3 ELEMENT 1: GOAL AND INTRODUCTION
1.1 Regulatory Context
The City of Santa Clara Water & Sewer Utilities Department (Utility) has prepared this Sewer System Management Plan (SSMP) to comply with the San Francisco Bay Regional Water Quality Control Board (RWQCB) and the State Water Resources Control Board (SWRCB) General Order 2022-0103-DWQ (see Appendix A). The SSMP is intended to:
• Provide sufficient planning, description of resources and direction for staff to maintain, manage and repair the Utility’s sanitary sewer collection and conveyance system such that all sewer flows delivered to the Utility’s system are conveyed safely to the publicly owned wastewater treatment plant (San José – Santa Clara Regional Wastewater Facility) without spills. • The SSMP includes actions to minimize the number and severity of spills and to help mitigate the impact of spills on the environment.
The SSMP supports and supplements the Utility’s existing operations and maintenance program and goals by providing consolidated guidelines and procedures for the Utility’s sewer system management. The SSMP will also contribute to the proper management of the collection system by memorializing these activities.
In addition, a sewer system capacity study has been performed and was updated in 2016 to determine any improvements needed to ensure the system has adequate capacity to convey all peak flows, for current and future development, including allowances for storm waters that may enter into the sewer system. The City is currently in the process of developing an update to 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 and recommendations will be included in the next Sewer System Management Plan. A draft of the in-progress report can be found in Appendix J.
REQUIREMENTS
The goal of the Sewer System Management Plan (Plan) is to provide a plan and schedule to:
• Properly manage, operate, and maintain all parts of the Enrollee’s sanitary sewer system(s),
• Reduce and prevent spills,
• Contain and mitigate spills that do occur.
The collection system agency must develop goals to properly manage, operate, and maintain all parts of its wastewater collection system
REQUIREMENTS
The Plan Introduction section must provide a general description of the local sewer system management program and discuss Plan implementation and updates. 4 1.2 Sewer System Management Plan Update Schedule
In accordance with Statewide Sanitary Sewer Systems General Order 2022-0103-DWQ, the current SSMP Update is due May 2, 2025, with subsequent updates every 6 years. The next SSMP Update will be due May 2, 2031.
The audit period for the next planned Sewer System Management Plan audit will initiate November 2, 2025, and be completed by May 2, 2028. The audit should be submitted to the California Integrated Water Quality System (CIWQS) and will provide coverage through November 2, 2028 (by 6-months after the end of the 3- year audit period).
In order to prevent spills within its service area, the Utility implements system-wide condition assessment using closed-circuit television (CCTV) and routine & scheduled preventative maintenance including inspection, jetting, and repairs. A summary of these activities to be completed during the future 6-year SSMP update cycle is listed below, and further documented in Element 4 (Operation & Maintenance Program):

City of Santa Clara Water & Sewer Utility
9 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:

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.
In December 2020, the Utility completed work to upgrade the core hardware, software, and network equipment supporting the Utility’s supervisory controls and data acquisition (SCADA) System. This SCADA upgrade was intended to provide a state-of-the-art SCADA system deployed on a fast, reliable, redundant, and secure fiber optic ring, and to provide increased functionality in sewer facility site monitoring and control. This upgrade included 2 new servers, 3 workstations and 4 client PC’s, as well as 8 new managed switches and 4 uninterruptable power supplies. The upgrade involved re-deploying the network over a newly installed, purpose-built, fiber optic ring, connecting key sites at the Corporation Yard SCADA building, the Corporation Yard Ops center, the Emergency Operations Center, and the Data Center at City Hall. The Utility also deployed a second Sewer System Management Plan
City of Santa Clara Water & Sewer Utility
10 antenna and master radio at the Corporation Yard to rectify a “single point of failure” problem that had previously existed on the Utility’s legacy radio network. As part of this SCADA upgrade, all sewer pump stations were upgraded and converted to the new fiber network.
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).

18 ELEMENT 4: OPERATION & MAINTENANCE PROGRAM
4.1 Updated Map of Sewer System
The Utility prepares and updates the sanitary sewer system maps (block books) continuously in CAD and/or GIS map and 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 Division operations and maintenance personnel.
The following information is included in current map books:
● force mains ● private mains
● manholes ● manhole numbers
● direction of flow ● flushing inlet
● laterals (with dimensions) ● depth of manhole
● diameter of mains ● pipe materials
● year pipe installed ● siphons
● lift stations ● pump stations
● chart station ● private systems
● other sewer mains (not City) ● distance between manholes
Since the block book itself constitutes more than one hundred pages it is only referenced in this document. Appendix D shows Index sheet for the block book for the Utility’s collection system.
REQUIREMENTS
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.

