12 Although private property owners own the entire length of the service lateral associated with their property, the Utility will clear blockages from the property line clean out to the City sewer main (“service the lower lateral”) as a courtesy service to the public; provided a property line cleanout exists, and the Utility is made aware of any problems or backups. Overall lateral maintenance and repair is sole responsibility of property owner.

The Utility has offers inexpensive clean out installations for all customer classes, including residential, commercial, industrial, and institutional. The Utility utilizes installed property line clean outs in order to provide maintenance to lower laterals as a courtesy when requested by customers.

The sanitary sewer system also includes two large pump stations, each with a flow meter, and five smaller unmetered lift stations. All stations have radio telemetry to monitor operating status.

Pump and Lift Station information is included in the following table:

The Utility owns and operates the sanitary sewer system, with exceptions as described below:
• Sewer Laterals – Pursuant to City Ordinance 1901 passed 11/27/2012, property owners are responsible for maintenance and operation of the entire lateral up to the wye connection to the public main.
• Private Onsite Sewer Systems – Private onsite sewer systems are the responsibility of the property owner for the associated property, up to the connection to the public main or manhole.
• Sewer Maintained by Other Agencies – City of San Jose and City of Sunnyvale own and maintain a portion of sewer lines within City of Santa Clara right-of-way, as shown in provided sewer maps.

The Utility’s sewer system includes several instances of unique constraints and boundary conditions.
• Siphons – The Utility’s sewer system includes 59 siphons as listed in Table 4-6. • Transportation Agency Right-of-Way – Caltrans owns the right-of-way along El Camino Real and the highways/freeways traversing the City. County owns the right-of-way along the expressways traversing the City. Encroachment permitting and/or maintenance agreements are required to perform work in their respective right-of-way. • Rail Agency Right-of-Way – Rail belonging to United Pacific Railroad (UPRR), Caltrain, and other transit agencies traverse the City, resulting in utility constraints across rail agency right-of-way. Encroachment permitting and/or maintenance agreements are required to perform work in their respective right-of-way.
• Surface Water Right-of-Way – Santa Clara Valley Water District (SCVWD) owns the right- of-way along Guadalupe River, Calabazas Creek, San Tomas Aquino Creek, and Saratoga Creeks traversing the City, resulting in utility constraints crossing and adjacent to surface waters. Encroachment permitting and/or maintenance agreements are required to perform work in SCVWD right-of-way.
• Department of Toxic Substances Control (DTSC) Regulated Sites – Several locations in City right-of-way are considered DTSC Regulated Sites due to contaminated soils. DTSC must be notified prior to work in these locations.
• Cupertino Sanitary District Tributary Lines – The Utility has an agreement with CUSD to convey flows through the Utility’s sanitary sewer system to the Regional Wastewater Facility (RWF).

4.1 Updated Map of Sewer System
Collection
System Maps

The City of Santa Clara Water and Sewer Utilities DepartmentUtility prepares and updates the sanitary sewer system maps (block books) continuously in CAD and/or GIS map and every three to four years publishes in a bounded 11” x 17” combed binding.publishes compiled updates approximately every 4 years.

These updates are based on as-built information collected by the City’s Public Works Field Services Division inspection staff and Sewer Ddivision operations and maintenance personnel.

REQUIREMENTS
The Plan Introduction section must provide a general description of the local sewer system management program and discuss Plan implementation and updates. The Plan must include the items listed below that are appropriate and applicable to the Enrollee’s system.

An up-to-date map(s) of the sanitary sewer system, and procedures for maintaining and providing State and Regional Water Board staff access to the map(s). The map(s) must show gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable stormwater conveyance facilities within the sewer system service area boundaries.

Requirement:
(a) Maintain an up-to-date map of the sanitary sewer system, showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable storm water conveyance facilities;
(b) Describe routine preventivePreventative operation and maintenance activities by staff and contractors, including a system for scheduling regular maintenance and cleaning of the sanitary sewer system with more frequent cleaning and maintenance targeted at known problem areas. The Preventative Maintenance (PM) program should have a system to document scheduled and conducted activities, such as work orders;
(c) Develop a rehabilitation and replacement plan to identify and prioritize system deficiencies and implement short-term and long-term rehabilitation actions to address each deficiency. The program should include regular visual and TV inspections of manholes and sewer pipes, and a system for ranking the condition of sewer pipes and scheduling rehabilitation. Rehabilitation and replacement should focus on sewer pipes that are at risk of collapse or prone to more frequent blockages due to pipe defects. Finally, the rehabilitation and replacement plan should include a capital improvement plan that addresses proper management and protection of the infrastructure assets. The plan shall include a time schedule for implementing the short- and long-term plans plus a schedule for developing the funds needed for the capital improvement plan;

Routine Operations and Maintenance
The City of Santa Clara has a populationpopulation of approximately 129,000. The sewer system serves residential customers as well as commercial and industrial businesses. The City’s service area is contained within City limits. The City also accepts flow from Cupertino Ssanitary District (CUSDCuSD) under an agreement executed in 1985.

