Element 1 – SSMP Goal and Introduction
City of Fairfield Sewer System Management Plan, April 2025 1
1.0: Element 1 – SSMP Goal and Introduction
SWB Requirements:
The goal of the Sewer System Management Plan ( SSMP) is to provide a plan and schedule to:
(1) properly manage, operate, and maintain all parts of the Enrollee’s sanitary sewer system(s), (2) reduce and prevent spills, and (3) contain and mitigate spills that do occur.
The Plan must include a narrative Introduction section that discusses the following items:
a. Regulatory Context
b. Sewer System Management Plan Update Schedule
c. Sewer System Asset Overview
1.1: Regulatory Context
This Sewer System Management Plan ( SSMP) describes the City of Fairfield’s (City’s) wastewater collection system management activities . The purpose of these activities is to:
1. Maintain and improve the condition of the collection system infrastructure,
2. Control infiltration/inflow (I/I) and provide appropriate sewer capacity, and to
3. Minimize the number and impact of sanitary sewer spills that occur.
The State Water Resources Control Board (SW RCB) has previously issued statewide waste discharge requirements for sanitary sewer systems which include requirements for development of an SSMP . The State Water Board requirements were outlined in Order No. 2006-0003-DWQ, Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, dated May 2, 2006 ( SWB SSO WDR) and the Monitoring and Reporting Plan (MRP) WQ 2013-0058-Exec. These two SWB requirements were replaced on December 6, 2022, by SWB Order WQ 20 22-0103-DWQ Statewide Waste Discharge Requirements, General Order for Sanitary Sewer Systems, which became effective on June 5, 2023.
1.2: Sewer System Management Plan Internal Audits and Update Schedule The reissued WDR for sanitary sewers define s new requirements for the auditing and updating of the enrollees SSMP including the preparation of internal audits of the SSMP. Audits must be completed, and an Internal Audit Report prepared covering a three-year period ending May 2, 2024. The Audit Report must then be completed, certified, and uploaded to the CIWQS system no later than November 2, 2024. Upon completion of the audit , the City must update the SSMP along with readoption by the City Council no later than May 2, 2025.
The next three-year audit period covers the period from May 3, 2024, thru May 2, 2027. The Internal Audit R eport must be completed, certified, and uploaded to CIWQS not later than November 2, 2027. Thereafter the internal audits shall be competed every three years on the same schedule irrespective of the last SSMP adoption date . The first SSMP revision under the Element 1 – SSMP Goal and Introduction
City of Fairfield Sewer System Management Plan, April 2025 2 reissued WDR shall be publicly considered and approved by the City Council and uploaded and LRO certified in CIWQS no later than May 2, 2025. Thereafter the updates must be completed every six years from May 2, 2025. Failure by the City in complying with the new audit and SSMP schedules requires the City to update the CIWQS system, notify the RWQCB with a justification for the failure to the timely submit the audit or SSMP and a schedule for the completion of the audit or SSMP. This does not change the required future schedules.
1.3: Sewer System Asset Overview
The City of Fairfield, located in Solano County, California, serves an estimated population in 2023 of 120,768 through approximately 22,900 service connections in a 41.4 square mile service area. The City manages 280 miles of gravity sewers, and approximately 5,581 manholes. The City does not own or operate any lift or pump stations in the City gravity sewer system. In addition, the City has the responsibility for an estimated 181 miles of lower laterals from the property line to the connection with the City’s mainline sewers.
FSSD and the City of Fairfield jointly operate and maintain the wastewater collection system that serves the City. FSSD owns and operates the trunk sewer system, which includes all 12 - inch and larger sewers and the major pump stations and force mains that convey wastewater to the FSSD’s wastewater treatment plant . FSSD also owns, operates and maintains all but one of the pump stations in the City’s wastewater collection system . The City, along with Suisun City and Travis Air Force Base, are “satellite collection system s” to FSSD, and the City owns and operates only those 10 -inch and smaller gra vity sewers within its service area . The City’s portion of the system consists of approximately 280 miles of gravity sewers . The City’s WDID number (2SSO10134) can be used by the City Council, customers or anyone interested in obtaining specific informatio n regarding the City’s record of sewer performance .
Intro Tables 1 to 5 below provide specific information regarding the gravity sewer pipes maintained by the City of Fairfield and the breakdown of service connections in the City .
A map of the City’s sani tary sewer system service area is displayed below .

Element 4 – Operations and Maintenance Program
City of Fairfield Sewer System Management Plan, April 2025 15
4.0: Element 4 – Operations and Maintenance Program
The Sewer System Management Plan ( SSMP) must include the items listed below that are appropriate and applicable to the Enrollee’s system:
a. Updated map of the sanitary sewer system,
b. Preventative Operations and Maintenance
c. Training
d. Equipment Inventory
4.1: Collection System Map
The City of Fairfield’s Infrastructure File is maintained as a Geograp hic Information System (GIS) database that provides a detailed and comprehensive representation of the sanitary sewer collection system. This GIS platform serves as a centralized repository for asset management, planning, and operational needs, ensuring ac curate, up-to-date information is readily available to both field and office staff.
