coordinates regular training on CIWQS re porting procedures for staff responsible for data submission. This includes reviewing spill reports with the City’s other LROs and Data Submitters prior to the Utilities Maintenance Supervisor's initial reports and certification of spill reports.
The City provides safety and training programs on a regular basis for staff in sewer collection system operations, maintenance, and monitoring. For instance, Job Safety Analysis reviews are completed once a month on various equipment, such as combination hydroflushing vacuum units (i.e., Vactor and Va c-Con) or shoring. Key safety aspects reviewed include required personal protective equipment, sequence of basic job steps, potential accidents or hazards, additional safety job procedure. The reviews also include descriptive operating procedures and precautions for proper usage. The Job Safety Analysis calendar is included as Attachment D4. Project specifications require contractor certifications or training to complete work.
Onboarding and Training Rotations
New Wastewater Utilities Maintenance staff are onboarded through training rotations every two weeks to become familiar with how to conduct canyon inspections and how to operate City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
each key piece of equipment, such as combination hydroflushing vacuum units (i.e., Vactor truck and Vac-Con truck) and CCTV trucks. The trainings address the skills necessary to perform proper operations and maintenance, to provide timely and effective emergency response, and to incorporate recognized safety practices.
According to Figure 2-2, either a Water Utilities Maintenance or Wastewater Utilities Maintenance crew member will be assigned to the Duty response and respond to sanitary sewer overflow calls during after-hours. Therefore, new Wastewater Utilities Maintenance staff are cross trained in water distribution system operations and maintenance activities for about 2 to 3 months, while new Water Utilities Maintenance staff are cross trained in sewer system operations and maintenance activities.
Certification
Certification in Collection System Maintenance is preferred, but not required to work in Wastewater Utilities Maintenance. Even so, several crews members have attained Collection System Maintenance certification through the California Water Environment Association’s certification program (CWEA). Both Water and Wastewater Utilities Maintenance Workers share the same job title and must hold a Distribution Grade 1 certification from the State Water Resources Control Board’s Drinking Water Operator Certification Program (DWOCP). Several Water Utilities Maintenance staff also have CWEA Collection System Maintenance certification.
All crew members in either Water Utilities Maintenance or Wastewater Utilities Maintenance are required to have a Class B Driver’s License , although most field employees have a Class A Driver’s License.
On-Going Training
The City provides on-going training for staff through special classes or seminars, in-house training, conferences, training by equipment vendors, and annual performance reviews.
Regarding conferences, t he City sends staff to the Tri -State conference, local CWEA annual conference, and Water Environment Federation’s Technical Exhibition and Conference for training , when appropriate. In -house training includes training such as wastewater math, forklift operation, and confined space.
4.7 Vehicles, Equipment, and Parts Inventory
The City owns and maintains a variety of vehicles and equipment used for operations and maintenance of the sewer collection system and emergency response. The City utilizes the Fleet Maintenance shop at the Municipal Service Center for any issues and for regular equipment maintenance. Combination hydroflushing and vacuum units and CCTV vans are replaced approximately every 10 years. If cameras cannot be fixed in-house, cameras are sent to Plumber’s Depot for repair at CUES.
4.7.1 Major Vehicles and Equipment
The following list summarizes the City’s major vehicles and equipment at the Municipal Center:
• Combination hydroflusher/vacuum units (2)

5 Design and Performance Provisions
This chapter describes the design, construction, and inspection standards the City uses to ensure sewer system infrastructure is properly designed and constructed.
5.1 Regulatory Requirements
The SWRCB Order No. 2022-0103-DWQ, outlines the Plan must include the following items as appropriate and applicable to the Enrollee’s system:
a. Updated design criteria, and construction standards and specifications, for the construction, installation, repair, and rehabilitation of existing and proposed system infrastructure components, including but not limited to pipelines, pump stations, and oth er system appurtenances. If existing design criteria and construction standards are deficient to address the necessary component -specific hydraulic capacity as specified in section 8 (System Evaluation, Capacity Assurance and Capital Improvements) of this Attachment, the procedures must include component-specific evaluation of the design criteria. Procedures and standards for inspecting and testing the installation of new sewers, pumps, and other appurtenances and for rehabilitation and repair projects. b. Procedures, and standards for the inspection and testing of newly constructed, newly installed, repaired, and rehabilitated system pipelines, pumps, and other equipment and appurtenances.
5.2 Design and Construction Standards and Specifications The City engineers, developers, and consultants currently utilize a set of Wastewater Design and Construction Standards as the basis for design and construction of sanitary sewer collection systems. The Wastewater Design and Construction Standards, approved and adopted by City Council in 1979 (revised in 1980), are accessible on the City’s webpage at:
Searchable 1979 WW Standards_661.pdf
The Wastewater Design and Construction Standards provide the design criteria, construction requirements, and construction standards for new sewer system infrastructure as well as standards for inspecting and testing the installation of new sewer system infrastructure. The City is updating the current Wastewater Design and Construction Standards, and anticipates completed and certified updates by the next SSMP Audit Period of 5/02/2027.
5.2.1 New Sanitary Sewer Infrastructure
The Wastewater Design and Construction Standards provide a comprehensive set of standards for the major component of new sewer system infras tructure including sewer pipelines, maintenance holes, cleanouts, laterals, lift stations, and force mains. Design and construction specifications for air release valves are prepared as part of the corresponding sewer system capital improvement project and are subject to review and approval by City staff.
City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
5.2.2 Rehabilitated and Repaired Sewer System Infrastructure The City is largely built out and most of the capital improvement efforts are rehabilitation and repair, rather than installation of new pipelines. Standards for design and construction are prepared individually for specific sewer system capital improvement projects. Sewer pipeline rehabilitation specifications are developed by consultants in collaboration with City engineering staff . Over time, City staff have assembled a library of sewer pipeline rehabilitation specifications from various projects. This is necessary due to the constant flux in pipeline rehabilitation technologies and tools available in the industry.
5.2.3 Design Review and Approval
Standards are enforced through a permitting process to ensure design and construction is adequately performed. City engineering staff perform plan checks to ensure the design drawings are calling out and referencing the standards. The City performs plan check at different stages of the design process. Typically, plan checks are performed at the 30%, 60%, and 90% design phase on projects.
5.3 Inspection and Testing of New and Rehabilitated Sewer Infrastructure
New and rehabilitated sewer infrastructure require inspection and testing under specific procedures and standards. The City requires contractors to maintain a performance bond for 10 years to address latent construction defects on capital improvement projects.
5.3.1 Inspection and Testing Procedures and Standards
The City performs various types of inspection and testing during and after construction to ensure sewer system infrastructure is built properly before accepting new or rehabilitated infrastructure into the sewer system. The City’s construction inspector and capital improvement Project Engineer are responsible for sewer infrastructure acceptance and approval of capital improvements or new d evelopment. Table 5-1 lists the various inspection and testing procedures the City employs to ensure sewer system infrastructure is properly constructed.
5.3.2 Inspection and Testing Resources
City staff evaluate upcoming capital improvement projects to determine the project management and construction inspection workload requirements and assign project management and construction inspection duties to either in-house staff or to a third party, depending on the size of the project and the workload demands.
Regardless of who performs project management and construction inspection duties, the resources assigned to perform these duties are performed in conformance with plans, contract documents, and City standards.