All wastewater collected by the City’s sewer system is conveyed to the jointly owned San JoseSan José – Santa Clara Regional Wastewater Facility (Facility) for treatment. The Facility is a tertiary treatment facility that discharges to Artesian Slough, tributary to Coyote Creek and South San Francisco Bay, and supplies recycled water to over 270 customers via the South Bay Water Recycling Program.

The sanitary sewer system consists of approximately 270 miles of sewer mains. The decade of construction, size, and material of mains are shown in the table on the following page.

Sewer System Management Plan
City of Santa Clara Water & Sewer Utility
19 Although private property owners own the entire length of the service lateral associated with their property, the City will clear blockages from the property line clean out to the City sewer main (“service the lower lateral”) as a courtesy service to the public; provided a property line cleanout exists and the City is made aware of any problems or backups. Overall lateral maintenance and repair is sole responsibility of property owner.

The City of Santa Clara has been offering inexpensive clean out installations and to date has installed over 9,600 since records have been kept. The sanitary sewer system also includes two large pump stations, each with a flow meter, and five smaller unmetered lift stations. All stations have radio telemetry to monitor operating status.

Pump and Lift Station information is included in the following table:

All sewer pumps utilize industry-leading equipment that is not only efficient but features the latest advancements in no-clog impeller designs that are superior to technology used previously. The Utility standardizes pump product lines enabling each station to have a backup pump readily available at the sewer shop. The system also includes over 5,300 manholes, 2 force mains (totaling over 3 miles), 58 siphons, and an additional main line meter station to measure flow at the Guadalupe outfall to the conveyance pipe to the local Treatment Facility; called the Guadalupe metering station.

Previous documentation of the division’s maintenance strategies includes a 2009 Sanitary Sewer Management Plan, adopted by City Council in April 2009, and a 2014 Sanitary Sewer Management Plan, adopted by City Council in February 2014 o.April 720. Both documents provide basic instructions and schedules for inspecting, cleaning, and servicing the City’s sewer system facilities and maintaining records of the work completed. The current organization documented Commented [LT8]: Qualifier not needed and we don’t
have small pump station category so there’s no
differentiation.

Commented [LT9]: Already mentioned in previous

20 here is an update and supersedes the previous SSMPs. The City strives to balance its strong emphasis on customer service with a comprehensive and efficient preventative maintenance program.

4.2 Preventative Operation and Maintenance Activities

Goals of the PreventivePreventative Maintenance Program The main objectives of the preventative maintenance program are to:
• Assure the longest possible lifespanMaximize service life of the City’s sanitary sewer system • Avoid major failures of the system
• Minimize sanitary sewer overflows and backups and
• Respond appropriately to customer concerns and requests.

Major components of the program , in pursuit of these goals, have beenare identified as follows:
• Prioritized cleaning and maintenance of sewer system components • Customer service
• Ongoing condition assessment
• Capital Improvement s Program
• Staff training and providing adequate resources like combination cleaning trucks, CCTV cameras, etc.
• Maintenance of maps of the sanitary sewer system maps, and equipment and supplies inventories
• Use of SCADA systems to monitor and control sewer facilities remotely. • Use of a computerized maintenance management system (CMMS) in combination with CCTV files available on a server for viewing at any time any time.to manage assets and track work orders for scheduled preventivepreventative maintenance and customer requests.

• Previous documentation of the Utility’s maintenance strategies includes a 2009 Sewer System Management Plan, adopted by City Council in April 2009, a 2014 Sewer System Management Plan, adopted by City Council in February 2014, and a 2019 Sewer System Management Plan, adopted by City Council on April 7, 2020. The listed documents provide basic instructions and

REQUIREMENTS
A scheduling system and a data collection system for preventative operation and maintenance activities conducted by staff and contractors.