City of Fairfield Water Distribution Operators have 24/7 access to the GIS database through their city-supplied cell phones, ensuring they always have access to this critic al information, whether responding to emergencies in the field or performing routine maintenance.
Key Features of the GIS Infrastructure File:
1. System Mapping and Asset Inventory:
o Interactive maps displaying the location and attributes of key assets, includ ing sewer pipelines and manholes.
o Layers for additional features, such as easements, parcel boundaries, and flow paths.
2. Asset Attributes:
o Pipelines: Material type (e.g., PVC, VCP), diameter, pipe ID, and length of section.
o Manholes: Object ID, node identification, installation date, rim elevation, and manhole depth.
3. Critical Sewer Assets Identification:
o Highlighted assets critical to system performance, such as main trunk lines, large-diameter pipes, and assets serving critical facil ities. o Risk-prioritized mapping to identify high -priority areas for inspections, repairs, and rehabilitation projects.
Element 4 – Operations and Maintenance Program
City of Fairfield Sewer System Management Plan, April 2025 16
4. Emergency Response Information:
o Quick-reference maps that provide essential information during emergencies, such as spills, help staff qu ickly understand the situation and determine the best course of action for remediation.
o Key isolation points, emergency bypass routes, and critical access points to support immediate response and control efforts.
Operations and Maintenance: Supports field crews by providing precise asset locations and relevant maintenance history With access to GIS via city -supplied cell phones, Water Distribution Operators can view asset locations, emergency procedures, and system attributes in real-time, improving their a bility to address issues efficiently and accurately . The City is also responsible for the operations and maintenance of the storm drainage and storm water conveyance assets in the service area. The City GIS includes the same information available to the staff as the sanitary sewer assets. In addition, City has created a separate GIS layer for all waters of the state inside the service area. This information is available in the field for use during responding to a sewage spill.
All mapping information is ava ilable to field staff on laptops in the vehicles in the field during all operations and emergency responses impacting either sewer assets. The GIS is currently maintained by City IT staff. When City field crews discover incorrect or missing data, working copies of the paper GIS maps are marked up and sent into IT to be updated . For new, replaced, or rehabilitated sewers constructed by the City, record drawings from the City’s Engineering Department are conveyed to IT and updated maps are provided electronic ally in a timely manner.
4.2: Preventive Operation and Maintenance Program
The elements of the City’s sewer system O&M program include:
Proactive, preventive, and corrective maintenance of gravity sewers and lower laterals ; Ongoing CCTV inspection program to d etermine the condition of the gravity sewers; Rehabilitation and replacement of sewers that are in poor condition; and Periodic inspection and preventive maintenance for the lift station
4.2.1: Prioritized Preventive Maintenance
The City proactively cleans the majority of its gravity sewers every 6 years . The historical calendar year results of the line cleaning performance of gravity lines is shown in Table 4 – 1:
Historical Line Cleaning Summary. A subset of the City’s sewers is cleaned more frequently as part of the City’s preventive maintenance program . “Problem area” sewers that require more frequent maintenance are placed on 4 -month, 6-month, or 12-month cleaning frequencies. Currently, approximately 45,995 feet ( 3.4% of the City’s collection system) of Element 4 – Operations and Maintenance Program
City of Fairfield Sewer System Management Plan, April 2025 17 “problem area” sewers receive more frequent maintenance . The basis of selection for these sewers includes:
“Blind” areas where a spill could potentially go unnoticed for long periods. “Critical” areas where the impact of a spill could be very significant. Areas that have experienced recurrent spills.
Areas in which roots and/or Fats, Oils, and Grease (FOG) are a problem. Areas identified through CCTV
The City’s sewer GIS loaded onto IPADs and/or laptops are used by field crews to identify the gravity sewers on 4-month, 6-month, or 12-month cleaning frequencies. The City will evaluate and refine the frequencies at which sewers are cleaned in order to achieve an optimal balance between high - and low-frequency cleaning using CCTV equipment and/or observations from cleaning.
The City‘s field crews perform preventive maintenance and correct problems identified during sewer cleaning or CCTV inspection . City field crews perform sewer cleaning with combination high velocity cleaning equipment (i.e., with the City’s Vac Con units). Staff will use ratings to determine frequency of cleaning, future CIP and immediate lower lateral replacement. In addition, the staff will quantify the cleaning results utilizing Supplement IV- A below.
4.3: Scheduling & Documentation
The City uses Mainstar, a computerized maintenance management system (CMMS) that tracks collection system preventive maintenance . Following gravity sewer preventive maintenance work, field crews fill out appropriate log sheets that identify the lengths and locations of the work performed; the log sheets are then used to record the information into the City’s CMMS .
Following lateral preventive maintenance, the street address of the lateral and any associated work orders (which are only generated if an emergency call -out is made) are logged in the CMMS.