19 4.2 Preventative Operation and Maintenance Activities
Goals of the Preventative Maintenance Program
The main objectives of the preventative maintenance program are to:
• Maximize service life of the City’s sanitary sewer system • Avoid major failures of the system
• Minimize sanitary sewer overflows and backups
• Respond appropriately to customer concerns and requests.
Major components of the program are identified as follows:
• Prioritize cleaning and maintenance of sewer system components • Customer service
• Ongoing condition assessment
• Capital Improvement Program
• Staff training and providing adequate resources like combination cleaning trucks, CCTV cameras, etc.
• Maintenance of sanitary sewer system maps, equipment and supplies inventories
• Use of SCADA systems to monitor and control sewer facilities remotely. • Use of a computerized maintenance management system (CMMS) at any time to manage assets and track work orders for scheduled preventative 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 schedules for inspecting, cleaning, and servicing the Utility’s sewer system facilities and maintaining records of the work completed. The current SSMP documented here is an update and supersedes the previous SSMPs. The Utility strives to balance its strong emphasis on customer service with a comprehensive and efficient preventative maintenance program that prevents spills.
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.
The data collection system must document the data from system inspection and maintenance activities, including system areas/components prone to root-intrusion potentially resulting in system backup and/or failure.
Sewer System Management Plan

The Utility’s goal is to clean and inspect the entire length of their sewer system within 8 years.
This includes replacing deficient mains identified by the 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.
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 cleaning. CCTV videos and reports are uploaded and stored in the Utility’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.
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. The Utility utilizes a Computerized 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 data into the CMMS.
Routine Main Line Maintenance
The Utility records details of main line maintenance, including date, location, feet, findings, manhole assessment, television work, names of staff completing work, and other comments. An example of a data sheet printout from Lucity can be found in Appendix L.
Areas Needing More Frequent Cleaning (HFC’s or Higher Frequency Cleanings) The Utility 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 spills (Table 4-3). The typical causes for 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 or removed from the list as problems are resolved and new problems are identified.
Sewer System Management Plan
City of Santa Clara Water & Sewer Utility
22 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 used to revise 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. Siphons are inspected regularly and jetted as necessary. A list of siphons is located in Table 4-4.

28 The Utility also holds a contract with a private company to perform major pump maintenance or repairs due to the expertise and resources needed.
Root Control
As a part of a customer service request, the Utility may treat smaller mains for root control by means of physical removal or 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.
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
Manholes are inspected as mains are jetted. In this way, all manholes are inspected approximately once every 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 Sewer 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
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.

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 Maintenance Worker is dispatched to investigate the problem and resolve 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 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.
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 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 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. Utility workers try to respond to service calls within 30 minutes. The Sewer System Management Plan

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 according 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 can be more easily identified and resolved.
In Chapter 13.10 of the Santa Clara Municipal Code under 13.10.020 Definitions (S) (5) sewer 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.”
Sewer System Management Plan
City of Santa Clara Water & Sewer Utility
38 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 joints, 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.

40 establishment upon initial inspection and at any time deemed pertinent. These materials are available on the City’s website and are distributed by Utility staff as necessary. In addition, sewer crews may distribute notices in areas that have noted FOG “Hot Spots”.
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 companies. The Utility 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 Utility has 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 spill 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
41 Source Control Measures to Prevent Spills/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 jet flushing 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.
Utility 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 largest impact of climate change on the Utility’s ability to respond to issues in the sanitary sewer system are anticipated to be related to sea level rise and flood risk. 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.

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 history 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.
8.4 Capital Improvement Plan
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
REQUIREMENTS
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.
REQUIREMENTS
The capital improvement plan must include the following items:
(a) Project schedules include completion dates for all portions of the capital improvement program.
(b) Internal and external project funding sources for each project. (c) 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.

45 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. The current schedule for these projects is shown in Table 8-2.
Table 8-2: Sanitary Sewer Capacity Improvement Project
The capacity-related capital improvement projects documented above has not yet been constructed or scheduled into the City’s Capital Improvement Program. As previously stated, the City’s update to its Sanitary Sewer Master Plan is currently in-progress, and with the inclusion of an all-pipes model and significant changes to the previous studies development assumptions, the City elected to postponed previously identified capacity-related capital improvement projects until the current Sanitary Sewer Master Plan update can be completed. 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 Capital Improvement Projects will be described in the next Sewer System Management Plan.
The funding sources for the City’s Capital Improvement Plan for the Water and Sewer Utilities are derived from sewer rates, connection fees and bonding proceeds. A copy of the Sewer Utility Budget is attached in Appendix K.