The scheduling system must include:
(a) Inspection and maintenance activities
(b) Higher-frequency inspections
(c) Maintenance of known problem areas including areas with tree root problems
(d) Regular visual and closed-circuit television (CCTV) inspections of manholes and sewer pipes.

Commented [LT11]: Belongs in 4.2
Commented [BM12]: Will need to use either
preventative or preventive. They both mean the same
thing and both are acceptable. I suggest preventative
as it is used most often in utilities. Will need to do a search for both as they are scattered throughout.

The Utility’sUtility’s goal is to clean and inspect the entire length of their sewer system within 8 years. This includes replacing deficient mains identified by a PACPthe NASSCO PACP pipe rating system. Regular jetting is scheduled for 36 weeks of the year, which allows time for storm season preparations. HFC’s and siphons, however, are cleaned monthly throughout the year. The current inspection and cleaning cycle began April 2023, and is anticipated to be completed by April 2031.Currently, the City is on schedule to complete full condition assessment of the entire collection system by the end of March 21, 2021. As of December 2019, the City has completed the assessment of over 1.2 million linear feet. The City has also made repairs to over 400 sections of pipe that had a rating of PACP 5.

Cleaning is done systematically by location throughout the City, thereby assuring that all mains are included in each cleaning cycle. Crews begin the cycle at the southern part of the City (higher elevation) and works towards the northern part of the City (lower elevation), progressing through the map books. Condition assessment is performed in conjunction with Repair needs identified during cleaning. CCTV videos and reports are uploaded and stored in the CityUtility’s CMMS. If a defect is observed that may require immediate attention, it is reported to the Assistant Sanitary Sewer Superintendent to assess next steps and whether an emergency repair is warranted. are recorded in the field in the map books, and a work order request is completed in order to facilitate the scheduling of the repairs.

The Crew Supervisor sets priorities for completing repairs, based on the condition of the main and the potential impacts.

Crews are responsible for documenting the work that they complete each day. Th e Utility e Utility utilizes a work orderComputerized Maintenance Management System (CMMS) software system called Lucity which maintains all work completed by maintenance crew staff. The Utility also utilizes an inspection management software called ITpipes to integrate inspection dat a into the CMMS.Lucity is utilized by the Department for its Computerized Maintenance Management System (CMMS).

Areas Needing More Frequent Cleaning (HFC’s or Higher Frequency Cleanings) Areas Needing More Frequent Cleaning (HFC’s or Higher Frequency Cleanings) The DivisionUtility has identified “HFC’s” throughout the City, which are locations in the sewer system that need more frequent cleaning to prevent buildup of grease inside the lines, obstructions, backflow, and SSOspills (Table 4-37). The knowntypicalknown causes for hotspots HFCs include:

● Gravity lines with minimal slope ● Residential FOG
● Commercial FOG ● Root problems
● Surcharging ● Smaller siphons

Some HFC’s remain the same over time, especially flat lines and smaller siphons.

Others are added to and subtractedor removed from the list as problems are resolved and new problems are identified.

HFC’s are identified during routine cleaning and entered into Lucity. Problem areas are noted in the work order system at the time they are identified, and then transferred to the list of HFC’s for further attention. New/recently problematic HFC areas are televised and either cleaned or repaired and assessed as to causality; with any findings noted and left on, or removed fromused to revise the the HFC list based on best management practices.

Crews have a goal of cleaning all HFC’s monthly or as close to 30 days apart as possible. Lucity keeps track of the list as they are cleaned, thereby recording their progress and assuring that all HFC’s are cleaned regularly.

In addition to the smaller siphons that are included on the list of HFC’s, larger siphonsSiphons are inspected regularly and jetted as necessary. A list of siphons is located in Table 4-48.

28 However, thetThe UtilityUtility also currently holds a contract with a private company to perform major pump maintenance. or repairs due to the expertise and resources needed. Contracting major pump maintenance activities allows the Utility to focus more of its resources on the preventative maintenance program throughout the sewer system.

Root Control
Root Control
AFollowing cleaning, or as a part of a customer service request, the UtilityUtility may treat s laterals and smaller mains for root control by means of physical removal or using a foam product.

The Utility may offer treatment for root controls to private sewer laterals as a courtesy when requested by a resident or when necessary, as pre-treatment to provide inspection services.

There is no official program to provide this service, and this service is offered on an as- requested basis only. Crew A is responsible for foaming laterals.

The current protocol includes cutting the roots and removing them from the sewer, waiting four (4) to six (6) weeks, foaming, and then going back to double check the affected segment of pipe.