Table 4 – 1: Historical Line Cleaning Summary provides the hot spot pipe cleaning information of all pipes included in the program as of December 20 20. Pipes are added to the hot spot cleaning program based upon results of the cleaning operations that have identified fats, oils, or grease as a problem, results of CCTV inspections, or as a result of a spill that is caused by FOG. The pipe segment remains o n the hot spot list until three successive cleaning results are clear or light as defined in the Supplement IV-A. The Annual Historical Line Cleaning since 2013 is also displayed in Appendix E under the Operational Performance section.

4.4: Manhole Inspections
The City conducts inspections and condition assessment of all manholes in the system at least every (10) years. The manholes are assessed using the MACP condition rating criteria by NASSCO. These ratings result in the development of necessary improvements and prioritized capital renewal and replacement in the five -year capital program In participation with the FSSD, the City uses a standard manhole inspection procedure for identifying the condition and defects in manholes, as well as a form to record the observations. The City and FSSD use the NAASCO MACP codes and procedures for this purpose.
4.5: Root Foaming
The City rarely contracts for root foaming from the results of the cleaning program, CCTV condition assessment and/or manhole inspections. These decisions are determined by sewer Element 4 – Operations and Maintenance Program
City of Fairfield Sewer System Management Plan, April 2025 19 program management and done when normal cleaning or root cutting cannot free the lines of roots or when manholes are found to be encumbered with root intrusion.
4.6: Siphon Maintenance
The City owns and maintains two (2) sanitary sewer siphons in the system . These assets are detailed in Table 1 – 4: Siphon Asset Information in Element 1. The City maintenance of two of these assets is scheduled along wi th the normal cleaning of sewer lines while the other is currently included in the four (4) month hot spot program cleaning.
4.6.1: Corrective Maintenance/Point Repairs
System defects, as identified, are documented and prioritized in the City’s computerized maintenance management system (CMMS) . Based on project size and complexity, City staff and/or private contractors are issued work orders to repair/replace the identified deficiency .
Where short sections of pipe have been identified as defective, City crews may insert pipe liners into the affected pipe segments; rehabilitating the pipe to near new conditions. The City staff also makes infrequent repairs found in the system from condition assessment of cleaning results.
4.6.2: SMART Covers
The City has one (1) smart cover deployed at a strategic location s in the City to alert on -call staffing and mangers of high levels in the collection system. The location s have been identified as location s suspectable to grease and /or root build up or areas to monitor for high discharge from industrial users .
4.7: Sewer Laterals
The City is responsible for the operations and maintenance of the lower laterals that connect to the private upper lateral from residences and buildings . These lower laterals are currently estimated to be 181 miles of laterals. The City performs lateral preventive maintenance (PM) if a right-of-way cleanout exists at the property line . To date, lateral PM has focused primarily on more sensitive and/or critical areas within the City (e.g., older neighborhoods, areas with root problems, Orangeburg upper laterals, etc.), but has been expanded to include other areas as needed. The City has one dedicated crew for lateral maintenance. Lateral preventive maintenance is typi cally performed using an electric rodder with a 4 -inch cleaning head. Each lateral will be inspected with CCTV prior and post cleaning. Each lateral is rated and is given a rating on the following items; roots, grease, cracks, sags, offsets . Table 4 – 3: Lower Lateral Historical Line Cleaning Performance , below provides an historical perspective to the effort of the lateral crew for the maintenance of the City maintained lower laterals. The Annual Lower lateral Cleaning since 2013 is also displayed in Appen dix E under the Operational Performance section.

6.1: Existing Documentation
The City, pursuant to the reissued WDR, completed and updated the original Overflow Emergency Response Plan to a Spill Emergency Response Plan (SERP). The SERP includes Element 6 – Spill Emergency Response Plan
City of Fairfield Sewer System Management Plan, April 2025 28 all new requirements and the revised sampling and testing requirements formally contained in the City‘s earlier 2013 Water Quality Monitoring Plan.
6.2: Purpose
The purpose of the City of Fairfield Spill Emergency Response Plan (SERP) is to support a prompt, orderly and effective response to spills (sanitary), reduce spill volumes, and collect information for prevention of future spills. A “spill” in this document is defined, by State Water Board Order No. WQ 2022 -0103-DWQ as 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.
The SERP provides guidelines for City personnel to follow in respondi ng to, cleaning up, reporting, and properly documenting spills that may occur within the City’s service area. This SERP satisfies the State Water Board Order No. WQ 2022 -0103-DWQ, which require wastewater collection agencies to have a Spill Emergency Respo nse Plan.
Additionally, the SERP outlines procedures for responding to sanitary sewer spill backups into structures as required by the City’s insurer. See definitions. “Backup” is a term typically used by insurers to describe property damage resulting from exposure and contact to untreated or partially treated sewage.