7 Sewer Pipe Blockage Program
This chapter describes the City’s FOG control program. Oil and grease contributions to the City's wastewater collection system have been regulated by the City Municipal Code since the late 1970s, mandating installation and maintenance provisions for grease control devices (i.e., grease trap or grease interceptor) to alleviate grease discharged into the sanitary sewer collection system in over 400 food service establishments (FSE) and auto service repairs.
The Public Works and Community Development (Building Division) Departments have worked closely to ensure that appropriate fixtures, drains, and mop sinks associated with commercial kitchen and restaurant clean -up facilities are plumbed through these oil and grease separation devices. A new ordinance is in development to establish clarity on which establishments require a grease trap and guidance for determining the appropriate type, flow, operations, and size for grease removal device. The Environmental Compliance group, within the Public Works Department, has worked closely with the Collection System Maintenance group. This effort is conducted to identify hotspot areas, isolate problematic sources, conduct stepped-up inspections, control rags and debris, and require increase pumping and cleaning of traps and interceptors as needed. Where specific sources cannot be isolated, more routine cleaning and jetting of the collection system has been initiated.
7.1 Regulatory Requirements
The SWRCB General Order 2022-0103-DWQ, Attachment D section 7 Sewer Pipe Blockage Control Program requires the City to include procedures for the evaluation of the Enrollee’s service area to determine whether a sewer pipe blockage control program is needed to control fats, oils, grease, rags and debris. If the Enrollee determines that a program is not needed, the Enrollee shall provide justification in its Plan for why a program is not needed.
The procedures must include, at minimum:
• An implementation plan and schedule for a public education and outreach program that promotes proper disposal of pipe-blocking substances; • A plan and schedule for the disposal of pipe-blocking substances generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of substances generated within a sanitary sewer system service area; • The legal authority to prohibit discharges to the system and identify measures to prevent spills and blockages;
• Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, best management practices requirements, recordkeeping and reporting requirements; • Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the fats, oils, and grease ordinance;
City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
• An identification of sanitary sewer system sections subject to fats, oils, and grease blockages and establishment of a cleaning schedule for each section; and • Implementation of source control measures for all sources of fats, oils, and grease reaching the sanitary sewer system for each section identified above.
7.2 Fats, Oils, and Grease Public Outreach Program
The City focuses p ublic outreach education towards residential customers through sustainability blogs on the public website and towards the commercial kitchen and restaurant business sector s through inspections . Inspectors verbally educate proper disposal of FOG concurrently with facility inspections, such as during the review of pretreatment device s at auto repair services , inspection of restaurants for stormwater compliance with the MS4 permit, or inspection of school cafeterias. Sustainability blogs and social media are used periodically throughout the year to educate the Public with FOG control and proper FOG disposal, including blogs on FOG disposal sites. The outreach program is led by the Sustainability Division under the guidance of the Strategic Communication and Public Affairs department , and the Utilities Maintenance Supervisor works with the Sustainability Division to schedule additional outreach topics to be added to the blog calendar periodically. For example, during the holiday season, the City publishes a blog on proper grease disposal and cooking oil management. These blogs educate residents on best disposal practices and provide information on the City's Household Hazardous Waste Facility as an acceptable disposal site. Below is a link to the City’s Sustainability Blog:
Sustainability Blog | Thousand Oaks, CA
7.3 Plan and Schedule for Disposal of Fats, Oils, and
Grease
The City supports proper disposal of fats, oils and grease generated within the City limits either by providing residential customers with a means for proper disposal and by requiring and enforcing proper disposal by commercial establishments.
7.3.1 Residential FOG Disposal
Among the services the City provides to residents, a Household Hazardous Waste Day (one day per month) is conducted for disposal of accumulations of household grease and cooking oil. The City also has an agreement with the neighboring city of Camarillo for residents to use their facilities for d isposal on two additional days per month. Residents may also allow small accumulations of grease to congeal in a container and dispose of grease waste through solid waste/curbside collection and disposal to a landfill.
Acceptable Disposal Facilities in Service Area:
• Household Hazardous Waste 2010 Conejo Center Drive, Newbury Road , Ca 91320. (800) 356-8570
City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
7.3.2 Commercial and Industrial FOG Disposal
Regarding the commercial and industrial community, the Municipal Code identifies thresholds for maintenance required for the operators of interceptors and traps based on the accumulation of both settled solids and oil and grease. According to Section 10.1-6.04, Control of Regulated Wastes, these units are required to be pumped out if at least 25 percent accumulated with grease. The new Ordinance in development will state the need for certified contract pumper to pump the grease. Although there is no mandated cleaning frequency, the grease interceptors and traps are typically checked by the establishments on a regular basis, either quarterly or biannually. Removed material is either hauled to the City’s Hill Canyon Treatment Plant or legally disposed of outside of the city limits. Small grease traps under the sink are typically cleaned weekly.
There are three inspectors under the Public Works Environmental Compliance Group that delegate the facility inspections. The stormwater permit mandates inspectors to alternate inspecting FSEs and auto service repairs annually (1 year inspect FSE, next year inspect auto service repairs), in which the inspectors use this session to check the manifest for record of cleaning.
7.4 Fats, Oils, and Grease Program Legal Authorities
Fats, oils and grease source control program legal authori ties can be found in the Municipal Code in Title 10, Article 6 Industrial Waste Regulation . Please refer to section
3.2 Legal Authorities for a link to the Municipal Codes and consult Table 7-1. Municipal Code and Design and Construction Standards References to reference the City’s legal authority to prohibit discharges to the wastewater collection system.
7.4.1 Authority to Inspect and Enforce Fats, Oils, and Grease Program Requirements
The authority to inspect and enforce is contained in Municipal Code Section 10-1.604 - Control of Regulated Wastes, and Municipal Code Section 10 -1.605 - Industrial Wastewater Monitoring and Reporting, of the Municipal Code. The Code provide s two avenues to pursue compliance. The first is through capacity inhibition and maintenance with regards to grease removal devices. The second avenue is through monitoring by performing an oil and grease concentration analysis.
The City enforces FOG requirements by issuing a warning if the grease removal device is improperly maintained. If conditions persist through subsequent inspections, a fine is issued to the owner and/or user of the property.
The City employs three full time Environmental Compliance Inspectors to inspect facilities and enforce the regulations as well as document and correct compliance issues of the existing oil and grease discharge community.
City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
7.5 Fats, Oils, and Grease Program Requirements
7.5.1 Requirements to Install Grease Control Devices
The requirement to install , maintain, and keep records of grease control devices is specified in Section 10 -1.604, Control of Regulated Wastes, of the Municipal Code. The Code relies on the discretion of the establishment Director to identify that the property produces enough grease to warrant a grease control device. On a case-by-case basis, the City Engineering Department assists in the determination by evaluating the property and the menu. The establishments are responsible to report to the City if menus change.
7.5.2 Design Standards for Grease Control Devices
City code requires a restaurant, or other establishment , that discharges wastewater containing grease to install and regularly maintain an interceptor to prevent excessive discharges of grease into the waste-water system. The type and size shall be as regulated by the building provisions of the Municipal Code or as required by the Public Works Director.
In practice, the Building Division will review building permits to determine whether a permit application for a new or existing establishment triggers the requirement for a grease trap or interceptor. All commercial kitchens requiring a hydromechanical grease interceptor or gravity grease interceptor are required to size the device according to the most recent adopted California Plumbing Code. Grease traps are installed inside the restaurant and can have capacity ranging from 50 to as high as 250 gallons, while grease interceptors are installed outdoors with a minimum capacity of 750 gallons to as high as 1,200 or 1,500 gallons. The maximum size for a grease interceptor is 3,000 gallons.
7.5.3 Maintenance Requirements for Grease Control Devices Each commercial kitchen with a grease control device is required to employ an appropriate service or procedures for periodic collection of accumulated grease from any grease control device. Inspectors from Public Works Environmental Compliance will review maintenance records and compliance with the 25% rule. The 25% rule requires grease control devices to have no more than 25% of the volume of the device consumed by accumulated grease. Commercial kitchens are not allowed to introduce grease into any sewer lateral, public sewer, storm drain, or public right-of-way. FSEs are required to supply documentation, such as invoices, to prove compliance with grease control device maintenance requirements.
7.5.4 Record Keeping and Reporting Requirements
Each commercial kitchen with a grease control device is required to keep 2 years of records of cleaning, maintenance, and grease removal. A separate maintenance log must be maintained for each grease control device and posted in the immediate vicinity of each device. Maintenance logs will include the following information: grease control device location and volume; maintenance dates; volume removed (gallons); disposal methods; and name of person performing maintenance; and, if the person is not employed by the City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
commercial kitchen, the name, address, and phone number of the person or company performing the maintenance activities.
7.6 Fats, Oils, and Grease Control Program Resources
The City has assigned FOG program inspection and enforcement duties to three Environmental Compliance Inspectors in the Public Works Department who perform compliance inspection s to enforce auto, stormwater, industrial and grease control requirements in the Municipal Code. This level of staffing enables the City to accomplish an inspection of each food service establishment kitchen once approximately every two years. When applicable, follow -up inspection s are scheduled and conducted for progressive enforcement.
7.7 Sewer Pipe Blockage Maintenance Program
Identification of pipe segments prone to blockage and the cause of the blockages is based on review of available information potentially including one or more of the following sources: blockage history, CCTV inspection data, FOG investigations, and FOG source control inspections of FSEs. Pipes prone to blocka ges can be addressed through more frequent cleaning and targeted outreach and/or inspection of upstream dischargers. Areas known to be a problem have been put into monthly, quarterly, or semiannual cleaning frequencies. This program is described in detail in Chapter 4, Operations and Maintenance Program.
Wastewater Utilities Maintenance has identified sections of the sewer system subject to grease blockages and established a cleaning maintenance schedule for each section.
When a grease-related SSO occurs, Wastewater Utilities Maintenance will monitor the site quarterly to determine whether grease accumulation in the pipe segment is a pervasive issue. If grease build-up continues to be an issue, Wastewater Utilities Maintenance will place the pipe segment on a 1, 3, or 6-month trouble spot cleaning cycle depending on the severity of the grease accumulation detected. If nearby food service establishments are suspected, Environmental Compliance Inspectors will perform an inspection of the nearby FSEs upstream of the blockage, including the review of maintenance records for grease control devices. If a private residence is suspected as the source of the grease discharge, Wastewater Utilities Maintenance will notify and educate the residence on practices they can employ to prevent the grease discharges.
The City is not currently experiencing any issues with rag accumulation or debris blockages. If excessive rags are found in the sewer pipes, the Collection System Maintenance staff will notify the Environmental Compliance department as needed.
Environmental Compliance staff will then investigate and engage with businesses to ensure proper rag and wipe disposal . A rag or debris control program for sewer pipes is not needed currently. The Legally Responsible Official will assess the need based on Sanitary Sewer Overflows, hydro cleaning maintenance, and field observations by Collection System staff.
City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
7.8 Preventive and Source Control Measures
The City uses a combination of preventive and source control measures to address FOG discharges to the sewer system, including the following:
FSE inspections : This involves source control inspections of FSEs to determine compliance with FOG ordinance requirements.
Trouble Spot Program: This involves scheduled recurrent cleaning of known grease problem areas on frequencies of 1, 3, or 6 months.
Sewer Main and Maintenance Hole Inspection Program: This involves the visual and/or televised inspection of mains and maintenance holes.
Sewer main replacement : This involves the repair, replacement, or rehabilitation of impacted sewers to improve sewer flow velocities. An outside contractor is engaged if the line can be repaired from maintenance hole to maintenance hole.

8 System Evaluation, Capacity Assurance
Plan, and Capital Improvements
This chapter describes the City’s System Evaluation, Capacity Assurance Plan , and Capital Improvements . The System Evaluation and Capacity Assurance Plan utilizes information from the most current wastewater master plan, the City of Thousand Oaks Wastewater Interceptor Master Plan Final Report (Master Plan) from July 2002.
The Master Plan can be found online at:
toaks.gov/corecode/storage/uber_resource/uploaded_pdfs/Wastewater Master Plan July 2002 ocr (1)_1739494533.pdf
The SWRCB Order No. 2022-0103-DWQ, Attachment D System Evaluation, Capacity Assurance and Capital Improvements requires that the City prepare and implement the following procedures and activities:
System Evaluation, Capacity Assurance and Capital Improvements The Plan must include procedures and activities for:
• Routine evaluation and assessment of system conditions; • Capacity assessment and design criteria;
• Prioritization of corrective actions; and
• A capital improvement plan.

• Identify system assets vulnerable to direct and indirect impacts of climate change, including but not limited to sea level rise; flooding and/or erosion due to increased storm volumes, frequency, and/or intensity; wildfires; and increased power disruptions.
Capacity Assessment and Design Criteria
The Plan must include procedures to identify system components that are experiencing or contributing to spills caused by hydraulic deficiency and/or limited capacity, including procedures to identify the appropriate hydraulic capacity of key system elements for:
• Dry-weather peak flow conditions that cause or contributes to spill events; • The appropriate design storm(s) or wet weather events that causes or contributes to spill events;
• The capacity of key system components; and
• Identify the major sources that contribute to the peak flows associated with sewer spills.
The capacity assessment must consider:
• Data from existing system condition assessments, system inspections, system audits, spill history, and other available information; • Capacity of flood-prone systems subject to increased infiltration and inflow, under normal local and regional storm conditions;
• Capacity of systems subject to increased infiltration and inflow due to larger and/or higher-intensity storm events as a result of climate change; • Increases of erosive forces in canyons and streams near underground and aboveground system components due to larger and/or higher -intensity storm events;
• Capacity of major system elements to accommodate dry weather peak flow conditions, and updated design storm and wet weather events; and • Necessary redundancy in pumping and storage capacities.
Prioritization of Corrective Action
The findings of the condition assessments and capacity assessments must be used to prioritize corrective actions. Prioritization must consider the severity of the consequences of potential spills.
Capital Improvement Plan
The capital improvement plan must include the following items:
• Project schedules including completion dates for all portions of the capital improvement program;
City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
• Internal and external project funding sources for each project; and • Joint coordination between operation and maintenance staff, and engineering staff/consultants during planning, design, and construction of capital improvement projects; and Interagency coordination with other impacted utility agencies.
8.1 System Evaluation and Condition Assessment
The City’s 20 02 Wastewater Interceptor Master Plan was prepared to provide a comprehensive assessment of the structural condition and hydraulic capacity of the City’s interceptor sewer system and a phased 10 -year plan for capital improvements. The Wastewater Interceptor Master Plan analyzed the City’s wastewater service area, which largely coincides with the boundaries of the City. The Wastewater Interceptor Master Plan is developed to reflect the ultimate buildout of the City collection system.
The projected near-term and long-term average dry weather flows and peak wet weather flow, as estimated from the 2002 Wastewater Interceptor Master Plan and 2020 Treatment Plant Master Plan, are presented in Table 8-1. The current average dry weather flow in the system (total of flows to Hill Canyon Treatment Plant) is approximately 9 million gallons per day (MGD).

1. Peak wet weather flows are estimated using average dry weather flows from the 2020 Treatment Plant Master Plan and wet weather peaking factor of 2.5 per the 2002 Wastewater Interceptor Master Plan.
The City currently monitors flows at 10 flow monitoring locations throughout the collection system, including influent flows to the Hill Canyon Treatment Plant. The City conducted a treatment plant analysis as part of the 2020 Hill Canyon Treatment Plan Master Plan, which provided an updated projection of City wastewater flows into the plant.
Recent project -specific sewer studies evaluated the sewer collection system capacity against projected flows in the 2002 Interceptor Master Plan as well as the existing flow meter data. While the 2002 Interceptor Master Plan did not identify capacity deficiencies within the system at the time, several projects were identified to address potential capacity deficiencies until buildout conditions. The City has since implemented nearly all the capacity projects recommended in the 2002 Interceptor Master Plan and continues to monitor the system for flows and SSOs using field inspections, flow monitoring data, and influent data for the Hill Canyon Treatment Plant. The City is currently conducting its 2025 Collection System Master Plan and will update the Sewer System Management Plan based on its findings.
City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
8.1.1 System Evaluation Practices
As outlined in Section 4.3.1, Gravity Main Closed Circuit Television and Rehabilitation Planning of this SSMP, the City utilizes CCTV inspection results and the PACP rating system to assess pipeline conditions and plan future capital repair and replacement projects. The City follows a 15 -year CCTV inspection cycle, assessing approximately 34 miles of pipeline annually, which accounts for about 8% of the sanitary sewer system. The frequency of CCTV inspections is currently based on available equipment and in ternal staffing; however, the City is evaluating the possibility of increasing inspection frequency as part of the 2025 Collection System Master Plan. For manhole inspections, the City has aligned its inspection schedule with the hydro cleaning maintenance cycle, conducting assessments every 18 months to 2 years. An internal scoring system, ranging from 5 (excellent condition) to 1 (requiring immediate attention), is used to evaluate manhole conditions. These assessments are documented within an ArcGIS map layer, where field operators use cellular-enabled iPads to inspect and record the condition of each open ed manhole. This program was launched in 2024, and any manholes identified with deficiencies are also recorded in MaintStar work orders. The Utilities Maintenance Supervisor maintains an Excel spreadsheet tracking manholes in need of rehabilitation and collaborates with the Engineering Division to schedule Capital Improvement Projects.
8.1.2 Condition Assessment Vulnerable Areas
The City has identified pipelines and facilities with a high level of environmental risk, particularly in areas near surface waters such as the Arroyo Conejo natural waterway. This SSMP includes details on condition assessments in Section 4.3.5 Canyon Sewer Visual Inspections, which outlines maintenance inspections of high-risk locations vulnerable to erosion, collapse, and proximity to surface waters.
In addition to these inspections, six of the ten flow meters are located in vulnerable areas, monitoring system conditions through cloud -based software with alarm set points that notify the Utilities Maintenance Supervisor and Utilities Maintenance Crew Leaders via email. For pipelines on steep terrain, as identified in Section 4.3.5 Canyon Sewer Visual Inspections, in -house drone inspections are coordinated to enhance monitoring and assessment effort s along with the monthly, bi -monthly, after rain event, a nd post- earthquake inspections.
Areas that hold a high level of environmental consequences and/or near surface waters have been identified by the Utilities Maintenance Supervisor. To support this, the City’s GIS team is developing an ArcGIS app that will allow the Utilities Maintenance Supervisor to define color coded boundaries of identified areas, making them identifiable for the maintenance ArcGIS applications and City staff.
8.2 Design Criteria
Design criteria for evaluating the capacity of the existing sewer system and new facilities were developed as part of the 2002 Wastewater Interceptor Master Plan, City Wastewater Design and Construction Standards, and subsequent project-specific sewer studies. For gravity sewers, the criteria are based on maximum flow depth under design peak wet weather flow, expressed as the ratio of flow depth to pipe diameter. These criteria are presented in Table 8-2.
City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update

The City’s Wastewater Design and Construction Standards also includes criteria for design of sewer facilities. These criteria are primarily intended for design and construction of new sewer facilities to serve new development and include average sewage generation rates based on land use type, peaking factors ba sed on population (for residential developments), or a specified peaking factor equation, and criteria for minimum sewer velocities and slopes. The sewage generation rates are shown in Table 8-3 and are consistent with those used in the 2002 Wastewater Interceptor Master Plan and project sewer studies . Minimum slope criteria from the Wastewater Design and Construction Standards are also presented in Table 8-4.