Manhole Inspection and Repairs
Manhole Inspection and Repairs
Crew B is responsible for inspecting and cleaning manholes. Manholes are inspected as mains are jetted. In this way, all manholes are inspected approximately once every threethree (3)eight (8) years during the completion of system-wide CCTV. Any needed repairs are identified and documented in the block book by the Crew Supervisor. Repair needs are transferred to and completed by Crew A orSewer Division staff or may be contracted to a private company.

Manhole inspections and cleaning are documented along with other task completion on the daily report form.

Rehabilitation and Replacement Plan
Rehabilitation and Replacement Plan
In addition to visual inspections of manholes and identification of abnormal conditions in sewers mains during routine cleaning, it has been the practice of the Sewer Division to perform closed- circuit television (CCTV) inspections (also known as television, TV, or video inspections), as necessary to investigate problem areas in sewer mains or laterals. The Division has also developed a routine CCTV inspection and condition assessment program for laterals and main lines. The City owns a CCTV truckthat went into service in 2015 and is operated by City staff.

CCTV inspections are also completed as necessary to ensure that new construction meets the City’s design standards. All related findings, videos, and information about condition assessment is kept in our CMMS on-site.Observations from system-wide CCTV are reviewed by Sewer Division staff and coordinated with the Utility’s Engineering Division to prioritize rehabilitation and replacement. Severity of observed defects, location of pipe, proximity to other repair candidates, age, size, and material of pipe are considered and used to advise capital project planning.

Capital Improvement Program / Major Repairs
The Public Works’ Engineering Department is responsible for managing the Public Works’ portion of the City’s Capital Improvements Program, which includes Sewer Division capital improvement projects.

If major deficiencies warranting rehabilitation or replacement of sewer system components are identified as a result of routine main-line cleaning or CCTV inspections that require resources beyond those available to the Division, the Assistant Sanitary Sew er Superintendent contacts the Principal Engineer – Water and Sewer.

Receiving and Responding to a Service Request

The City of Santa Clara’s website instructs customers to call the Sewer Division staff directly during business hours at 408-615-2000 to report sewer-related problems. Work orders are created to track reported sewer-related issues and a During business hours, one Maintenance Worker is dispatched to perform the initial evaluations of investigate the problem and resolve it if possible. Additional crew members are called in if necessary.

Customers are instructed to call 408-615-5640 on weekends, holidays and after business hours. These after-hours calls are received by the Water/Electric Ccontrol Operators. Sewer Division staff and qualified Water Division staff may choose to be on- call to respond to after- hours service calls. The Water/Electric Control Operators maintain a list of these on -call crew members.ssupport the Utility's staff as needed for serviceStaff has working relationships with multiple local vendors.

The following procedure has been established for responding to a customer service request for a backup:

• First Responder: The Utility sends out one person to check the public main and the lower lateral (if there is an existing property line cleanout) to determine if there is a stoppage in the Utility-owned system, or if the stoppage is in the customer- owned lateral. The first responder then meets with the customer to discuss the location of the problem.
• If the stoppage is determined to be in the lower lateral of the customer’s lateral, Sewer Division staff will run a drain auger into the public main in an attempt to clear the blockage. Staff may also elect to plunge the blockage if it is deemed risky to insert the drain auger. For other types of problems, or items relating to blockages in the upper portion of the lateral, the first responder will advise the customer of appropriate actions to take.
• If the stoppage is determined to be in the main line, the first responder will call in a jet truck and crew to relieve the problem. After clearing the stoppage, the line will be assessed and scheduled for further work if necessary. A CCTV inspection will b e completed if the stoppage was particularly problematic, or if the inspection is deemed useful for other reasons.
• If the crew cannot clear the stoppage, the line will be repaired. If a problem is found that requires repairs, the Assistant Sanitary Sewer Superintendent will be notified and will call USA. The Crew Supervisor will mark the work area and will get his crew to saw out, excavate, complete the repair, backfill and clean up. • In addition, the crew will also perform repairs to manholes that were either damaged during the process of clearing the stoppage or if any prior deficiencies were discovered.

After business hours, upon becoming aware of a spill (either through the initial service call or by notification from other sources), the Water/Electric Operators call Sewer and W ater Division Maintenance Workers and supervisory staff, working their way up the chain-of-command, until a City employee is reached. Utility workers try to respond to service calls within 30 minutes. The private contractor will be instructed to contact the Operators immediately upon becoming aware of a spill.

