SSMP Internal Audit 2024
On May 2, 2006, the State Water Resources Control Board (SWRCB) adopted Sanitary Sewer Order No. 2006-0003. This order contains requirements for the monitoring, reporting, and development of implementing a Sanitary Sewer Management Plan (SSMP). The SSMP documents the city’s program to properly operate and maintain its sanitary sewer system.
The elements of an SSMP include:
1. Goals
2. Organization
3. Legal Authority
4. Operations and Maintenance Program
5. Design and Performance Provisions
6. Overflow Emergency Response Program
7. Fats, Oils and Grease (FOG) Control Program
8. System Evaluation and Capacity Assurance Plan
9. Monitoring, Measurement and Program Modifications
10. SSMP Program Audits
11. Communication Program
In accordance with the requirements of the SSMP, the following audit measures the city’s progress in the implementation of the SSMP. Providing quality, safe, and reliable sewer service at a reasonable cost is essential to fulfilling the City's Public Works’ Mission Statement: To "provide the highest level of service to the residents of Patterson while maintaining the community’s infrastructure in the most cost-effective manner possible. We constantly strive to improve our customer service and efficiency." The city has developed the following goals to meet the requirements of the Sanitary Sewer Order and uphold our mission statement:
Section 1 – Goals
The key points of this element:
a. Minimize sanitary sewer overflows.
b. Prevent public health hazards.
c. Minimize inconveniences by responsibly handing interruptions in service.
d. Protect the large investment in collection systems by maintaining adequate capacities and extending useful life.
e. Prevent unnecessary damage to public and private property. f. Use funds available for sewer operations in the most efficient manner. g. Convey wastewater to treatment facilities with a minimum of infiltration, inflow and ex-filtration.
h. Provide adequate capacity to convey peak flows.
i. Perform all operations in a safe manner to avoid personal injury and property damage.
j. Minimize impacts on environmentally sensitive waterways such as the San Joaquin River.
The City’s performance relating to this section’s key point:
The city has continued to consistently meet these goals. The current maintenance plan encompasses the entire system but also places focus on known Hot Spots within the system.
These are sections of the system that are prone to Fats, Oils, and Grease (FOG). Preventive maintenance minimizes sanitary sewer overflows (SSO) thereby protecting human health and the environment. Key aspects that have contributed to the City’s current success with stated goals are the maintenance and FOG programs. The City has worked to improve these activities, which has resulted in no SSOs in six years. The chart in Figure 1 depicts the dramatic decrease in SSOs. The last spill occurred in 2018 then dropped to zero in 2019 and remain nonexistent to date. (See next page) SSO CHART
Figure 1
SSO CHART
Recommendation – Future actions relating to this section’s key points:
Continue maintenance efforts. Preventative maintenance is the key to achieving the established goals. The FOG program has also been successful in the prevention of SSOs and City staff must continue efforts to promote the program.
Section 2 – Organization
The City is required to identify the name of the authorized representative as described in the Sanitary Sewer Order. In addition, the SSMP must list and provide an organization chart for the persons responsible for implementing the SSMP program.
The City’s performance relating to this section’s key point:
Staff have been identified and trained in the various elements of the SSMP. The number of operators attached to the Collections Division is four in addition to the division’s supervisor.
The five operators have been trained in the aspects of sewer collection system maintenance and SSOs. The operators are sent for additional training as it becomes available through organizations such as the California Water Environment Association (CWEA). All operators and the division’s supervisor are certified Collection Systems Operators. In addition, there are other maintenance workers and division supervisors who are trained and certified in collections
system maintenance and SSO response procedures. This structure has worked well, and all reports are completed in a timely manner. The current workflow for SSOs is depicted in Figure 2 (next page).
Figure 2.
Recommendation – Future actions relating to this section’s key points:
The organizational flow related to SSOs has worked well and does not need to change at this time. However, the Streets/Collections division has added new employees who do not have very much experience with SSOs. It is advisable to train them thoroughly in response and reporting procedures. The administrative arm of the operation has several staff members trained in SSO reporting procedures and who are familiar with the California Integrated Water Quality System (CIWQS) web portal – no changes recommended.
Section 3 – Legal Authority
The City must demonstrate that it possesses legal authority to:
• Prevent illicit discharges in its sanitary sewer system. • Require proper design and construction of the infrastructure. • Ensure access for maintenance, inspection, and repairs.
During Business
Hours
• Limit the discharge of FOG and other debris.
• Enforce violations of its sewer ordinances.
The City’s performance relating to this section’s key point:
The legal authority required for the SSMP by the SWRCB is provided in the City's municipal code. Title 13 of the municipal code contains three chapters dedicated to the sewer system.