8.3 Capacity Enhancement Measures
The 2002 Wastewater Interceptor Master Plan recommended eight capacity-related improvement projects to accommodate future development, as shown in Error! Reference source not found. . Projects identified to address short-term capacity deficiencies were proposed to be constructed within 2 years of the Wastewater Interceptor Master Plan , while projects identified to address medium or long-term capacity deficiencies would be constructed within 5 to 10 years , depending on timing of need. The capacity-enhancing projects identified in the 2002 Wastewater Interceptor Master Plan have almost all been implemented by the City since 2002, with the exception of Unit E Interceptor at Ventu Park Road. The addition of the Lawrence Drive L ift Station has reduce d flow to Unit E by pumping some of Newbury Park down Lawrence Drive . However, in the event of pump failures or power outages, the wet well head will push flow back under the freeway to Unit E as part of its contingency plan . The City plans to further investigate capacity at this location and is currently gathering flow data as part of the 2025 Wastewater Collection System Master Plan while assessing the 33” pipeline. Additionally, a planned Capital Improvement Project (Table 8-5.1 Capital Improvement Schedule-MI2515) will include a CCTV inspection to evaluate the condition of the pipe segments under Ventu Park Road.

8.4 Prioritization of Corrective Action
The above -described design criteria and capacity assessments are used to prioritize corrective actions. The likely severity of potential spills (e.g., potential volume, proximity to surface waters) is a factor considered in the prioritization process. Spill events that occur are prioritized with both short- and long-term solutions as needed to avoid repeat incidents.
The City employs several additional methods to prioritize corrective actions, including:
• Age of Infrastructure
• Wastewater Collection Master Plan Recommendations
• IRIS Asset Management Software
• CCTV inspection Data and NASSCO Scoring
• Feedback from Operations and Maintenance
• Repeated and Ongoing Issues, Roots, Grease, and Pipe Defects The City has ongoing implement rehabilitation and corrective action measures as outlined in the Operation and Maintenance program of this SSMP document. See Section 4.5 Condition Assessment and Rehabilitation and Replacement Planning, for additional guidance on prioritizing corrective actions and rehabilitation efforts.
8.5 Capital Improvement Plan
As noted above, the City is undergoing a major update of its Wastewater Interceptor Master Plan in 202 5 and will use the results of that study to update its capacity CIP schedule and budget. The City’s FY2024-2025 CIP includes the following capacity-related projects:
• MI2589 - Collection System Master Plan Update (FY 2024/2025) The City will also be conducting a flow monitoring program to obtain data for use in the Wastewater Collection System Master Plan update, although the work may be conducted in conjunction with the Master Plan Update. After completion of the updated Master Plan, the schedule for additional capacity improvements will be updated and incorporated into the City’s CIP.
The City continuously evaluates its Capital Improvement Plan through joint coordination between the Engineering Division, Operations and Maintenance, and external consultants during the planning, design, construction, and rehabilitation phases of Capital Improvement Projects. Regular meetings are conducted during the planning phases, with weekly progress meetings coordinated between external consultants, Operations and Maintenance, and the Engineering Division during the project phases.
Part of the Capital Improvement Plan includes ongoing CIPP rehabilitation projects. The Wastewater Utilities Maintenance Supervisor maintains a “lining” file documenting the pipe segments that are candidates for lining. The pipe segments in the lining folder are evaluated periodically to create a lining project that is shared with the City engineers during the Capital Improvement budget cycles. As needed, the City coordinates with other utility City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
agencies that City of Thousand Oaks Capital Improvement Plan Projects impact during all stages of the projects.
The City's Capital Improvement budget cycle occurs every two years, with long -term projects planned over a five -year period. Every two years, the Capital Improvement schedule and projects are updated through a coordinated effort between Engineering, Finance, and Operations. Completed projects are removed from future planning. Existing projects are revised and adjusted, and new projects are added as needed. The approved budget covers the first two years, while the following three years are part of the proposed future budget. These projects are funded through the Wastewater Enterprise Fund. Table 8-6 shows the proposed CIP budget currently in progress, which is scheduled for Council adoption prior to the end of June 2025. These projects and schedules are subject to change prior to adoption, but once adopted, they will be authorized for the next two years.

2025 Sewer System Management Plan Update
9 Monitoring, Measurement, and Program
Modifications
This chapter describes the City’s approach to maintaining, monitoring , and updating information relevant to evaluating the effectiveness of this SSMP.
9.1 Regulatory Requirements
The SWRCB Order WQ 2022 -0103-DWQ, Attachment D Section 9 of the Plan must include an Adaptive Management section that addresses Plan -implementation effectiveness and the steps for necessary Plan improvement, including:
• Maintaining relevant information, including audit findings, to establish and prioritize appropriate Plan activities;
• Monitoring the implementation and measuring the effectiveness of each Plan Element;
• Assessing the success of the preventive operation and maintenance activities; • Updating Plan procedures and activities, as appropriate, based on results of monitoring and performance evaluations; and
• Identifying and illustrating spill trends, including spill frequency, locations and estimated volumes.
9.2 Maintenance of Information Used to Prioritize Activities The City has multiple databases for tracking sewer system asset attributes, maintenance activities, and sewer pipeline inspection.
GIS: The City maintains information of pipelines, such as installation date, size, depth, length, material, and location, through as -built drawings and GIS. Maintenance hole inspections and pipeline linings are logged into GIS. Refer to Section 4.1.1 for details regarding GIS database.
MaintStar and ArcGIS: Sewer pipeline maintenance activities are tracked using a combination of MaintStar and ArcGIS. MaintStar is the data repository for sewer pipeline maintenance data while ArcGIS provides the means to collect maintenance data in the field using mobile data collection devices.
GraniteNet: Sewer pipeline CCTV inspection data is collected and stored using GraniteNet software. The database documents the date, crew, and inspection data for all pipeline inspections.
Wincan Enterprise and Web : Sewer pipeline CCTV inspection data is collected and stored using Wincan software. The database documents the date, crew, and inspection data for all pipeline inspections and stores data via cloud storage.
IRIS: IRIS is an asset management dashboard that utilizes asset data and performs asset management calculations and analyses. The software is designed to supplement asset City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
record systems (e.g., MMS, GIS) by performing asset management calculations that these systems cannot perform. IRIS projects the future asset R&R needs, highlights high-risk assets, estimates the appropriate budget required to mitigate the high-risk assets.
IRIS uses the asset database to estimate a life-cycle cost of ownership for each asset.
IRIS models financial requirements and average investment requirements for any planning horizon, and it will identify the following for each year:
• Estimated replacement cost of each asset
• Estimated total R&R budget required for each year
• Average annual R&R budget for the planning horizon
• Number of assets and estimated replacement cost budget required to address the highest risk assets
• An estimated annual budget required to sustain the future R&R after all highest risk assets have been replaced
The long-range financial needs will be viewable at any level in the asset hierarchy (i.e., by system, by facility, by asset). Where limited budget is a concern, IRIS supports the City with prioritizing investment actions based on risk. This ensures all investments are prioritized and provides a transparent and consistent way to communicate how effectively asset investments are being made.
9.3 Measuring Program Effectiveness and Monitoring
Program Implementation
The City measures and monitors SSMP Program effectiveness and implementation on an annual basis through internal performance reporting, an annual report to the Los Angeles RWQCB, and monthly updates submitted online to SWRCB . These performance measures are used to guide the City’s focus and ultimately improve the City’s effectiveness and efficiency in delivering services. Table 9-1 summarizes the key performance indicators the City uses to track SSMP Program effectiveness and implementation.

9.4 Assessing Success of Preventive Maintenance
Program
The City assesses the success of the preventive maintenance program through after- action review of sewer overflow causes and through review of the performance indicators City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
listed in Table 9-1. Based on sewer overflow performance over the past 5 years and the on-going collection system performance summarized in the Annual Wastewater Reports over the past 5 years, the City has proven to be highly effective at minimizing the number of sewer overflow events.
9.5 Sewer System Management Plan Program Updates
The City is continually reviewing SSO events and SSO performance to identify both site -specific corrective actions to address the cause of a specific sewer overflow event, as well as trends in sewer overflows leading to identification and implementation of targeted or programmatic sewer overflow reduction strategies. Based on this review, th e City determines whether the SSO event is likely to be a one -time event, a potentially recurring event at that specific site, or an indicator of a trend that requires a programmatic solution. As a result of this determination, the City may choose to employ one or more of the actions identified in Table 9-2 to address or mitigate the impacts of a potential failure.
The City evaluates spill trends, frequency, locations, and estimated volumes for all SSO events, implementing corrective actions for each occurrence. Additionally, the City maintains records and reports on all SSOs. These records are reviewed annually to identify necessary improvements, plan capital improvement projects, and adjust maintenance.

10 Sewer System Management Plan Program
Audit and Updates
The WDR requires periodic internal audits to evaluate the effectiveness of the SSMP and SSMP program implementation . This chapter details the City’s plans to conduct such internal audits.
10.1 Regulatory Requirements
The SWRCB Order WQ 2022-0103-DWQ, Section 5.4 – Sewer System Management Plan Audits requires the City to:
The Enrollee shall conduct an internal audit of its Sewer System Management Plan, and implementation of its Plan, at a minimum frequency of once every three years. The audit must be conducted for the period after the end of the Enrollee’s last required audit period.
Within six months after the end of the required 3-year audit period, the Legally Responsible Official shall submit an audit report into the online CIWQS Sanitary Sewer System Database per the requirements in section 3.10 (Sewer System Management Plan Audit Reporting Requirements) of Attachment E1 of this General Order.
Audit reports submitted to the CIWQS Sanitary Sewer System Database will be viewable only to Water Boards staff.
The internal audit shall be appropriately scaled to the size of the system(s) and the number of spills. The Enrollee’s sewer system operators must be involved in completing the audit at minimum, the audit must:
• Evaluate the implementation and effectiveness of the Enrollee’s Sewer System Management Plan in preventing spills;
• Evaluate the Enrollee’s compliance with this General Order; • Identify Sewer System Management Plan deficiencies in addressing ongoing spills and discharges to waters of the State; and
• Identify necessary modifications to the Sewer System Management Plan to correct deficiencies.
The Enrollee shall submit a complete audit report that includes:
• Audit findings and recommended corrective actions;
• A statement that sewer system operator’s input on audit findings has been considered; and
• A proposed schedule for the Enrollee to address the identified deficiencies
10.2 Sewer System Management Plan Program Audit
Process
The City plans to perform an SSMP program audit once every 3 years. The Utilities Superintendent is responsible for initiating the SSMP program audit process. The program audit reviews performance trends and the overall SSMP Program implementation and develops a set of audit findings and proposed corrective actions. The previous audit, input gathered throughout the term, and an assessment of current SSMP performance, are used to construct the initial draft of a new audit. This initial set of audit findings and proposed corrective actions are provided to City staff responsible for various SSMP elements for City of Thousand Oaks Sewer System Management Plan
2025 Sewer System Management Plan Update
their review, comments and additions . The staff responsible for various elements of the SSMP are listed in Attachment B2.
Each SSMP element is evaluated for compliance with SSMP requirements, as well as effectiveness. The Utilities Supervisor coordinates meetings with operators to gather in the field input on SSMP effectiveness. Any deficiencies are identified, along with recommendations for correction. The Utilities Superintendent oversees collection and compilation of input from the program stakeholders and documentation of the findings in the audit report. The final audit report is reviewed by the Primary Authorized Representative (Wastewater Utilities Maintenance Supervisor) before final acceptance.
Audit reports and related materials are maintained in a hard copy, and an electronic file is stored on the City’s server.
Table 10-1 shows the anticipated schedule for SSMP audits and SSMP updates for the next 5 years.
Table 10-1. Sewer System Management Plan Audit and Update Schedule
Year Activity
May 2, 2025 6-year SSMP Update and Certification

May 2, 2030 Internal SSMP Audit (Within six months after the end of the required 3- year audit period)
May 2, 2031 6- year SSMP Update and Certification
10.3 Audit Implementation and Tracking of Results
Once SSMP Program audit findings and corrective actions are finalized, City staff responsible for the various elements of the SSMP Program implementation review the audit findings to determine an appropriate course of action. The Utilities Superintendent tracks implementation progress of audit corrective actions. Any deficiencies in meeting the schedule are identified, and mitigation measures are developed and implemented to ensure corrective actions are addressed.
10.4 Sewer System Management Plan Update Process
The Utilities Superintendent and Utilities Maintenance Supervisor are responsible for ensuring the SSMP is updated when major changes to the SSMP Program implementation occur. If no major changes occur, the SSMP is updated 6 years (at a minimum) from the previous SSMP update, approval, and recertification. The results of the prior SSMP Program audit reports are factored into the SSMP update process. If changes are made, staff are notified and trained accordingly. If no changes are made, staff receive a refresher during regularly scheduled annual training and review sessions. Attachment J includes the Change Log documenting and authorizing the changes associated with this SSMP update.

STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
4 1. INTRODUCTION
This General Order regulates sanitary sewer systems designed to convey sewage. For the purpose of this Order, a sanitary sewer system includes, but is not limited to, pipes, valves, pump stations, manholes, siphons, wet wells, diversion structures and/or other pertinent infrastructure, upstream of a wastewater treatment plant headworks. A sanitary sewer system includes:
• Laterals owned and/or operated by the Enrollee;
• Satellite sewer systems; and/or
• Temporary conveyance and storage facilities, including but not limited to temporary piping, vaults, construction trenches, wet wells, impoundments, tanks and diversion structures.
Sewage is untreated or partially treated domestic, municipal, commercial and/or industrial waste (including sewage sludge), and any mixture of these wastes with inflow or infiltration of stormwater or groundwater, conveyed in a sanitary sewer system.
Sewage contains high levels of suspended solids, non-digested organic waste, pathogenic bacteria, viruses, toxic pollutants, nutrients, oxygen-demanding organic compounds, oils, grease, pharmaceuticals, and other harmful pollutants.
For the purpose of this General Order, a spill is a discharge of sewage from any portion of a sanitary sewer system due to a sanitary sewer system overflow, operational failure, and/or infrastructure failure. Sewage and its associated wastewater spilled from a sanitary sewer system may threaten public health, beneficial uses of waters of the State, and the environment.
This General Order serves as statewide waste discharge requirements and supersedes the previous State Water Resources Control Board (State Water Board) Order 2006-0003-DWQ and amendments thereafter. All sections and attachments of this General Order are enforceable by the State Water Board and Regional Water Quality Control Boards (Regional Water Boards). Through this General Order, the State Water Board requires an Enrollee to:
• Comply with federal and state prohibitions of discharge of sewage to waters of the State, including federal waters of the United States;
• Comply with specifications, and notification, monitoring, reporting and recordkeeping requirements in this General Order that implement the federal Clean Water Act, the California Water Code (Water Code), water quality control plans (including Regional Water Board Basin Plans) and policies;
• Proactively operate and maintain resilient sanitary sewer systems to prevent spills; • Eliminate discharges of sewage to waters of the State through effective implementation of a Sewer System Management Plan;
• Monitor, track, and analyze spills for ongoing system-specific performance improvements; and
• Report noncompliance with this General Order per reporting requirements.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
5 An Enrollee is a public, private, or other non-governmental entity that has obtained approval for regulatory coverage under this General Order, including:
• A state agency, municipality, special district, or other public entity that owns and/or operates one or more sanitary sewer systems:
o greater than one (1) mile in length (each individual sanitary sewer system); o one (1) mile or less in length where the State Water Board or a Regional Water Board requires regulatory coverage under this Order; or • A federal agency, private company, or other non-governmental entity that owns and/or operates a sanitary sewer system of any size where the State Water Board or a Regional Water Board requires regulatory coverage under this Order in response to a history of spills, proximity to surface water, or other factors supporting regulatory coverage.
For the purpose of this Order, a sanitary sewer system includes only systems owned and/or operated by the Enrollee.
2. REGULATORY COVERAGE AND APPLICATION REQUIREMENTS
2.1. Requirements for Continuation of Existing Regulatory Coverage To continue regulatory coverage from previous Order 2006-0003-DWQ under this General Order, within the 60-days-prior-to the Effective Date of this General Order, the Legally Responsible Official of an existing Enrollee shall electronically certify the Continuation of Existing Regulatory Coverage form in the online California Integrated Water Quality System (CIWQS) Sanitary Sewer System Database. The Legally Responsible Official will receive an automated CIWQS-issued Notice of Applicability email, confirming continuation of regulatory coverage under this General Order. All regulatory coverage under previous Order 2006-0003-DWQ will cease on the Effective Date of this Order.
An Enrollee continuing existing regulatory coverage is not required to submit a new application package or pay an application fee for enrollment under this General Order.
The annual fee due date for continued regulatory coverage from previous Order 2006-0003-DWQ to this General Order remains unchanged.
A previous Enrollee of Order 2006-0003-DWQ that fails to certify the Continuation of Existing Regulatory Coverage form in the online CIWQS database by the Effective Date of this Order is considered a New Applicant, and will not have regulatory coverage for its sanitary sewer system(s) until:
• A new application package for system(s) enrollment is submitted per section 2.2 (Requirements for New Regulatory Coverage) below; and

3. FINDINGS
3.1. Legal Authorities
3.1.1. Federal and State Regulatory Authority
The objective of the Clean Water Act is to restore and maintain the chemical, physical, and biological integrity of the waters of the United States (33 U.S.C. 1251). The Water Code authorizes the State Water Board to implement the Clean Water Act in the State and to protect the quality of all waters of the State (Water Code sections 13000 and 13160).
3.1.2. Discharge of Sewage
A discharge of untreated or partially treated sewage is a discharge of waste as defined in Water Code section 13050(d) that could affect the quality of waters of the State and is subject to regulation by waste discharge requirements issued pursuant to Water Code section 13263 and Chapter 9, Division 3, Title 23 of the California Code of Regulations.
A discharge of sewage may pollute and alter the quality of the waters of the State to a degree that unreasonably affects the beneficial uses of the receiving water body or facilities that serve those beneficial uses (Water Code section 13050(l)(1)).
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
8 3.1.3 Water Boards Authority to Require Technical Reports, Monitoring, and Reporting Water Code sections 13267 and 13383 authorize the Regional Water Boards and the State Water Board to establish monitoring, inspection, entry, reporting, and recordkeeping requirements. Water Code section 13267(b), authorizes the Regional Water Boards to “require any person who has discharged, discharges, or is suspected of having discharged or discharging, or who proposes to discharge waste within its region… or is suspected of having discharged or discharging, or who proposes to discharge, waste outside of its region that could affect the quality of water within its region shall furnish, under penalty of perjury, technical or monitoring reports which the regional board requires…In requiring those reports, the regional board shall provide the person with a written explanation with regard to the need for the reports and shall identify the evidence that supports requiring that person to provide the reports.” Water Code section 13267(f) authorizes the State Water Board to require this information if it consults with the Regional Water Boards and determines that it will not duplicate the efforts of the Regional Water Boards. The State Water Board has consulted with the Regional Water Boards and made this determination.
The technical and monitoring reports required by this General Order and Attachment E (Notification, Monitoring, Reporting and Recordkeeping Requirements) are necessary to evaluate and ensure compliance with this General Order. The effort to develop required technical reports will vary depending on the system size and complexity and the needs of the specific technical report. The burden and cost of these reports are reasonable and consistent with the interest of the state in protecting water quality, which is the primary purpose of requiring the reports.
Water Code section 13383(a) authorizes the Water Boards to “establish monitoring, inspection, entry, reporting, and recordkeeping requirements… for any person who discharges, or proposes to discharge, to navigable waters, any person who introduces pollutants into a publicly owned treatment works, any person who owns or operates, or proposes to own or operate, a publicly owned treatment works or other treatment works treating domestic sewage, or any person who uses or disposes, or proposes to use or dispose, of sewage sludge.” Section 13383(b) continues, “the state board or the regional boards may require any person subject to this section to establish and maintain monitoring equipment or methods, including, where appropriate, biological monitoring methods, sample effluent as prescribed, and provide other information as may be reasonably required.”
Reporting of spills from privately owned sewer laterals and systems pursuant to section
5.15 (Voluntary Reporting of Spills from Privately-Owned Sewer Laterals and/or Private Sanitary Sewer Systems) of this General Order is authorized by Water Code section 13225(c) and encouraged by the State Water Board, wherein a local agency may investigate and report on any technical factors involved in water quality control provided the burden including costs of such reports bears a reasonable relationship to the need for the report and the benefits to be obtained therefrom. The burden of reporting private spills under section 5.15 (Voluntary Reporting of Spills from Privately-Owned Sewer Laterals and/or Private Sanitary Sewer Systems) is minimal and is outweighed by the benefit of providing Regional Water Boards an opportunity to respond to these spills
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
9 when an Enrollee, which in many cases has a contractual relationship with the owner of the private system, has knowledge of the spills.
3.1.4. Water Board Authority to Prescribe General Waste Discharge Requirements Water Code section 13263(i) provides that the State Water Board may prescribe general waste discharge requirements for a category of discharges if the State Water Board finds or determines that:
• The discharges are produced by the same or similar operations; • The discharges involve the same or similar types of waste; • The discharges require the same or similar treatment standards; and • The discharges are more appropriately regulated under general waste discharge requirements than individual waste discharge requirements.
Since 2006, the State Water Board has been regulating over 1,100 publicly owned sanitary sewer systems (See section 3.1.5 (Previous Statewide General Waste Discharge Requirements) of this General Order). California also has a large unknown number of unregulated privately owned sanitary sewer systems. All waste conveyed in publicly owned and privately owned sanitary sewer systems (as defined in this General Order) is comprised of untreated or partially treated domestic waste and/or industrial waste. Generally, sanitary sewer systems are designed and operated to convey waste by gravity or under pressure; system-specific design elements and system-specific operations do not change the common nature of the waste, the common threat to public health, or the common impacts on water quality. Spills of waste from a sanitary sewer system prior to reaching the ultimate downstream treatment facility are unauthorized and enforceable by the State Water Board and/or a Regional Water Board. Therefore, spills from sanitary sewer systems are more appropriately regulated under general waste discharge requirements.
As specified in Water Code sections 13263(a) and 13241, the implementation of requirements set forth in this Order is for the reasonable protection of past, present, and probable future beneficial uses of water and the prevention of nuisance. The requirements implement the water quality control plans (Basin Plans) for each Regional Water Board and take into account the environmental characteristics of sewer service areas and hydrographic units within the state. Additionally, the State Water Board has considered water quality conditions that could reasonably be achieved through the coordinated control of all factors that affect water quality, costs associated with compliance with these requirements, the need for developing housing within California, and the need to protect sources of drinking water and other water supplies.
3.1.5. Previous Statewide General Waste Discharge Requirements On May 2, 2006, the State Water Board adopted Order 2006-0003-DWQ serving as Waste Discharge Requirements pursuant to Article 4, Chapter 4, Division 7 of the Water Code (commencing with section 13260) for inadvertent discharges to waters of the State. Order 2006-0003-DWQ prohibited discharges of untreated or partially treated sewage. Order 2006-0003-DWQ also required system-specific management, operation, and maintenance of publicly owned sewer systems greater than one mile in length.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
10 To decrease the impacts on human health and the environment caused by sewage spills, the previous Order required enrollees to develop a rehabilitation and replacement plan that identifies system deficiencies and prioritizes short-term and long-term rehabilitation actions. The previous Order also required enrollees to:
1. Maintain information that can be used to establish and prioritize appropriate Sewer System Management Plan activities; and
2. Implement a proactive approach to reduce spills.
The previous Order required Sewer System Management Plan elements for “the proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management.”
On July 30, 2013, the State Water Board amended General Order 2006-0003-DWQ with Order WQ 2013-0058-EXEC, Amending Monitoring and Reporting Program for Statewide General Waste Discharge Requirements for Sanitary Sewer Systems.
Many enrollees of Order 2006-0003-DWQ have already implemented proactive measures to reduce sewage spills. Other enrollees, however, still need technical assistance and funding to improve sanitary sewer system operation and maintenance for the reduction of sewage spills.
3.1.6. Existing Memorandum of Agreement with California Water Environment Association
The California Water Environment Association is a nonprofit organization dedicated to providing water industry certifications, training, and networking opportunities. The Association’s Technical Certification Program provides accredited sanitary sewer system operator certification for collection system operators and maintenance workers.
On February 10, 2016, the State Water Board entered into a collaborative agreement with the Association titled Memorandum of Agreement Between the California State Water Resources Control Board and the California Water Environment Association - Training Regarding Requirements Set Forth in Statewide General Waste Discharge Requirements for Sanitary Sewer Systems. The Memorandum sets forth collaborative training necessary for regulated sanitary sewer system personnel to operate and maintain a well operating system and ensure full compliance with statewide sewer system regulations.
On March 15, 2018, the State Water Board and the California Water Environment Association amended the existing Memorandum of Agreement to include collaborative outreach and expand training needs associated with further updates to Water Board regulations for sanitary sewer systems. The State Water Board encourages further Agreement updates as necessary to support improved sewer system operations and the professionalism of collection system operators.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
11 3.2. General
3.2.1. Waters of the State
Waters of the State include any surface water or groundwater, including saline waters, within the boundaries of the state as defined in Water Code section 13050(e), and are inclusive of waters of the United States.
3.2.2. Sanitary Sewer System Spill Threats to Public Health and Beneficial Uses Sewage contains high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients, oxygen-demanding organic compounds, oil and grease and other pollutants. Sewage spills may cause a public nuisance, particularly when sewage is discharged to areas with high public exposure such as streets and surface waters used for drinking, irrigation, fishing, recreation, or other public consumption or contact uses.
More specifically, sanitary sewer spills may:
• Adversely affect aquatic life and/or threaten water quality when reaching receiving waters;
• Inadvertently release trash, including plastics;
• Impair the recreational use and aesthetic enjoyment of surface waters by polluting surface water or groundwater;
• Threaten public health through direct public exposure to bacteria, viruses, intestinal parasites, and other microorganisms that can cause serious illness such as gastroenteritis, hepatitis, cryptosporidiosis, and giardiasis; • Negatively impact ecological receptors and biota within surface waters; and • Cause nuisance including odors, closure of beaches and recreational areas, and property damage.
Sanitary sewer system spills may pollute receiving waters and threaten beneficial uses of surface water and groundwater. Potentially threatened beneficial uses include, but are not limited to the following (with associated acronym representations as included in statewide water quality control plans and Regional Water Boards’ Basin Plans):
• Municipal and Domestic Supply (MUN)
• Water Contact Recreation (REC-1) and Non-Contact Water Recreation (REC-2) • Cold Freshwater Habitat (COLD)
• Warm Freshwater Habitat (WARM)
• Native American Culture (CUL)
• Wildlife Habitat (WILD)
• Rare, Threatened, or Endangered Species (RARE)
• Spawning, Reproduction, and/or Early Development (SPWN) • Wetland Habitat (WET)
• Agricultural Supply (AGR)
• Estuarine Habitat (EST)