Element 7 – Sewer Pipe Blockage Control Program
City of Fairfield Sewer System Management Plan, April 2025 31
7.0: Element 7 – Sewer Pipe Blockage Control Program
The Sewer System Management Plan must 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:
a. An implementation plan and schedule for a public education and outreach program that promotes proper disposal of pipe -blocking substances;
b. 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 t o adequately dispose of substances generated within a sanitary sewer system service area;
c. The legal authority to prohibit discharges to the system and identify measures to prevent spills and blockages;
d. 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; e. Authority to inspect grease producing facilities, enforcement authorities, a nd whether the Enrollee has sufficient staff to inspect and enforce the fats, oils, and grease ordinance;
f. An identification of sanitary sewer system sections subject to fats, oils, and grease blockages and establishment of a cleaning schedule for each sec tion; and g. Implementation of source control measures for all sources of fats, oils, and grease reaching the sanitary sewer system for each section identified above.
7.1: Public Education and Outreach Program
The City has established a comprehensive outreach pr ogram for residential and food service establishment customers that includes brochures and newsletter inserts . The outreach materials will be included on the City’s pollution prevention webpage. The City also regularly includes information and sewage disch arge requirements in citizen newsletters especially around the end of the year holidays related to grease disposal requirements. The City has also identified areas in the collection system where grease spills have occurred and have enhanced the cleaning operations with more frequent cleaning.
The City has an active program of requirements and regular inspections for food service establishments assuring, thru regular inspections, that the grease interceptor infrastructure are operating properly and being reg ularly maintained as permitted.
Element 7 – Sewer Pipe Blockage Control Program
City of Fairfield Sewer System Management Plan, April 2025 32 The City currently has approximately 400 food service establishments (FSEs) within the service area. The City has by contract with FSSD authorized them to assist with the management, administration and enforcement of the FOG Source Control Program in the City of Fairfield. This effort is also coordinated by FSSD in the City of Suisun City and the unincorporated areas within the FSSD treatment plant service area . Finally, FSSD also manages the industrial waste permit program i n Fairfield.
Data regarding the nature and extent of the FOG problems in the Fairfield system was analyzed including the location of FOG -related service calls (which include blockages), FOG-related spills, frequent preventive maintenance, and food service establishments (FSEs) .
The City FOG Program results for the past twelve years shows a substantial reduction in FOG related overflows from 6 down to one per year in the past three years (see Appendix E) .

Element 7 – Sewer Pipe Blockage Control Program
City of Fairfield Sewer System Management Plan, April 2025 33
7.1.1: Fairfield Sewer System
The City experienced three FOG-related spills in CYs 2021 through 2024. FOG-related spills occurred in both commercial and residential areas . From Table 7 – 1, the frequency for inspection of all FSE is approximately every two years and results in an average of 24% requiring some level of enforcement following the inspection.
7.2: Summary of FOG Data Analysis
The analysis of spills, FSE, and frequent maintenance lines shows that FOG is a factor in the City, but the current FOG Source Control Program and the preventive maintenance programs have been effective at reducing the frequency of spills (see Appendix E Number of Overflows by Cause). The ongoing FOG-related problems are associated with high density residential and, to a lesser extent, low -density residential sources.
7.3: FOG Source Control Program Approach
Normal maintenance is to CCTV and clean once every 5 -years; cleaning is not necessary if CCTV shows no debris in the line. A “hotspot” is part of the sewer system prone to problems and requiring higher frequency maintenance. Determining hotspot maintenance frequency requires professional judgment and takes into consideration pipe size, flow, severity of grease, debris or defect. An area of grease build -up can be kept to a minimum with increased cleaning frequency resulting in spill prevention and less cleaning effort for the next cycle.
Hotspots are evaluated annually to determine the frequency of cleaning necessary to prevent future blockages. The frequency of cleaning may be increased or decreased by the supervisor based on the CCTV observations, feedback from cleaning crew and the condition of sewer line. Occurrence of a subsequ ent SPILL will result in more frequent cleaning. Locations may be removed from the hotspot list by the supervisor if two consecutive cleanings show that there is little potential for a future blockage. The City of Fairfield use s a spreadsheet and GIS maps to manage hotspot locations and cleaning frequencies.
FSSD has expanded the scope of the FSE storm-water inspection contract with the County to include collection information on restaurant grease handling practices throughout the service areas of the thre e agencies. The County inspections provide data that is used in outreach to FSEs. The goal of the inspections is to expand agency understanding of restaurants’ grease management practices, increase FSE awareness and improve GRD maintenance practices to reduce FOG. Inspection data is used to analyze the practices of problem FSEs and to develop strategies to educate and improve FSE grease handling practices.
FSSD and Fairfield practice focused outreach with the use of door hangers and kitchen grease scrapers for residential sources and inspection/education for commercial sources. The combination of focused outreach and preventive maintenance of hotspots has achieved desired reduction in FOG related SPILLs.
Element 7 – Sewer Pipe Blockage Control Program
City of Fairfield Sewer System Management Plan, April 2025 34 FSSD and the City will continue the FOG Source Contro l Program. The responsibilities of each agency for the elements of the FOG Source Control Program are shown below in Table 7 – 2: FOG Control Program Activities and Responsibilities .