Program to Ensure an Appropriate Response in all Overflows

Responding to a Service Request
During business hours, the first Responder calls the Crew Supervisor or Assistant Sanitary Sewer Superintendent if additional staff or equipment is needed to assist with response. Each Sewer Division truck is equipped with a radio. After business hours, th e first Responder calls the Water/Electric control Operators if additional staff or equipment are needed to assist with response. The Operators then call in other staff.

The Sewer Division maintains a spill-response truck/trailer with appropriate equipment and materials. First Responders may call for the truck/trailer to the service request location.

Additional equipment is called in as needed for larger spills. • A binder containing all Sewer Division SOPs, and a packet of additional spill reference and documentation material are included in the truck/trailer. Also, included in the Emergency Response Procedures in Appendix H, is the: S pill Response SOP:

Conduct post-spill assessments of spill response activities

Management and supervisory staff that could include the Compliance Manager, Water and Sewer Operations Manager, Water and Sewer Superintendent, Assistant Water and Sanitary Sewer Superintendent including the Assistant Director and Director of Water and Sew er Utilities will conduct post-spill assessments to discuss response activities, equipment, and infrastructure deficiencies

Documentation and reporting all spill events categories

Water and Sewer Utilities staff will document and report spills for Categories 1, 2,3,4 as outlined in Attachment E1 of the Statewide Sanitary Sewer Systems General Order 2022 - 0103-DWQ. Utility staff will document spill responses on the Spill Emergency Response Report forms that are utilized in the field. Pertinent information is documented in the Computer Maintenance Management System (CMMS) utilizing Lucity database software. The Utility will update spill related information in the CIWQS database accordin g to the requirements of the Order.

Annually, review and assess effectiveness of the Spill Emergency Response Plan

On an annual basis the Utility’s management and supervisory staff will meet annually and review the Spill Response Plan with a focus on spill response and containment, documentation procedures, training requirements, communication, CIWQS reporting and coordination between agencies including the Public Works stormwater Division. Any outcomes from the annual evaluation will be documented and implemented with modification being made to the Spill Emergency Response Plan.

Lateral Responsibility

Property owners own the entire length of their laterals. Property owners are responsible for dealing with blockages and backups resulting from blockages in their lateral. Utility employees do not work on the customer’s upper lateral under any circumstances. If there is a blockage in a lateral and there is not an existing property line cleanout, the property owner is responsible for dealing with the blockage and backup. The Utility is not responsible for damages due to blockages in these laterals. Utility employees will check the lower lateral and will attempt to clear blockages as a courtesy service, provided that there is a property line cleanout.

Sewer Division staff will explain this policy to the customer and offer to schedule a property line cleanout installation so that future backups caused by problems in the lower lateral couldan be more easily identified and resolved.

41 lateral is defined included entity that owns the lateral:
“Sewer lateral” (same as “sewer service lateral”) means the sewer connection piping used to convey sewage from a building or facility on a parcel (private or public property) to the City - owned sewer main. Each sewer lateral is owned by the entity that owns the property or facility from which that sewer lateral serves to convey sewage.”

Under 13.10.040 - Maintenance and inspection of sewer connections defines the requirements:
“Each user shall keep his/her sewer connections and sewer lateral(s) in good order at his/her own expense and shall be liable for all damages resulting from failure to do so. Each owner shall maintain their sewer lateral free from displaced joints, open jo ints, root intrusions, substantial deterioration of pipe material, cracks, leaks, inflow or infiltration of extraneous water, grease and sediment deposits or other similar conditions, defects, or obstructions likely to cause or increase the chance of blockage. A City inspector shall be admitted at all reasonable hours to any premises connected with the sewer system, for the purpose of checking plumbing fixtures, protecting the rights of the City, and determining facts relevant to the establishment, computation, and billing of the sewer service charges provided for in this chapter, including, in the case of industrial users, examination of the users’ books for the purpose of checking the quantities of industrial waste produced. “

The Utility will on a case-by-case basis determine whether to report sewer discharges to California Office of Emergency Services (OES) from Privately-Owned Sewer Laterals and or Private Sanitary Sewer Systems that discharges to waters of the State, or a storm drain conveyance system that discharges to the waters of the State. The City may notify California Office of Emergency Services (OES) for spills from private laterals on a case by case basis.