• Subsistence Fishing (SUB)
• Tribal Tradition and Culture (CUL)
• Tribal Subsistence Fishing (T-SUB)
• Aquaculture (AQUA)
• Marine Habitat (MAR)
• Preservation of Biological Habitats of Special Significance (BIOL) • Migration of Aquatic Organisms (MIGR)
• Shellfish Harvesting (SHELL)
• Industrial Process Supply (PROC)
• Industrial Service Supply (IND)
• Hydropower Generation (POW)
• Navigation (NAV)
• Flood Peak Attenuation/Flood Water Storage (FLD)
• Water Quality Enhancement (WQE)
• Fresh Water Replenishment (FRSH)
• Groundwater Recharge (GWR)
• Inland Saline Water Habitat (SAL)
3.2.3. Proactive Sanitary Sewer System Management to Eliminate Spill Causes Finding 3 of the previous Order, 2006-0003-DWQ, states: “Sanitary sewer systems experience periodic failures resulting in discharges that may affect waters of the state.
There are many factors (including factors related to geology, design, construction methods and materials, age of the system, population growth, and system operation and maintenance), which affect the likelihood of an SSO [sanitary sewer overflow].
A proactive approach that requires Enrollees to ensure a system-wide operation, maintenance, and management plan is in place will reduce the number and frequency of SSOs within the state. This approach will in turn decrease the risk to human health and the environment caused by SSOs.”
Many spills are preventable through proactive attention on sanitary sewer system management using the best practices and technologies available to address major causes of spills, including but not limited to:
• Blockages from sources including but not limited to:
o Fats, oils and grease;
o Tree roots;
o Rags, wipes and other paper, cloth and plastic products; and o Sediment and debris.
• Sewer system damage and exceedance of sewer system hydraulic capacity from identified system-specific environmental, and climate-change impacts, including but not limited to:
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
13 o Sea level rise impacts including flooding, coastal erosion, seawater intrusion, tidal inundation and submerged lands;
o Increased surface water flows due to higher intensity rain events; o Flooding;
o Wildfires and wildfire induced impacts;
o Earthquake induced damage;
o Landslides; and
o Subsidence.
• Infrastructure deficiencies and failures, including but not limited to:
o Pump station mechanical failures;
o System age;
o Construction material failures;
o Manhole cover failures;
o Structural failures; and
o Lack of proper operation and maintenance.
• Insufficient system capacity (temporary or sustained), due to factors including but not limited to:
o Excessive and/or increased storm or groundwater inflow/infiltration; o Insufficient capacity due to population increase and/or new connections from industrial, commercial and other system users; and
o Stormwater capture projects utilizing a sanitary sewer system to convey stormwater to treatment facilities for reuse.
• Community impacts, including but not limited to:
o Power outages;
o Vandalism; and
o Contractor-caused or other third party-caused damages.
3.2.4. Underground Sanitary Sewer System Leakage
Portions of some sanitary sewer systems may leak, causing underground exfiltration (exiting) of sewage from the system. Exfiltrated sewage that remains in the underground infrastructure trench and/or the soil matrix, and that does not discharge into waters of the State (surface water or groundwater) may not threaten beneficial uses.
Underground exfiltrated sewage may threaten beneficial uses if discharged to waters of the State. Exfiltrated sewage that discharges to groundwater may impact beneficial uses of groundwater and pollute groundwater supply. Additionally, if in close proximity, exfiltrated sewage may enter into a compromised underground drainage conveyance system that discharges into a water of the United States, or into groundwater that is hydrologically connected to (feeds into) a water of the United States, thus potentially causing: (1) a Clean Water Act violation, (2) threat and impact to beneficial uses, and/or (3) surface water pollution.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
14 3.2.5. Proactive Sanitary Sewer System Management to Reduce Inflow and Infiltration Excessive inflow (stormwater entering) and infiltration (groundwater seepage entering) to sanitary sewer systems is preventable through proactive sewer system management using the best practices and technologies available. The efficiency of the downstream wastewater treatment processes is dependent on the performance of the sanitary sewer system. When the structural integrity of a sanitary sewer system deteriorates, high volumes of inflow and infiltration can enter the sewer system. High levels of inflow and infiltration increase the hydraulic load on the downstream treatment plant, which can reduce treatment efficiency, lead to bypassing a portion of the treatment process, cause illegal discharge of partially treated effluent, or in extreme situations make biological treatment facilities inoperable (e.g., wash out the biological organisms that treat the waste).
3.3. Water Quality Control Plans, Policies and Resolutions The nine Regional Water Boards have adopted region-specific water quality control plans (commonly referred to as Basin Plans) that designate beneficial uses, establish water quality objectives, and contain implementation programs and policies to achieve those objectives. The State Water Board has adopted statewide water quality control plans, policies and resolutions establishing statewide water quality objectives, implementation programs and initiatives.
3.3.1. State Water Board Antidegradation Policy
On October 28, 1968, the State Water Board adopted Resolution 68-16, titled Statement of Policy with Respect to Maintaining High Quality of Waters in California, which incorporates the federal antidegradation policy. Resolution 68-16 requires that existing water quality be maintained unless degradation is justified based on specific findings.
The continued prohibition of sewage discharges from sanitary sewer systems into waters of the State aligns with Resolution 68-16. A sewage discharge from sanitary sewers to waters of the State is prohibited by this Order. Therefore, this Order does not allow degradation of waters of the State. In addition, this Order: (1) further expands the existing prohibition of sewage discharges to include waters of the State, in addition to waters of the United States as provided in previous Order 2006-0003-DWQ, and (2) enhances the ability for Water Board enforcement of violations of the established prohibitions.
3.3.2. State Water Board Sources of Drinking Water Policy On May 19,1988, the State Water Board adopted Resolution 88-63 (amended on February 1, 2006), titled Sources of Drinking Water, establishing state policy that all waters of the State, with certain exceptions, are suitable or potentially suitable for municipal or domestic supply.
3.3.3. State Water Board Cost of Compliance Resolution
On September 24, 2013, the State Water Board adopted Resolution 2013-0029, titled Directing Actions in Response to Efforts by Stakeholders on Reducing Costs of
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER

15 Compliance While Maintaining Water Quality Protection. Through this resolution, the State Water Board committed to continued stakeholder engagement in identifying and implementing measures to reduce costs of compliance with regulatory orders while maintaining water quality protection and improving regulatory program outcomes.
3.3.4. State Water Board Human Right to Water Resolution On February 16, 2016, the State Water Board adopted Resolution 2016-0010, titled Adopting the Human Right to Water as a Core Value and Directing its Implementation in Water Board Programs and Activities, addressing the human right to water as a core value and directing Water Board programs to implement requirements to support safe drinking water for all Californians.
On November 16, 2021, the State Water Board adopted Resolution 2021-0050 titled Condemning Racism, Xenophobia, Bigotry, and Racial Injustice, and Strengthening Commitment to Racial Equity, Diversity, Inclusion, Access, and Anti-racism. Among other actions, through Resolution 2021-0050, the State Water Board, in summary as corresponding to this General Order, reaffirms its commitment to its Human Right to Water resolution, upholding that every human being in California deserves safe, clean, affordable, and accessible water for human consumption, cooking, and sanitation purposes. Resolution 2021-0050 provides the State Water Board commitment to:
• Protect public health and beneficial uses of waterbodies in all communities, including communities disproportionately burdened by wastes discharge of waste to land and surface water;
• Restore impaired surface waterbodies and degraded aquifers; and • Promote multi-benefit water quality projects.
Through Resolution 2021-0050, the State Water Board also commits to expanding implementation of its Climate Change Resolution to address the disproportionate effects of extreme hydrologic conditions and sea-level rise on Black, Indigenous, and people of color communities, prioritizing:
• The right to safe, clean, affordable, and accessible drinking water and sanitation; • Sustainable management and protection of local groundwater resources; • Healthy watersheds; and
• Access to surface waterbodies that support subsistence fishing.
On June 7, 2022, the State Water Board adopted a Resolution, titled Authorizing the Executive Director or Designee to Enter into One or More Multi-Year Contracts Up to a Combined Sum of $4,000,000 for a Statewide Wastewater Needs Assessment, supporting the equitable access to sanitation for all Californians and implementation of Resolutions 2016-0010 and 2021-0050.
This General Order supports the State Water Board priority in collecting a comprehensive set of data for California’s wastewater systems, including sanitary sewer systems. Data reported per the requirements of this Order will be used with data from other Water Boards’ programs, to further develop criteria and create a statewide risk
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
16 framework to prioritize critical funding and infrastructure investments for California’s most vulnerable populations, including disadvantaged or severely disadvantaged communities with inadequate or failing sanitation systems and threatened access to healthy drinking water supplies.
3.3.5. State Water Board Open Data Resolution
On July 10, 2018, the State Water Board adopted Resolution 2018-0032, titled Adopting Principles of Open Data as a Core Value and Directing Programs and Activities to Implement Strategic Actions to Improve Data Accessibility and Associated Innovation, directing regulatory programs to assure all monitoring and reporting requirements support the State Water Boards’ Open Data Initiative.
3.3.6. State Water Board Response to Climate Change
On March 7, 2017, the State Water Board adopted Resolution 2017-0012, titled Comprehensive Response to Climate Change, requiring a proactive response to climate change in all California Water Board actions, with the intent to embed climate change consideration into all programs and activities.
3.4. California Environmental Quality Act
The adoption of this Order is an action to reissue general waste discharge requirements that is exempt from the California Environmental Quality Act (Public Resources Code section 21000 et seq.) because it is an action taken by a regulatory agency to assure the protection of the environment and the regulatory process involves procedures for protection of the environment (Cal. Code Regs., Title 14, section 15308). In addition, the action to adopt this Order is exempt from CEQA pursuant to Cal. Code Regs., Title 14, section 15301, to the extent that it applies to existing sanitary sewer collection systems that constitute “existing facilities” as that term is used in sections 15301 and 15302, to the extent that it results in the repair or replacement of existing systems involving negligible or no expansion of capacity.
3.5. State Water Board Funding Assistance for Compliance with Water Board Water Quality Orders
The State Water Board, Division of Financial Assistance administers the implementation of the State Water Board financial assistance programs, per Board-adopted funding policies. Among other funding areas, the Division administers loan and grant funding for the planning and construction of wastewater and water recycling facilities per funding program-specific policies and guidelines. Applicants may apply for Clean Water State Revolving Fund low-interest loan, Small Community Wastewater grant funding assistance, and other funding available at the time of application, for some of the costs associated with complying with this General Order.