7.4: Public Outreach Program
FSSD, Fairfield, and Suisun City currently manage FOG -related problems with focused outreach and preventive maintenance. City and FSSD crews’ hand outdoor hangers with information on proper FOG disposal to residents or neighborhoods that have experienced a FOG-related buildup, blockage or SPILL. Residential SPILLs caused by FOG have decreased by 50 percent since 2005 .
7.5: Acceptable FOG Disposal Facilities
FSSD maintains a list of haulers and disposal facilities that serve the service area. The FSE inspections incl ude collecting data on which haulers are used. The information is used to help FSEs properly manage FOG
A list of facilities in the San Francisco Bay Area that accept grease from grease haulers is included as Supplemental VII-A. The list will be provided t o commercial grease haulers regularly working within the service area. Lists of grease haulers approved by the East Bay Municipal Utility FSSD (EBMUD) and the Sacramento Regional County Sanitation FSSD (SRCSD) are included as Supplemental VII-B and VII-C.
7.6: FOG Inspections
Solano County is responsible for regular inspections of FSEs inside the City. The results are reported to both the City and FSSD and appear in Table 7 – 2 above, which provides a twelve-year history of both inspections and violations.
7.6.1: FOG Legal Authority
Legal authority is established in FSSD’s Wastewater Discharge Ordinance (Ordinance) . The Ordinance is applicable to all users of the Publicly Owned Treatment Works (POTW). The definition of POTW includes, but is not limited to, systems in t he FSSD service area that collect and convey wastewater to the POTW including City owned sewers and laterals; see section 1.4 MM of the Ordinance . Section 2 of the Ordinance addresses collection system illicit discharges and other discharge prohibitions .
7.6.2: Staffing
FSSD, County Health and the City provide the staffing required to administer, inspect and enforce the FOG program.
7.7: Requirements for Installation
Element 7 – Sewer Pipe Blockage Control Program
City of Fairfield Sewer System Management Plan, April 2025 36 FSSD’s Ordinance provides legal authority to require GRDs if necessary. FSSD provides information on BMPs to FSEs as part of outreach activities when needed. The City Building Departments require GREs on new restaurants. GREs are designed per Uniform Plumbing Code.
7.7.1: Facility Inspections
FSSDs Ordinance provides the authority to in spect grease producing facilities and to enforce the ordinance. The Ordinance applies to District and city sewers. The District has contracted with the County to expand health inspections to include FSE grease management.
7.7.2: Investigation and Enforcement
FSSD and the City will work together to identify FSEs that cause FOG -related blockages or SPILLs. FSSD conducts facility inspections to determine the source of the FOG in these instances.
FSSD and the City will initiate enforcement action against FSEs in thei r service areas that are determined to be in violation of the requirements of the FOG Control Program . Enforcement actions may include a verbal warning, a written warning, administrative orders (which may include fines), and possibly disconnection from the public sewer system. During the period from January 2015 through 2017 eighteen (18) enforcement actions of the FOG Program regulations were found to be necessary.
7.8: FOG Section Subject to FOG Blockages
FSSD and Fairfield have identified sewer sections subje ct to FOG blockages (hotspots). Each agency has developed a cleaning frequency for hotspots to prevent spills from occurring.
Based on the analysis of data collected during expanded FSE inspections and additional CCTV work, sewer cleaning frequencies, and structural repair activities are continually updated to minimize FOG -related blockages and spills . Additional source control measures are not necessary at this time.
7.8.1: Design Standards, Plan Review, and Inspection
FSSD and the City have developed common spec ifications for the installation and sizing of GRDs. The City is responsible for reviewing proposed development plans to ensure that they address the installation of GRDs . The City has in place processes to ensure the GRDs are properly installed during new construction and remodels as part of its Building Inspection duties.
7.8.2: Maintenance Standards and BMPs
FSSD and the City have developed common standards for the proper maintenance of GRDs .
FSEs that discharge significant quantities of grease will be tracked u sing discharge permits administered by FSSD.
FSSD will encourage FSEs to employ BMPs as part of their efforts to control the discharge of FOG to the public sewer system . The BMPs that will be encouraged include:
Element 7 – Sewer Pipe Blockage Control Program
City of Fairfield Sewer System Management Plan, April 2025 37 Posting “No Grease” signs over sinks and dis hwasher; Collecting and recycling cooking oil;
“Dry wiping” pots, pans, and kitchen equipment before cleaning with proper disposal of the wipes and grease ;
Maintaining/cleaning grease traps on a regular schedule; Checking grease interceptor s on a regular schedule (grease and solids should not exceed 25% of interceptor depth);
Using absorbent paper under fryer baskets;
Using absorbent (such a rice hulls, cat l itter) to pick up oil and grease spills; and Not using emulsifiers or solvents other than dishwashing detergents.
FSSD activities will include the distribution of placards and literature promoting the use of BMPs and observations/comments will be provided during facility inspections to encourage the use of BMPs.