42 These procedures are described by the following operating procedures, flowcharts and tables, which are included as part of this Emergency Response Plan located in Appendix H:

• Receiving a Service Request During Business Hours;
• Receiving a Service Request After Business Hours, Weekends and Holidays; • Responding to a Service Request;
• Sanitary Sewer Overflow Response;
• Spill Notification;
• Complete the paperwork;
• Sewage Spill Responsibility;
• Additional Support for Emergency Operations;
• SSO Water Quality Sampling SOP

Identification of the Overflow Emergency Response Plan responders:

Receiving a Service Request
The City of Santa Clara’s website instructs customers to call the sewer division directly during business hours at 408-615-2000 to report sewer-related problems. During business hours, one Maintenance Worker is dispatched to perform the initial evaluations of the problem and resolve it if possible. Additional crew members are called in if necessary.

Customers are instructed to call 408-615-5640 on weekends, holidays and after business hours.

These after-hours calls are received by the Water/Electric control Operators. Sewer Division and qualified Water Division Maintenance Workers may choose to be on call to respond to after- hours service calls. The Water/Electric Control Operators maintain a list of these on -call crew members. The City is also will contract with local private contractors to handle spill related during regular hours and after-hours calls. Staff has working relationships with multiple local vendors

The following procedure has been established for responding to a customer service request for a backup:

First Responder: The Utility sends out one person to check the City main and the lower lateral to determine if there is a stoppage in the City-owned system, or if the stoppage is in the customer- owned lateral. The first responder then meets with the customer to discuss the location of the problem.

If the stoppage is determined to be in the lower lateral, The City will run a drain auger out to the city main in attempt to clear the blockage. They may also elect to plunge the blockage if it is deemed risky to insert the drain auger. For other types of problems, or items relating to blockages in the upper portion of the lateral, the first responder will advise the customer of appropriate actions to take.

If the stoppage is determined to be in the main line, the first responder will call in a jet truck and crew to relieve the problem. After clearing the stoppage, the line will be assessed and scheduled for further work if necessary. A CCTV inspection will be completed if the stoppage was particularly problematic, or if the inspection is deemed useful for other reasons.

If the crew cannot clear the stoppage, the line will be repaired. If a problem is found that requires repairs, the Assistant Sanitary Sewer Superintendent will be notified and will call USA. The Crew Supervisor will mark the work area and will get his crew to saw out, excavate, complete the repair, backfill and clean up.

In addition, the crew will also perform repairs to manholes that were either damaged during the process of clearing the stoppage or if any prior deficiencies were discovered.

A Sewer/Water Division employee is immediately notified when a spill occurs. After business Sewer System Management Plan
City of Santa Clara Water & Sewer Utility
43 hours, upon becoming aware of a spill (either through the initial service call or by notification from other sources), the Water/Electric Operators call Sewer and Water Division Maintenance Workers and supervisory staff, working their way up the chain-of-command, until a city employee is reached. City workers try to respond to service calls within 30 minutes. The private contractor will be instructed to contact the Operators immediately upon becoming aware of a spill.

Program to Ensure an appropriate Response in all Overflows Responding to a Service Request
During business hours, the first Responder calls the Crew Supervisor or Assistant Sanitary Sewer Superintendent if additional staff or equipment is needed to assist with response. Each Sewer Division truck is equipped with a radio. After business hours, the first Responder calls the Water/Electric control Operators if additional staff or equipment are needed to assist with response. The Operators then call in other staff.

The Sewer Division maintains an SSO-response truck/trailer. First Responders may call for the truck/trailer to the service request location. Additional equipment is called in as needed for larger spills.

A binder containing all Sewer division SOPs and a packet of additional SSO reference and documentation material are included in the truck/trailer. Also included in the Emergency Response Procedures in Appendix H, is the SOP: Sanitary Sewer Overflow (SSO) Response a nd SOP: Sanitary Sewer Overflow Sampling.

Lateral Responsibility
Property owners own the entire length of their laterals. Property owners are responsible for dealing with blockages and backups resulting from blockages in their lateral. City employees do not work on the customer’s upper lateral under any circumstances. I f there is a blockage in a lateral and there is not an existing property line cleanout, the property owner is responsible for dealing with the blockage and backup. The City is not responsible for damages due to blockages in these laterals. City employees will check the lower lateral provided that there is a property line cleanout.