The following maintenance and inspection procedures are to be followed for relieving built-up pressure in hydro equipment in addition to the above maintenance inspections performed when applicable:
a. Built-up air pressure must be relieved after the Fleet Service Division performs work on hoses, pumps, valves, or tanks, and before resuming normal operations.
Additionally, these maintenance and inspection procedures should be followed whenever the tanks have been fully emptied, the pumps have run dry, or a new hydro hose is installed on the hydro truck reel.
b. Follow the standard operating procedures a through f as outlined in section 6.0, Hydro Cleaning and Vacuuming Procedures.
c. After lowering the nozzle safely into the manhole channel, turn on the water to the hydro nozzle and allow the pump to idle while the air is expelled from the system.
You will notice fluctuations between water and air, which may take a few minutes to fully purge. Once the hydro pressure and flow have stabilized, proceed to step h in section 6.0, Hydro Cleaning and Vacuuming, and hydro clean the sewer line as usual to ensure all air is cleared from the system.
d. A competent person who has received hands -on training on safe operations will be responsible for operating equipment to relieve built-up air in hydro equipment.
Note: The hydro cleaning nozzle should never be operated outside confinement of a sewer line through the utility access hole.

Spill Emergency Response Plan Procedures
PROCEDURES:
Regardless of size, the primary focus of overflows, spills and collection (main line) breaks should be on public and employee safety. During any wastewater emergency, follow the steps included below.
Appendix B includes additional contact information and a list of emergency equipment. Appendix C includes a flow chart for quick-reference by staff.
The Municipal Service Center (805) 449-2499 may be informed of a spill and authorized staff (such as the Utilities Maintenance Supervisor during normal hours or standby phone after normal hours) are notified. Normal working hours are Monday through Thursday from 6:30 AM to 5 PM. Other forms of communication that can indicate a potential SSO include SCADA alarms from lift stations or alarms from one of the ten stationary flow meters throughout the sanitary sewer collection system. SCADA alarms directly alert field staff during working hours or personnel on standby phone after hours, while flow meter alarms alert US3, in which US3 then verifies then notifies the City.
Upon notification, responding staff shall arrive at the scene, perform preliminary assessment, take appropriate action, and communicate results to the designated supervisor. Upon notification of a potential sewer overflow, a City responder is dispatched onsite with the goal to arrive within 30 minutes.
The Utilities Maintenance Supervisor (Supervisor) or Crew Leader shall respond immediately to any emergencies. Crew Leaders or field staff may investigate other service requests or less- urgent complaints...
The Supervisor or Crew Leader shall evaluate the situation and make the following determinations:
i. City service area or Triunfo Water and Sanitation District - All wastewater emergencies occurring outside the City's wastewater service area are included in Triunfo Water and Sanitation District and will be the responsibility of that District; the City of Thousand Oaks will only respond as a mutual-assistance agency when requested and resources are deemed available. The Triunfo Water and Sanitation District will be responsible for making the appropriate notifications to the necessary agencies and directing City personnel activities if applicable through mutual aid.
ii. Triunfo Water and Sanitation District:
Emergency/24-hour contact: (805) 389-9406
iii. Public vs. private Issue – The City of Thousand Oaks ownership and responsibility does not include private sewer laterals but does include City -owned public facility laterals.
Private property situations will be handled by the Building Division of the Community Development Department (CDD). Publicly-owned laterals for p ublic facilities such as; parks, libraries, Los Robles Greens golf course, etc. must be handled through Public Works in coordination with other appropriate departments. City crews will typically check the City main to determine responsibility by opening upstream and downstream sewer main manholes. City staff will attempt to contain or recover wastewater resulting from private spills to prevent wastewater from reaching waterways and storm drains. iv. Emergency vs. Non -Emergency - If multiple emergencies or service requests are received in the same timeframe, Supervisor or Crew Leader shall prioritize the situations
Spill Emergency Response Plan Procedures
for assignment of crews. For any man-made or intentionally caused (e,g, terrorist event) emergencies and disaster, please reference the City’s Emergency Response Plan. v. Determine Next Steps to Best Address the Situation
The Supervisor or Crew Leader shall notify designated City personnel, (City Staff Notifications). Notifications to staff are made on a case-by-case basis and may include:

The City is operating under two different sets of requirements for collection system spill water quality monitoring, spill notification and spill reporting with one set provided in the Statewide General Waste Discharge Requirements for Sanitary Sewer Systems WQ 2022-0103-DWQ (WDR) and the other set provided in Order R4 -2019-0137 (Hill Canyon Treatment Plant
Spill Emergency Response Plan Procedures
NPDES permit)1. The following list summarizes the City’s approach regarding the two sets of requirements.
o The City will provide notifications and reporting of collection system SSOs per the WDR and this reporting will be through CIWQS. Hill Canyon Treatment Plant unauthorized discharge notification and reporting procedures will be per Order R4-2019-0137. o The City will perform water quality monitoring for all Category 1 SSOs per the Water Quality Monitoring Program Plan (Appendix D), which incorporates changes from the WQ 2022-0103-DWQ (WDR) into the previous plan which was based on the Hill Canyon Treatment Plant Order R4-2019-0137. The City will identify in CIWQS when sampling is completed, which parameters were sampled and attach the monitoring results.
Environmental Compliance staff and HCTP Laboratory Supervisor shall be notified of any discharge. HCTP Laboratory Supervisor is responsible for NPDES compliance related to Order R4-2019-0137 (Hill Canyon Treatment Plant NPDES permit) including annual report for NPDES regarding SSOs.
For discharges reaching an active waterway (Category 1 spills) the HCTP Lab Supervisor will oversee water quality monitoring per the Water Quality Monitoring Program Plan (Appendix D).
The HCTP Laboratory Supervisor will arrange posting notices as directed by Ventura County Environmental Health Division (VCEHD). Typically, signs shall be posted at the spill site and as necessary to reasonably warn the public if a spill occurs and there is a possibility of wastewater entering recreational water or other waterways where the public may come in contact.
Additional contacts that may be notified on a case -by-case basis or utilized for improved response are included in Appendix B.
Prepare an appropriate plan and address the spill. This should take into consideration following appropriate safety protocols and all reasonable steps to minimize or prevent any discharge that has a reasonable likelihood of adversely affecting human health or the environment.
Addressing the spill should generally adhere to the following procedures:
i. Secure the area and restrict access to only authorized and relevant personnel. Traffic control and area security may include signage, caution tape, traffic cones and truck mounted arrow board.
ii. Typically, relieve any stoppage immediately with Hydro truck or bypass the stoppage (or pipeline break) by pumping from an upstream manhole to a downstream manhole. iii. Containment should begin in a safe and orderly manner before any repair work. Use sandbags, dirt, absorbent towels, or other materials where appropriate. Main concern is to clear the stoppage.
iv. Dam the spill or watercourse so all contaminated water is contained. All attempts must be made to prevent any amount from reaching an active watercourse or storm drain, or from
1 The City summarized these two different sets of requirements in an email to the Regional Water Quality Control Board staff Andrew Choi and Veronica Cuevas on 8/17/2021 and scheduled a meeting to discuss these requirements. The City received an email cancelling the meeting and identified that Regional Water Quality Control Board staff would work on a response. No response was received by the City at the time of developing this document.
Spill Emergency Response Plan Procedures
impairing public access or health. This includes containing private lateral spills from entering an active water course or storm drain until private lateral owner clears blockage. v. Pump any spillage including solid and liquid materials to a downstream manhole, or vacuum spillage for transport. Normally, if the spill is in the gutter, procedure is to vacuum residual out of the gutter, wash down area and then vacuum what is washed down .
Remove contaminated dirt if spill is not on a street. Chemicals are not typically applied for disinfection.
vi. Refer to storm drain atlas (hard copy or GIS based version) to follow storm drain routes for vacuuming any amount that reached a storm drain. In cases where accessible or appropriate, the City will flush and collect spill from the storm drain conveyance system. vii. For non-City storm drain access issues in Ventura County Protection District owned and operated storm drain conveyance systems, contact:
Wendell Ho Senior Public Works Inspector at (805) 312-7106 or Wendell.Ho@ventura ,org or call Ventura County Watershed Protection District at (805) 654-2069. viii. If necessary and when large volumes are released, use portable pumps and bypassing or hydro combination trucks to recover the spill.
The Supervisor will request or dispatch any equipment, tools, or safety equipment necessary to address the situation, contain the spill, break any stoppage, and/or commence repair/cleanup activities.
After the spill has been addressed, the Supervisor or Crew Leader will initiate any additional repair or cleanup activities needed. City equipment will be mobilized, and contractors and suppliers should be contacted as necessary and appropriate. i. After sewer main spill recovery, the line may be televised to evaluate condition of line and cause of stoppage. Sewer main may become a hot spot for cleaning or recommended for replacement/rehabilitation.
Lift Station Failures
i. Olsen Road Lift Station includes a containment tank that can contain flow for approximately 72 hours under typical flow rates in the event of lift station failure. The lift station may also be by-passed using a 6-inch pump owned by the City.
ii. Lawrence Drive Lift Station includes a by-pass that can transfer flow to the Unit E gravity main in the event of lift station failure.
Record Keeping
i. Maintain individual SSO records for a minimum of 5 years from the date of the SSO including but not limited to:
a. Complaint records documenting how the enrollee responded to all notifications of possible or actual SSOs, both during and after business hours, including complaints that do not result in SSOs. Each complaint record shall, at a minimum, include the following information:
1. Date, time, and method of notification.
2. Date and time the complainant or informant first noticed the SSO.
Spill Emergency Response Plan Procedures
3. Narrative description of the complaint, including any information the caller can provide regarding whether or not the complainant or informant reporting the potential SSO knows if the SSO has reached surface waters, drainage channels or storm drains.
4. Follow-up return contact information for the complainant or informant for each complaint received, if not reported anonymously.
5. Final resolution of the complaint.
b. Records documenting steps and/or remedial actions undertaken by enrollee, using all available information, to comply with section D.7 of the SSS WDRs.

CATEGORIES DEFINITIONS (See Section 5.13.1. Spill Categories of Order WQ 2022- 0103-DWQ, for Spill Categories)
CATEGORY 1 A Category 1 spill is a spill of any volume of sewage from or caused by a sanitary sewer system regulated under this General Order that results in a discharge to:
• A surface water, including a surface water body that contains no flow or volume of water; or
• A drainage conveyance system that discharges to surface waters when the sewage is not fully captured and returned to the sanitary sewer system or disposed of properly.
Any spill volume not recovered from a drainage conveyance system is considered a discharge to surface water, unless the drainage conveyance system discharges to a dedicated stormwater infiltration basin or facility.
A spill from an Enrollee-owned and/or operated lateral that discharges to a surface water is a Category 1 spill; the Enrollee shall report all Category 1 spills per section 3.1 of Attachment E1 (Notification, Monitoring, Reporting and Recordkeeping Requirements) of this General Order.

STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
4 1. INTRODUCTION
This General Order regulates sanitary sewer systems designed to convey sewage. For the purpose of this Order, a sanitary sewer system includes, but is not limited to, pipes, valves, pump stations, manholes, siphons, wet wells, diversion structures and/or other pertinent infrastructure, upstream of a wastewater treatment plant headworks. A sanitary sewer system includes:
• Laterals owned and/or operated by the Enrollee;
• Satellite sewer systems; and/or
• Temporary conveyance and storage facilities, including but not limited to temporary piping, vaults, construction trenches, wet wells, impoundments, tanks and diversion structures.
Sewage is untreated or partially treated domestic, municipal, commercial and/or industrial waste (including sewage sludge), and any mixture of these wastes with inflow or infiltration of stormwater or groundwater, conveyed in a sanitary sewer system.
Sewage contains high levels of suspended solids, non-digested organic waste, pathogenic bacteria, viruses, toxic pollutants, nutrients, oxygen-demanding organic compounds, oils, grease, pharmaceuticals, and other harmful pollutants.
For the purpose of this General Order, a spill is a discharge of sewage from any portion of a sanitary sewer system due to a sanitary sewer system overflow, operational failure, and/or infrastructure failure. Sewage and its associated wastewater spilled from a sanitary sewer system may threaten public health, beneficial uses of waters of the State, and the environment.
This General Order serves as statewide waste discharge requirements and supersedes the previous State Water Resources Control Board (State Water Board) Order 2006-0003-DWQ and amendments thereafter. All sections and attachments of this General Order are enforceable by the State Water Board and Regional Water Quality Control Boards (Regional Water Boards). Through this General Order, the State Water Board requires an Enrollee to:
• Comply with federal and state prohibitions of discharge of sewage to waters of the State, including federal waters of the United States;
• Comply with specifications, and notification, monitoring, reporting and recordkeeping requirements in this General Order that implement the federal Clean Water Act, the California Water Code (Water Code), water quality control plans (including Regional Water Board Basin Plans) and policies;
• Proactively operate and maintain resilient sanitary sewer systems to prevent spills; • Eliminate discharges of sewage to waters of the State through effective implementation of a Sewer System Management Plan;
• Monitor, track, and analyze spills for ongoing system-specific performance improvements; and
• Report noncompliance with this General Order per reporting requirements.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
5 An Enrollee is a public, private, or other non-governmental entity that has obtained approval for regulatory coverage under this General Order, including:
• A state agency, municipality, special district, or other public entity that owns and/or operates one or more sanitary sewer systems:
o greater than one (1) mile in length (each individual sanitary sewer system); o one (1) mile or less in length where the State Water Board or a Regional Water Board requires regulatory coverage under this Order; or • A federal agency, private company, or other non-governmental entity that owns and/or operates a sanitary sewer system of any size where the State Water Board or a Regional Water Board requires regulatory coverage under this Order in response to a history of spills, proximity to surface water, or other factors supporting regulatory coverage.
For the purpose of this Order, a sanitary sewer system includes only systems owned and/or operated by the Enrollee.
2. REGULATORY COVERAGE AND APPLICATION REQUIREMENTS
2.1. Requirements for Continuation of Existing Regulatory Coverage To continue regulatory coverage from previous Order 2006-0003-DWQ under this General Order, within the 60-days-prior-to the Effective Date of this General Order, the Legally Responsible Official of an existing Enrollee shall electronically certify the Continuation of Existing Regulatory Coverage form in the online California Integrated Water Quality System (CIWQS) Sanitary Sewer System Database. The Legally Responsible Official will receive an automated CIWQS-issued Notice of Applicability email, confirming continuation of regulatory coverage under this General Order. All regulatory coverage under previous Order 2006-0003- DWQ will cease on the Effective Date of this Order.

2.3. Regulatory Coverage Transfer
Regulatory coverage under this General Order is not transferable to any person or party except after an existing Enrollee submits a written request for a regulatory coverage transfer to the Deputy Director, at least 60 days in advance of any proposed system ownership transfer. The written request must include a written agreement between the existing Enrollee and the new Enrollee containing:
• Acknowledgement that the transfer of ownership is solely of an existing system with an existing waste discharge identification (WDID) number; • The specific ownership transfer date in which the responsibility and regulatory coverage transfer between the existing Enrollee and the new Enrollee becomes effective; and
• Acknowledgement that the existing Enrollee is liable for violations occurring up to the ownership transfer date and that the new Enrollee is liable for violations occurring on and after the ownership transfer date.
The Deputy Director will consider approval of the written request. If approved, the Deputy Director will issue a Notice of Applicability letter which serves as an approved transfer of regulatory coverage to the new Enrollee.
3. FINDINGS
3.1. Legal Authorities
3.1.1. Federal and State Regulatory Authority
The objective of the Clean Water Act is to restore and maintain the chemical, physical, and biological integrity of the waters of the United States (33 U.S.C. 1251). The Water Code authorizes the State Water Board to implement the Clean Water Act in the State and to protect the quality of all waters of the State (Water Code sections 13000 and 13160).
3.1.2. Discharge of Sewage
A discharge of untreated or partially treated sewage is a discharge of waste as defined in Water Code section 13050(d) that could affect the quality of waters of the State and is subject to regulation by waste discharge requirements issued pursuant to Water Code section 13263 and Chapter 9, Division 3, Title 23 of the California Code of Regulations. A discharge of sewage may pollute and alter the quality of the waters of the State to a degree that unreasonably affects the beneficial uses of the receiving water body or facilities that serve those beneficial uses (Water Code section 13050(l)(1)).
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
8 3.1.3 Water Boards Authority to Require Technical Reports, Monitoring, and Reporting Water Code sections 13267 and 13383 authorize the Regional Water Boards and the State Water Board to establish monitoring, inspection, entry, reporting, and recordkeeping requirements. Water Code section 13267(b), authorizes the Regional Water Boards to “require any person who has discharged, discharges, or is suspected of having discharged or discharging, or who proposes to discharge waste within its region… or is suspected of having discharged or discharging, or who proposes to discharge, waste outside of its region that could affect the quality of water within its region shall furnish, under penalty of perjury, technical or monitoring reports which the regional board requires…In requiring those reports, the regional board shall provide the person with a written explanation with regard to the need for the reports and shall identify the evidence that supports requiring that person to provide the reports.” Water Code section 13267(f) authorizes the State Water Board to require this information if it consults with the Regional Water Boards and determines that it will not duplicate the efforts of the Regional Water Boards. The State Water Board has consulted with the Regional Water Boards and made this determination.
The technical and monitoring reports required by this General Order and Attachment E (Notification, Monitoring, Reporting and Recordkeeping Requirements) are necessary to evaluate and ensure compliance with this General Order. The effort to develop required technical reports will vary depending on the system size and complexity and the needs of the specific technical report. The burden and cost of these reports are reasonable and consistent with the interest of the state in protecting water quality, which is the primary purpose of requiring the reports.
Water Code section 13383(a) authorizes the Water Boards to “establish monitoring, inspection, entry, reporting, and recordkeeping requirements… for any person who discharges, or proposes to discharge, to navigable waters, any person who introduces pollutants into a publicly owned treatment works, any person who owns or operates, or proposes to own or operate, a publicly owned treatment works or other treatment works treating domestic sewage, or any person who uses or disposes, or proposes to use or dispose, of sewage sludge.” Section 13383(b) continues, “the state board or the regional boards may require any person subject to this section to establish and maintain monitoring equipment or methods, including, where appropriate, biological monitoring methods, sample effluent as prescribed, and provide other information as may be reasonably required.”
Reporting of spills from privately owned sewer laterals and systems pursuant to section
5.15 (Voluntary Reporting of Spills from Privately-Owned Sewer Laterals and/or Private Sanitary Sewer Systems) of this General Order is authorized by Water Code section 13225I and encouraged by the State Water Board, wherein a local agency may investigate and report on any technical factors involved in water quality control provided the burden including costs of such reports bears a reasonable relationship to the need for the report and the benefits to be obtained therefrom. The burden of reporting private spills under section 5.15 (Voluntary Reporting of Spills from Privately-Owned Sewer Laterals and/or Private Sanitary Sewer Systems) is minimal and is outweighed by the benefit of providing Regional Water Boards an opportunity to respond to these spills
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
9 when an Enrollee, which in many cases has a contractual relationship with the owner of the private system, has knowledge of the spills.
3.1.4. Water Board Authority to Prescribe General Waste Discharge Requirements Water Code section 13263(i) provides that the State Water Board may prescribe general waste discharge requirements for a category of discharges if the State Water Board finds or determines that:
• The discharges are produced by the same or similar operations; • The discharges involve the same or similar types of waste; • The discharges require the same or similar treatment standards; and • The discharges are more appropriately regulated under general waste discharge requirements than individual waste discharge requirements.
Since 2006, the State Water Board has been regulating over 1,100 publicly owned sanitary sewer systems (See section 3.1.5 (Previous Statewide General Waste Discharge Requirements) of this General Order). California also has a large unknown number of unregulated privately owned sanitary sewer systems. All waste conveyed in publicly owned and privately owned sanitary sewer systems (as defined in this General Order) is comprised of untreated or partially treated domestic waste and/or industrial waste. Generally, sanitary sewer systems are designed and operated to convey waste by gravity or under pressure; system- specific design elements and system-specific operations do not change the common nature of the waste, the common threat to public health, or the common impacts on water quality. Spills of waste from a sanitary sewer system prior to reaching the ultimate downstream treatment facility are unauthorized and enforceable by the State Water Board and/or a Regional Water Board. Therefore, spills from sanitary sewer systems are more appropriately regulated under general waste discharge requirements.
As specified in Water Code sections 13263(a) and 13241, the implementation of requirements set forth in this Order is for the reasonable protection of past, present, and probable future beneficial uses of water and the prevention of nuisance. The requirements implement the water quality control plans (Basin Plans) for each Regional Water Board and take into account the environmental characteristics of sewer service areas and hydrographic units within the state.
Additionally, the State Water Board has considered water quality conditions that could reasonably be achieved through the coordinated control of all factors that affect water quality, costs associated with compliance with these requirements, the need for developing housing within California, and the need to protect sources of drinking water and other water supplies.
3.1.5. Previous Statewide General Waste Discharge Requirements On May 2, 2006, the State Water Board adopted Order 2006-0003-DWQ serving as Waste Discharge Requirements pursuant to Article 4, Chapter 4, Division 7 of the Water Code (commencing with section 13260) for inadvertent discharges to waters of the State. Order 2006- 0003-DWQ prohibited discharges of untreated or partially treated sewage. Order 2006-0003- DWQ also required system-specific management, operation, and maintenance of publicly owned sewer systems greater than one mile in length.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
10 To decrease the impacts on human health and the environment caused by sewage spills, the previous Order required enrollees to develop a rehabilitation and replacement plan that identifies system deficiencies and prioritizes short-term and long-term rehabilitation actions. The previous Order also required enrollees to:
1. Maintain information that can be used to establish and prioritize appropriate Sewer System Management Plan activities; and
2. Implement a proactive approach to reduce spills.
The previous Order required Sewer System Management Plan elements for “the proper and efficient management, operation, and maintenance of sanitary sewer systems, while taking into consideration risk management.”
On July 30, 2013, the State Water Board amended General Order 2006 -0003-DWQ with Order WQ 2013 -0058-EXEC, Amending Monitoring and Reporting Program for Statewide General Waste Discharge Requirements for Sanitary Sewer Systems.
Many enrollees of Order 2006-0003-DWQ have already implemented proactive measures to reduce sewage spills. Other enrollees, however, still need technical assistance and funding to improve sanitary sewer system operation and maintenance for the reduction of sewage spills.
3.1.6. Existing Memorandum of Agreement with California Water Environment Association
The California Water Environment Association is a nonprofit organization dedicated to providing water industry certifications, training, and networking opportunities. The Association’s Technical Certification Program provides accredited sanitary sewer system operator certification for collection system operators and maintenance workers.
On February 10, 2016, the State Water Board entered into a collaborative agreement with the Association titled Memorandum of Agreement Between the California State Water Resources Control Board and the California Water Environment Associati–n - Training Regarding Requirements Set Forth in Statewide General Waste Discharge Requirements for Sanitary Sewer Systems. The Memorandum sets forth collaborative training necessary for regulated sanitary sewer system personnel to operate and maintain a well operating system and ensure full compliance with statewide sewer system regulations.
On March 15, 2018, the State Water Board and the California Water Environment Association amended the existing Memorandum of Agreement to include collaborative outreach and expand training needs associated with further updates to Water Board regulations for sanitary sewer systems. The State Water Board encourages further Agreement updates as necessary to support improved sewer system operations and the professionalism of collection system operators.