7.9: Record Keeping and Reporting
Solano County, FSSD and the City work together to update the list of FSEs in each service area regularly.

Element 8 – System Evaluation and Capacity Assurance Plan City of Fairfield Sewer System Management Plan, April 2025 41
8.0: Element 8 – System Evaluation and Capacity Assurance Plan
The Plan must include procedures and activities for:
a. Routine evaluation and asse ssment of system conditions; b. Capacity assessment and design criteria;
c. Prioritization of corrective actions; and
d. A capital improvement plan.
8.1: Routine Evaluation and Assessment of System Conditions
8.1.1: Scheduled Inspections and Pipeline Condition Assessment:
In order to implement a consistent, system -wide CCTV inspection program, FSSD purchased and operates two CCTV trucks on behalf of all three agencies (Fairfield, Suisun City and FSSD). The City coordinates with FSSD to inspect the entire collection system in a 5-year period. FSSD, on behalf of the City, began by inspecting approximately 20 percent (or approximately 285,000 feet) of the City’s uninspected sewers per year . Following the initial year’s inspection, FSSD continued by inspecting approximately 20 perc ent of the City’s remaining uninspected sewers each year until all sewers had been inspected . The historical summary of CCTV results by FSSD on behalf of the City are included in Table 8 – 1 below.
Sewers will be prioritized for inspection based on pipe ag e, material, location, criticality and maintenance history . Recently the City determined to have City staff conduct CCTV condition assessment of gravity sewer lines 10 inches and less. As a result, FSSD has provided previous CCTV condition assessment results to the City for use in developing capital plans. FSSD also has agreed to provide funding directly to the City for the CCTV work on a monthly basis into the City enterprise fund from the FSSD Operations Fund 1.
Following the baseline inspection, the freq uency of subsequent inspections will be based on the condition of the sewer during the initial CCTV inspection . The CCTV program will also include the inspection of sewers shortly after a blockage/stoppage event, in order to determine the primary cause of the blockage/stoppage so that appropriate action can be taken .
In conjunction with CCTV inspection and cleaning work, the City will conduct inspections of manholes. Similar to sewer inspections, the frequency of subsequent manhole inspections will be determined following an evaluation of the initial inspection results.
In 2022, FSSD in conjunctions with the City’s prepared a Collection System Asset Management Plan (CSAMP). The CSAMP guides the cost-effective maintenance, repair, and replacement of infrastructure assets owned and maintained by the City of Fairfield (Fairfield), City of Suisun City (Suisun City), and the Fairfield -Suisun Sewer District (FSSD/District).
The Agencies are transitioning out of a period of new construction and into long-term maintenance of their infrastructure. This CSAMP aligns the Agencies’ priorities and vision Element 8 – System Evaluation and Capacity Assurance Plan City of Fairfield Sewer System Management Plan, April 2025 42 for efficient, sustainable asset management into the future .
8.2: Television Inspection Codes
Tthe City uses a standard set of observation s and pipe material codes to identify the defects and materials observed during CCTV inspection of its collection system . The City and FSSD use the NAASCO PACP codes for this purpose . Future CCTV inspection records (inspection logs, video, and still photos) are reviewed by City staff to verify the observed defects and material classifications .
Table 8 – 1: Historical City CCTV Performance
Calendar Year Total, Linear Feet Total. Miles Percentage of System, 280 miles
2020 158,222 29.96 7.2%
2021 294,649 55.8 13.4%
2022 100,450 19.02 4.6%
2023 265,085 50.21 19.4%
2024 374,195 70.87 25.3%
Average 238,553 45.17 16.1%
8.2.1: Manhole Assessments
In participation with the FSSD, the City uses a standard manhole inspection procedure for identifying the condition and defects in City manholes, as well as a form to record the observations. The City and FSSD use the NAASCO MACP codes and procedures for t his purpose. The City conducts inspections and condition assessment of all manholes in the system at least every (10) years. The MACP condition rating criteria by NASSCO result in the development of necessary improvements and prioritized capital renewal an d replacement in the five-year capital program.
8.3: Capacity Assessment and Design Criteria
8.3.1: Hydraulic Analysis
As a part of the FSSD’s 2008 Master Plan, a hydraulic model was used to evaluate existing and future system capacity . The hydraulic model provides a realistic representation of changes in flow over time as well as estimates of surcharging and backwater effects due to capacity limitations. The section of the Master Plan report called “System Analysis Methodology” provides a detailed discussion of the mo del development and use of the model to identify capacity deficiencies and needed improvements. In 2018, FSSD completed an update to the 2008 Sewer Master Plan for current pipe systems owned and operated by FSSD and the two City’s. City sewers with observ ed wet weather capacity deficiencies were added to the FSSD’s model as needed.