Procedures to ensure prompt notification to appropriate regulatory agencies The Water and Sewer Operations Manager or any registered Data Submitters (DS) is responsible for entering reports of SSOs into the California Integrated water quality system (CIWQS), as required by the Monitoring and Reporting Program in the State Water Board Order No. 2006 - 0003-DWQ. The Water and Sewer Operations Manager is responsible for certifying SSO reports to CIWQS. Two-hour notifications, as required, may be made by the Primary LRO, and in the event of their absence, notification may be made by the Assistant Water & Sewer Superintendent, Assistant Sanitary Sewer Superintendent, Assistant Director, or Director. The Water and Sewer Operations Manager is also responsible for completing the SSMP Audit Report every two years.

The SSO Notification and Reporting Flowcharts are referenced in Element 2 as Figures 2 -1 and 2-2.

Disposal of Fats, Oils, and Grease
Although no FOG disposal sites are located in the City of Santa Clara, there are ample opportunities for proper disposal in the immediate vicinity of the City. All FOG collected within the city limits are usually handled by commercial grease disposal compa nies. The CityUtility provides a list of local grease hauling companies to restaurants and food preparation facilities. A copy of this hand-out is attached in Appendix I.

Legal Authority to Prohibit Discharges
The legal authority of the City rests in the City of Santa Clara’s Charter (ref: Section 400, Article IV Powers) and adopted City code. Specific to waste discharge requirements for sanitary sewer system, Code Title 13, Chapter 13.10 “Sewers” codifies all requirements related to sewers. The specific Authority to prohibit discharges can be found in Appendix B.

• Storm and other waters - 13.10.230
• Grease, oils, fats - 13.10.270
• Solid or viscous matter - 13.10.280

Requirements to Install Grease Removal Devices
The following standards can be found in as provided in Appendix B.

• Maintenance Requirements – 13.10.380
• Best Management Practices Requirements – 13.10.380
• Record Keeping - 13.10.520
• Reporting Requirements – 13.10.520

Authority to Inspect
The City of Santa ClaraUtility has sufficient staff to inspect FOG producing facilities or operations, including a Compliance Manager, Code Enforcement Officer and Code Enforcement Technician. The City Code includes sections to address inspection and enforcement issues which can be found in Appendix B.

• Power to Inspect – 13.10.570
• Responsibility – 13.10.530
• Publication of Users in Significant Non-Compliance - 13.10.660

Identification of FOG “Hot Spots”
The CityUtility of Santa Clara’s Sewer utility Crews havehas identified “Hot Spots” in the collection system that may be caused by a variety of reasons including FOG. In order to mitigate any potential blockage or SSOspill resulting from these anomalies, these areas are on a more frequent inspection and cleaning regimen. The list of City FOG Hotspots is referenced in Element

4. Sewer System Management Plan
City of Santa Clara Water & Sewer Utility
47 Source Control Measures to Prevent SSOSpills/blockages of FOG The discharger is required to use Best Management Practices (BMP) or have in place a Grease Interceptor or for smaller kitchens at a minimum a Grease Trap on appropriate outlets.

The FOG Control Program is designed for inspections as well as education for the discharger.

The inspection includes a tour of the facility, use of BMPs, physical inspection of any/all grease removal devices and review of all records related to the cleaning, pumping and repair of these devices. Discrepancies found during the inspection are duly noted and followed -up after corrective action is scheduled.

The City of Santa Clara adopted a minimum pipe size of eight (8) inches for sanitary sewers in residential areas. There are very limited pipe sizes below six (6) inches. City terrain naturally flows northerly towards the Bay.

The Sewer Division crew completing Utility jet flushing crew makes note of excessive grease/build-up or blockage in any segment of the collection system. The information is then referred to the FOG Program if it appears that any food service establishment may be contributing to the issue. This may trigger a FOG investigation in the area. The City does not have large commercial processes that produce chronic FOG problems. FOG, when found, is typically localized in nature to onsite customer laterals.

CityUtility block book maps and customer service requests from upstream discharges can be evaluated to locate areas of concern. The area upstream of the grease build up is evaluated for potential sources, and Grease Removal Device cleaning and maintenance records are reviewed.

Enforcement action is taken against establishments determined to be causing grease blockages in the sanitary sewer, and additional requirements for cleaning or installation of Grease removal device (GRD) can be imposed.

The City is not located in a coastal flood zone, but does feature creeks through City limits, and has potential to experience larger than expected storms. The City currently plans capacity around a 10-year storm event, or 100-year storm event if near a storm drain pump station, consistent with the previous and in-progress Sanitary Sewer Master Plans and capacity studies. In addition, the Utility has continued coordination with SCVWD regarding flood protection and levees to mitigate potential flooding from surface waters within City limits. The Utility plans to continue tracking industry guidance on potential vulnerabilities to direct or indirect effects of climate change and adjust procedures accordingly.