ORDER 2022-0103-DWQ December 6, 2022
11 3.2. General
3.2.1. Waters of the State
Waters of the State include any surface water or groundwater, including saline waters, within the boundaries of the state as defined in Water Code section 13050(e), and are inclusive of waters of the United States.
3.2.2. Sanitary Sewer System Spill Threats to Public Health and Beneficial Uses Sewage contains high levels of suspended solids, pathogenic organisms, toxic pollutants, nutrients, oxygen-demanding organic compounds, oil and grease and other pollutants. Sewage spills may cause a public nuisance, particularly when sewage is discharged to areas with high public exposure such as streets and surface waters used for drinking, irrigation, fishing, recreation, or other public consumption or contact uses.
More specifically, sanitary sewer spills may:
• Adversely affect aquatic life and/or threaten water quality when reaching receiving waters;
• Inadvertently release trash, including plastics;
• Impair the recreational use and aesthetic enjoyment of surface waters by polluting surface water or groundwater;
• Threaten public health through direct public exposure to bacteria, viruses, intestinal parasites, and other microorganisms that can cause serious illness such as gastroenteritis, hepatitis, cryptosporidiosis, and giardiasis; • Negatively impact ecological receptors and biota within surface waters; and • Cause nuisance including odors, closure of beaches and recreational areas, and property damage.
Sanitary sewer system spills may pollute receiving waters and threaten beneficial uses of surface water and groundwater. Potentially threatened beneficial uses include, but are not limited to the following (with associated acronym representations as included in statewide water quality control plans and Regional Water Boards’ Basin Plans):
• Municipal and Domestic Supply (MUN)
• Water Contact Recreation (REC-1) and Non-Contact Water Recreation (REC-2) • Cold Freshwater Habitat (COLD)
• Warm Freshwater Habitat (WARM)
• Native American Culture (CUL)
• Wildlife Habitat (WILD)
• Rare, Threatened, or Endangered Species (RARE)
• Spawning, Reproduction, and/or Early Development (SPWN) • Wetland Habitat (WET)
• Agricultural Supply (AGR)
• Estuarine Habitat (EST)

• Groundwater Recharge (GWR)
• Inland Saline Water Habitat (SAL)
3.2.3. Proactive Sanitary Sewer System Management to Eliminate Spill Causes Finding 3 of the previous Order, 2006-0003-DWQ, states: “Sanitary sewer systems experience periodic failures resulting in discharges that may affect waters of the state. There are many factors (including factors related to geology, design, construction methods and materials, age of the system, population growth, and system operation and maintenance), which affect the likelihood of an SSO [sanitary sewer overflow].
A proactive approach that requires Enrollees to ensure a system-wide operation, maintenance, and management plan is in place will reduce the number and frequency of SSOs within the state. This approach will in turn decrease the risk to human health and the environment caused by SSOs.”
Many spills are preventable through proactive attention on sanitary sewer system management using the best practices and technologies available to address major causes of spills, including but not limited to:
• Blockages from sources including but not limited to:
o Fats, oils and grease;
o Tree roots;
o Rags, wipes and other paper, cloth and plastic products; and o Sediment and debris.
• Sewer system damage and exceedance of sewer system hydraulic capacity from identified system-specific environmental, and climate-change impacts, including but not limited to:
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
13 o Sea level rise impacts including flooding, coastal erosion, seawater intrusion, tidal inundation and submerged lands;
o Increased surface water flows due to higher intensity rain events; o Flooding;
o Wildfires and wildfire induced impacts;
o Earthquake induced damage;
o Landslides; and
o Subsidence.
• Infrastructure deficiencies and failures, including but not limited to:
o Pump station mechanical failures;
o System age;
o Construction material failures;
o Manhole cover failures;
o Structural failures; and
o Lack of proper operation and maintenance.
• Insufficient system capacity (temporary or sustained), due to factors including but not limited to:
o Excessive and/or increased storm or groundwater inflow/infiltration; o Insufficient capacity due to population increase and/or new connections from industrial, commercial and other system users; and
o Stormwater capture projects utilizing a sanitary sewer system to convey stormwater to treatment facilities for reuse.
• Community impacts, including but not limited to:
o Power outages;
o Vandalism; and
o Contractor-caused or other third party-caused damages.
3.2.4. Underground Sanitary Sewer System Leakage
Portions of some sanitary sewer systems may leak, causing underground exfiltration (exiting) of sewage from the system. Exfiltrated sewage that remains in the underground infrastructure trench and/or the soil matrix, and that does not discharge into waters of the State (surface water or groundwater) may not threaten beneficial uses.
Underground exfiltrated sewage may threaten beneficial uses if discharged to waters of the State. Exfiltrated sewage that discharges to groundwater may impact beneficial uses of groundwater and pollute groundwater supply. Additionally, if in close proximity, exfiltrated sewage may enter into a compromised underground drainage conveyance system that discharges into a water of the United States, or into groundwater that is hydrologically connected to (feeds into) a water of the United States, thus potentially causing: (1) a Clean Water Act violation, (2) threat and impact to beneficial uses, and/or (3) surface water pollution.
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
14 3.2.5. Proactive Sanitary Sewer System Management to Reduce Inflow and Infiltration Excessive inflow (stormwater entering) and infiltration (groundwater seepage entering) to sanitary sewer systems is preventable through proactive sewer system management using the best practices and technologies available. The efficiency of the downstream wastewater treatment processes is dependent on the performance of the sanitary sewer system. When the structural integrity of a sanitary sewer system deteriorates, high volumes of inflow and infiltration can enter the sewer system. High levels of inflow and infiltration increase the hydraulic load on the downstream treatment plant, which can reduce treatment efficiency, lead to bypassing a portion of the treatment process, cause illegal discharge of partially treated effluent, or in extreme situations make biological treatment facilities inoperable (e.g., wash out the biological organisms that treat the waste).
3.3. Water Quality Control Plans, Policies and Resolutions The nine Regional Water Boards have adopted region-specific water quality control plans (commonly referred to as Basin Plans) that designate beneficial uses, establish water quality objectives, and contain implementation programs and policies to achieve those objectives.
The State Water Board has adopted statewide water quality control plans, policies and resolutions establishing statewide water quality objectives, implementation programs and initiatives.
3.3.1. State Water Board Antidegradation Policy
On October 28, 1968, the State Water Board adopted Resolution 68-16, titled Statement of Policy with Respect to Maintaining High Quality of Waters in California, which incorporates the federal antidegradation policy. Resolution 68-16 requires that existing water quality be maintained unless degradation is justified based on specific findings.
The continued prohibition of sewage discharges from sanitary sewer systems into waters of the State aligns with Resolution 68-16. A sewage discharge from sanitary sewers to waters of the State is prohibited by this Order. Therefore, this Order does not allow degradation of waters of the State. In addition, this Order: (1) further expands the existing prohibition of sewage discharges to include waters of the State, in addition to waters of the United States as provided in previous Order 2006-0003-DWQ, and
(2) enhances the ability for Water Board enforcement of violations of the established prohibitions.
3.3.2. State Water Board Sources of Drinking Water Policy On May 19,1988, the State Water Board adopted Resolution 88-63 (amended on February 1, 2006), titled Sources of Drinking Water, establishing state policy that all waters of the State, with certain exceptions, are suitable or potentially suitable for municipal or domestic supply.
3.3.3. State Water Board Cost of Compliance Resolution
On September 24, 2013, the State Water Board adopted Resolution 2013-0029, titled Directing Actions in Response to Efforts by Stakeholders on Reducing Costs of
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
15 Compliance While Maintaining Water Quality Protection. Through this resolution, the State Water Board committed to continued stakeholder engagement in identifying and implementing measures to reduce costs of compliance with regulatory orders while maintaining water quality protection and improving regulatory program outcomes.
3.3.4. State Water Board Human Right to Water Resolution On February 16, 2016, the State Water Board adopted Resolution 2016-0010, titled Adopting the Human Right to Water as a Core Value and Directing its Implementation in Water Board Programs and Activities, addressing the human right to water as a core value and directing Water Board programs to implement requirements to support safe drinking water for all Californians.
On November 16, 2021, the State Water Board adopted Resolution 2021-0050 titled Condemning Racism, Xenophobia, Bigotry, and Racial Injustice, and Strengthening Commitment to Racial Equity, Diversity, Inclusion, Access, and Anti-racism. Among other actions, through Resolution 2021-0050, the State Water Board, in summary as corresponding to this General Order, reaffirms its commitment to its Human Right to Water resolution, upholding that every human being in California deserves safe, clean, affordable, and accessible water for human consumption, cooking, and sanitation purposes. Resolution 2021- 0050 provides the State Water Board commitment to:
• Protect public health and beneficial uses of waterbodies in all communities, including communities disproportionately burdened by wastes discharge of waste to land and surface water;
• Restore impaired surface waterbodies and degraded aquifers; and • Promote multi-benefit water quality projects.
Through Resolution 2021-0050, the State Water Board also commits to expanding implementation of its Climate Change Resolution to address the disproportionate effects of extreme hydrologic conditions and sea-level rise on Black, Indigenous, and people of color communities, prioritizing:
• The right to safe, clean, affordable, and accessible drinking water and sanitation; • Sustainable management and protection of local groundwater resources; • Healthy watersheds; and
• Access to surface waterbodies that support subsistence fishing.
On June 7, 2022, the State Water Board adopted a Resolution, titled Authorizing the Executive Director or Designee to Enter into One or More Multi-Year Contracts Up to a Combined Sum of $4,000,000 for a Statewide Wastewater Needs Assessment, supporting the equitable access to sanitation for all Californians and implementation of Resolutions 2016-0010 and 2021-0050.
This General Order supports the State Water Board priority in collecting a comprehensive set of data for California’s wastewater systems, including sanitary sewer systems. Data reported per the requirements of this Order will be used with data from other Water Boards’ programs, to further develop criteria and create a statewide risk
STATEWIDE SANITARY SEWER SYSTEMS GENERAL ORDER
ORDER 2022-0103-DWQ December 6, 2022
16 framework to prioritize critical funding and infrastructure investments for California’s most vulnerable populations, including disadvantaged or severely disadvantaged communities with inadequate or failing sanitation systems and threatened access to healthy drinking water supplies.
3.3.5. State Water Board Open Data Resolution
On July 10, 2018, the State Water Board adopted Resolution 2018-0032, titled Adopting Principles of Open Data as a Core Value and Directing Programs and Activities to Implement Strategic Actions to Improve Data Accessibility and Associated Innovation, directing regulatory programs to assure all monitoring and reporting requirements support the State Water Boards’ Open Data Initiative.
3.3.6. State Water Board Response to Climate Change
On March 7, 2017, the State Water Board adopted Resolution 2017-0012, titled Comprehensive Response to Climate Change, requiring a proactive response to climate change in all California Water Board actions, with the intent to embed climate change consideration into all programs and activities.
3.4. California Environmental Quality Act
The adoption of this Order is an action to reissue general waste discharge requirements that is exempt from the California Environmental Quality Act (Public Resources Code section 21000 et seq.) because it is an action taken by a regulatory agency to assure the protection of the environment and the regulatory process involves procedures for protection of the environment (Cal. Code Regs., Title 14, section 15308). In addition, the action to adopt this Order is exempt from CEQA pursuant to Cal. Code Regs., Title 14, section 15301, to the extent that it applies to existing sanitary sewer collection systems that constitute “existing facilities” as that term is used in sections 15301 and 15302, to the extent that it results in the repair or replacement of existing systems involving negligible or no expansion of capacity.
3.5. State Water Board Funding Assistance for Compliance with Water Board Water Quality Orders
The State Water Board, Division of Financial Assistance administers the implementation of the State Water Board financial assistance programs, per Board-adopted funding policies. Among other funding areas, the Division administers loan and grant funding for the planning and construction of wastewater and water recycling facilities per funding program-specific policies and guidelines. Applicants may apply for Clean Water State Revolving Fund low-interest loan, Small Community Wastewater grant funding assistance, and other funding available at the time of application, for some of the costs associated with complying with this General Order.
Funding applicants may obtain further information regarding current funding opportunities, and Division of Financial Assistance staff contact information at the following website:

17 Section 13477.6 of the Water Code authorizes the Small Community Grant Fund. The Small Community Grant Fund allows the State Water Board to provide grant funding assistance to small, disadvantaged communities and small severely disadvantaged communities that may not otherwise be able to afford a loan or similar financing for projects to comply with requirements of this General Order. The State Water Board also considers loan forgiveness on a disadvantaged community-specific basis.
For disadvantaged communities’ wastewater needs, the State Water Board places priority on the funding of projects that address:
• Public health;
• Violations of waste discharge requirements and National Pollutant Discharge Elimination System (NPDES) permits;
• Providing sewer system service to existing septic tank owners; and • High priority public health and water quality concerns identified by a Regional Water Board.
3.6. Notification to Interested Parties
On January 31, 2022, the State Water Board notified interested parties and persons of its intent to reissue Sanitary Sewer Systems General Order 2006-0003-DWQ by issuing a draft General Order for a 60-day public comment period. State Water Board staff conducted extensive stakeholder outreach and encouraged public participation in the adoption process for this General Order. On March 15, 2022, the State Water Board held a public meeting to hear and consider oral public comments. The State Water Board considered all public comments prior to adopting this General Order.
THEREFORE, IT IS HEREBY ORDERED, that pursuant to Water Code sections 13263, 13267, and 13383 this General Order supersedes Order 2006-0003-DWQ, Order WQ 2013-0058-EXEC, and any amendments made to these Orders thereafter, except for enforcement purposes and to meet the provisions contained in Division 7 of the Water Code (commencing with section 13000) and regulations adopted thereunder, and the provisions of the Clean Water Act and regulations and guidelines adopted thereunder, the Enrollee shall comply with the requirements in this Order.