Element 8 – System Evaluation and Capacity Assurance Plan City of Fairfield Sewer System Management Plan, April 2025 43 Based upon pipe condition ratings performed by FSSD, the City has evaluated and prioritized needed replacement projects in the midtown areas of the City in the Midtown Sewer Placement Project . This project has identified five separate high priority areas for sewer rehabilitation and replacement based upon condition ratings, age of the pipes in this area, staff field observations and historical performance. These projects have been been completed or included in the City Capital Improvement Program for the next five years . These projects did not identify any capacity related issues in the City owned pipelines in the Midtown project area.
Through its master planning efforts, FSSD has estimated the City’s wastewater flows based on land use information provided by the City . Wastewater flow was estimated separately for three components: sanitary base flow, including land use -based sanitary flow and point flow sources; wet weather infi ltration (groundwater infiltration); and storm -related infiltration and inflow. These estimates were calibrated to historical wastewater flow monitoring data collected by the FSSD.
Existing and future dry weather flows and peak 5 -, 10-, and 20-year design storm flows were developed. The design storms are 24 -hour events based on historical rainfall intensity -depth- duration statistics for the Fairfield -Suisun area as documented in the Solano County Water Agency Hydrology Manual .
The same basis of flows will be used for the capacity assessment of the City’s sewer facilities that may be identified for inclusion in the hydraulic model based on the criteria noted in the section above.
The City’s sanitary sewer design criteria included in the City’s 2017 Standard Specifications Section 5 is used to evaluate the size of sewers needed to serve new development. This same criterion will be used to evaluate the adequacy of existing sewers, as necessary. If it becomes necessary to model existing sewers with questionable capacity, FSSD’s model and design storm criteria will be used.
8.3.2: Prioritization of Corrective Actions
The 2022 CSAMP used a business risk exposure (BRE) assessment process for the prioritization of capital and renewal and replacement projects. The risk assessment process utilized rankings for likelihood of failure and likelihood of consequences to prioritize each of the projects identified in the CSAMP. The BRE score builds off the results of an asset’s condition assessment to develop its likelihood of failure (LOF) and consequence of failure (COF). Each of these criteria are ranked and the scores are then multiplied together to set the BRE for the asset. The BRE score is then used for both maintenance operations and to establish capital project priorities.
These priorities are then annually reviewed in putting together the final capital plan for each agency including any new operational information or changes in the BRE.
Element 8 – System Evaluation and Capacity Assurance Plan City of Fairfield Sewer System Management Plan, April 2025 44
8.3.3: Capital Improvement Program (CIP)
Sewer condition and capacity data are used during th e preparation of the City’s annual CIP Budget and its multi -year CIP. To reflect similar refinements to the City’s rehabilitation and replacement program, the City’s CIP will be refined annually following the first year of the City’s baseline CCTV inspecti on program. In addition to rehabilitation and replacement projects, the City’s CIP will address any needed capacity improvement projects, which are discussed in Element VIII (Capacity Management) of this SSMP . The City annual capital project requests are s ubmitted to FSSD and included in their annual capital budget for FSSD Board approval. FSSD per agreement with the two Cities, has created a separate City Collections System Reserve. Each capital project submitted by the City includes projections of capital needs for the future five years. Annually, FSSD deposits into the City Collections Reserve Fund at FSSD the prioritized value of projects from CSAMP that were included in the CSAMP. Currently the City received $1.83 million annually.
8.3.4: Annual CIP Budget
The biannual Capital Improvement Program (CIP) budget includes increases in pipe size, I/I reduction programs, Grade 4 & 5 pipe failures repairs, increases and redundancy in pumping capacity, and storage facilities . The City has put into place the steps ne eded to establish short - and long-term prioritized capital projects to address identified hydraulic deficiencies, including prioritization, alternatives analysis, and schedules. Future prioritization will include increased recognition of the importance of f ailures resulting from spills that are within 1000 - feet of the river and its tributaries.
The City has prepared and implemented the CIP and project schedules that will provide hydraulic capacity of key sanitary sewer system elements for dry weather peak flow conditions, as well as the appropriate design storm or wet weather event . The CIP includes implementation schedule s and identifies sources of funding for each project .
Per agreement with FSSD, the City annually by August 1st receives capital requested funds from Fairfield’s Collection Systems Reserve fund at FSSD. The City then completes the approved projects during the year. At the end of the year, and as part of the new budget, the two agencies “true up” the funds in that budget.
8.3.5: Cyclic Replacement Program
The City’s current rehabilitation and replacement program is based on the results of prior CCTV inspections as well as more recent City CCTV inspection information from investigation of spills. The City uses the results of the baseline CCTV inspect ion program described above to develop its future rehabilitation and replacement program . As additional CCTV inspection data is gathered during subsequent fiscal years, the program will continue to be refined to address the highest priority sewers first.
Element 8 – System Evaluation and Capacity Assurance Plan City of Fairfield Sewer System Management Plan, April 2025 45 The biannual Capital Budget currently includes two projects – the Midtown Sewer Replacement project and the West Texas Relief Sewer to be designed, built and completed through fiscal 2027 .