8.2 Capacity Assessment and Design Criteria

The City of Santa Clara’s Design Criteria has been addressed in Element 5: Design & Performance Provisions.

The City of Santa Clara Sewer Capacity Assessment was completed in 2007 and updated in 2016; both reports are attached as Appendix J. The City is currently in the process of developing its Sanitary Sewer Master Plan, which includes the development of an “all-pipes” model, revised system-wide capacity studies, and an updated Capital Improvement Program. The Sanitary Sewer Master Plan is expected to be completed by the end of 2025 and before the next Sewer System Management Plan Update, and revised findings will be described in the next Sewer System Management Plan. For reference, a draft of the in- progress Sanitary Sewer Master Plan is included as Appendix J.

The major flow contributors to the sanitary sewer collection system have been identified. Lists of major dischargers are updated on a monthly basis and are listed in the table on the following page.

8.3 Prioritization of Corrective Actions

Defects identified through condition assessment are reviewed by Utility staff and used to prioritize repairs.

Severity of defect, defect type, size of pipe, location of pipe, and previous maintenance hi story are considered. Point repairs are completed on an as-needed basis by Sewer Division crews, and the Utility implements an annual sewer repair project to be completed by contractors to repair high priority assets where the scope of the repair exceeds that which can be completed by Sewer Division crews (i.e. large diameter trunks, pipelines with defects to large or too frequent to be addressed by point repairs, locations where intensive traffic control is needed). Historically, the annual repair project has addressed severe defects in large diameter (33-inches to 48-inches) sewer trunks with significant tributary sewershed.

Sewer System Management Plan
City of Santa Clara Water & Sewer Utility
52 The Public Works’ Engineering Department is responsible for managing the Public Works’ portion of the City’s Capital Improvements Program, which includes Sewer capital improvement projects.

If major deficiencies warranting rehabilitation or replacement of sewer system components are identified as a result of routine main-line cleaning or CCTV inspections that require resources beyond those available to the Sewer Division, the Assistant Sanitary Sewer Superintendent contacts the Principal Engineer – Water and Sewer. Principal Engineer then prioritizes and coordinates with Public Works Design Division for contracting the sewer main repair activities.

The City completed a Sewer System Capacity Assessment in 2007 and a General Plan Update in 2010 for new planned development and redevelopment. An update to the Sewer System Capacity Assessment was completed in 2016. Several capacity-related capital improvement projects were identified as a result of this assessment and have since been incorporate d into the City’s Capital Improvement Program. The current schedule for these projects is shown in Table 8-

2. Sewer Revenue from rates will be used to fund these projects.

PROGRAM MODIFICATIONS
Performance Measures
The City of Santa ClaraUtility will use the following measures to assess the performance of the collection system and the effectiveness of its SSMP:
• total number of SSOspills;
• number of SSOspills by each cause (roots, grease, debris, capacity, pipe failure, pump station failures, and other);
• portion of sewage contained compared to total volume spilled; • volume of spilled sewage discharged to surface water; and • planned to actual performance for preventivepreventative maintenance.

Implementation and Effectiveness
The CityUtility implements all elements of this SSMPthe SSMP and has been effective in minimizing SSOspill occurrences.

Preventative Maintenance Program
The City of Santa ClaraUtility’s preventative maintenance program has been utilized for many years and has resulted in a low number of SSOspills as indicated by Figure 9-1 below.

Performance Monitoring and Program Changes
The City of Santa ClaraUtility will evaluate the performance of its wastewater collection system at least annually using the identified performance measures. The CityUtility will update the data and analysis in this section at the time of evaluation. The CityUtility may use other performance measures in its evaluation. The CityUtility will prioritize its actions and initiate changes to this SSMPthe SSMP and the related programs based on the results of the evaluation.

SSOSpill Trends: Frequency, Location, and Volume
The CityUtility maintains records on SSOspills for 5 years. Figure 9-1 shows the frequency and volume of SSOspills by from Calendar Years 202012-202419 Table 9-1 shows SSOspill causescauses, and Figure 9-2 displays the location of SSOspills within the City of Santa Clara.

From this data, it is apparent that the CityUtility experiences low SSOspill rates.

Requirement: The City shall:REQUIREMENTS