8.3.6: Project Funding
FSSD and the two cities are all responsible for pro ject funding from sewer service charges and grants and loans. The Cities have contracted with FSSD to serve as the for funding management and investments. Each City has a separate Collection System Reserve Fund that holds all deposits identified in the CSA MP for capital projects. FSSD regularly conducts sewer service charge studies on behalf of the three agencies providing 5 -year rate schedules that includes all operations and maintenance, capital requirements and full management of the sewer rate collectio n processes. Once the rates are adopted and effective, the two cities include the sewer rates on each of their water bills. The sewer revenues collected each month are then transferred to FSSD and are deposited into the FSSD Operations Fund . Then FSSD returns the rate developed funds for operations back to the City each month. Once the FSSD capital budget is approved, FSSD annually transfers funds specified in the CSAMP by August into the City’s Sewer Enterprise Fund . At the end of the fiscal year, any overspent or underspent from fiscal year payments are reconciled with the future budget allocations.
The City generally relies on sewer service charges and sewer fund reserves to fund the biennial capital program work . The City has recently accepted a $3.1 million federal grant to partially fund the West Texas Relief Sewer. The biennial Capital Improvement Program provides a summary of the proposed projects for five year along with a summary and description and funding for each individual project. The C ity, every two years, considers changes and revisions to the four-year plan based upon condition assessments and operations results to prioritize and update the improvement plan. The City also relies on Sewer Rate Studies to determine the funding methods t o be used for the program, typically on a five -year basis.
8.3.7: Joint Coordination
The City staff from both Engineering and Operations Divisions regularly meet to discuss and develop the capital program priorities and to review changes and funding required for any changes proposed in the future Capital Budget. The City Council considers and adopts a biennial Capital Budget and then regularly considers mid -year correction for new and critical projects that may require changes in the CIP.

9.0: Element 9 – Monitoring, Tracking and Reporting
System
The Plan must include an Adaptive Management section that addresses Plan -implementation effectiveness and the steps for necessary SSMP improvement, including :
a. Maintain relevant information , including audit findings, to establish and prioritize appropriate Plan activities;
b. Monitor the implementation and measuring the effectiveness of each element of the Plan;
c. Assess the success of the preventative maintenance activities; d. Updating Plan procedures and activities, as appropriate, based on monitoring and performance evaluations; and
e. Identifying and illustrating spill trends, including spill frequency, locations, and estimated volumes .
9.1: Adaptive Management:
The City regularly tracks and updates the performance results of the sanitary sewer program and reports the findings in the Annual City Council Sewer Report and in March of each year to the CIWQS database in the review Annual Report . In addition, the SERP is also reviewed for effectiveness and any changes are made to assure proper and timely responses prior to the annual report certification requirement. The City also pursues and evaluates the SSMP Au dit Report corrective actions to determine when and how t he program should be modified and changed. Finally, the sewer program uses the historical performance results, post spill assessments and operation and maintenance results during the development of the Annual Sewer Report to assess the need for further ada ption of the program to reduce spills to Waters of the State and to review and consider implementing technology changes to further improve operations of the program. All modification and changes to the SSMP are then included in the SSMP Change log.
9.2: Effectiveness
The effectiveness of each SSMP element is measured through the use of selected performance indicators. These indicators are tracked and reported regularly and include the annual performance requirements in the SSMP Annual Report submitted to the CIWQS system.
Performance indicator data are incorporated into historical graphs presented in Appendix E attached. Some of the historical performance indicators tracked includes the following:
Total number of spills (from gravity and lower laterals) Number of Spills by Category
Element 9 – Monitoring, Tracking and Reporting System
City of Fairfield Sewer System Management Plan, April 2025 48 Number of spills for each cause (roots, grease, debris, pipe failure, capacity, pump station failures, and other);
Portion of sewage contained /recovered compared to total volume spilled ; Volume of spilled sewage discharged to surf ace water Number of owner owned/operated lateral spills
Selected operational performance results .
The City also maintains the following metrics for the operations and maintenance of the sewer collection system .
Annual line and lower lateral cleaning, linea r feet
Annual CCTV, linear feet
Annual cleaning, percentage of the system
Annual CCTV, percentage of the system
9.3: Assess Success of Preventative Maintenance Activities Based on the above monitoring and performance evaluations and historical graphs , the two audit reports and any changes identified in the SSMP Change Log, the elements of the SSMP will be updated or modified, as appropriate. At a minimum, the SSMP will be updated every six (6) years and include any significant program changes. In accord ance with Subsection D.14 of the Order, the updated SSMP will be re -certified by the City Council and uploaded and certified by the City LRO into the CIWQS database .
9.4: Identify and Illustrate Performance Trends
The City regularly tracks both spill and opera tional indicators in tables that are used to create the graphs included in Appendix E. These graphs are used to assist in determining the effectiveness of the program and to compare the program results with RWQCB Region 5 and all enrolled agencies in the S tate. Trends from the various metric results are used to determine changes and adapt improvements in the program activities to assure continuing and improving effectiveness.