The following is a description of these chapters:
Prevention of Illicit Discharges
13.02.490
Prohibits leaders from roofs, surface drains for rainwater or storm sewers, from being connected to any sanitary sewer and prohibits any surface, storm water, or artesian well flows from entering the sewer system.
13.02.500

Allows the City to require the installation and maintenance of grease interceptors.
13.02.090
Prohibits the depositing of any objectionable waste in an unsanitary manner on public or private property within the City.
Enforcement
13.02.880 – 13.02.930
Provides the City authority to issue notices of violations, designate nuisances, provides disconnection authority, establish reconnection criteria, and abate nuisances.
Recommendation – Future actions relating to this section’s key points:
The section pertaining to sewer use is outdated and staff is revising this section of the municipal code. The revisions to the code will allow for greater flexibility to address pre-treatment prior to discharge into the collection system. Sampling results indicate there is at least one establishment that will require additional pre-treatment due to high levels of Biochemical Oxygen Demand (BOD), Salinity and Total Dissolved Solids (TDS). These levels have been consistently high and require additional attention.
Section 4 – Operations and Maintenance Program
An operations and maintenance program are vital as it provides processes and procedures for the functionality of the system. Preventative maintenance plays a vital role in preserving the system and keeping the city in regulatory compliance. Key elements of the section:
• Collection System Map: Collection system agencies are required to maintain up to date maps of the sanitary sewer system, showing all gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable storm water conveyance facilities.
• Preventive Operation and Maintenance Activities: Describe routine preventive 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 Preventive Maintenance (PM) program should have a system to document scheduled and conducted activities, such as work orders.
• Rehabilitation and Replacement Plan: A replacement and rehabilitation plan must be developed 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 (CIP) that addresses proper management and protection of 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 CIP.
• Training: Training must be provided on a regular basis for staff in sanitary sewer system operations and maintenance, and contractors must be required to be appropriately trained.
• Equipment and Replacement Part Inventories: Equipment and replacement part inventories must be provided, and critical replacement parts must be identified.
The City’s performance relating to this section’s key point(s):
The city has a collections system map that displays the location and sizes of sewer lines and the placement of manholes. The maps are readily available in Public Works’ offices as well as collections division utility trucks. City staff note irregularities on the maps and submit corrections to the City engineer. The affected map grids are corrected, and new pages are printed and distributed accordingly. These updates occur every six months (as needed).
The Collections Division is in the process of cleaning the entire sewer collections system approx. 63 miles. Public Works currently has four full-time employees in the Collections Division. In addition to a vacuum/mainline cleaning truck the City has a mainline camera unit to inspect and record the condition of the City’s collection system. The mainline camera developed quality issues and has been replaced. Since the last audit the Collections crew has cleaned and inspected 18.82 miles of sanitary sewer mains and 11.3 miles of storm sewer mains. The crew
has also repaired or replaced 19 sanitary sewer laterals. The City has purchased a new vacuum truck to replace the current (aging) vehicle. The older unit will remain in the fleet as a backup to the new truck providing continuous coverage during maintenance/repairs of the new unit. The Water Division also has a vacuum truck that may be used in the event both Collections vehicles are unable to function. The equipment is used to inspect the hot spots in the collection system to determine if the sewer mainline is sound in these areas. The results of the mainline inspections has been positive, and the creation of these hot spots is attributed to FOG. Public outreach is a component of the City’s FOG program and will be addressed in future activities related to the program. The City has identified critical components of the sewer system and currently maintains an inventory of critical spare parts, including spare parts for vehicles and equipment, which are centrally stored at the Corporation Yard. A 15-year equipment maintenance replacement schedule is in place for sewer and storm drainage systems equipment.
The City’s system is divided into sectors based on the sewer utility map, and the Collection’s crew will complete a sector before moving on to the next section. The City uses the Mobile MMS asset management software to record the size and condition of pipe, the footage of pipe cleaned, and the type of debris (if any) encountered. The software is installed on an Apple IPAD tablet and includes a map of the collections system. This digital map will display the areas that have been serviced once the data is entered. Areas known to have issues with sewer line blockages due to FOG are considered “hotspots” and are hydro flushed monthly to minimize the chance that a line obstruction will go undetected. There are nine hot spots identified that are hydro flushed monthly. Lift stations are also inspected weekly and chemical treatment such as degreaser or odor control is applied as needed. Residents experiencing issues with their sewer lines may call the Public Works Department and City staff is dispatched immediately to address the issue. The incident is then documented in the Departments work order program (Mobile MMS). Calls from residents placed after hours are routed to the City’s answering service and addressed by the City’s on-call personnel.
Operations and maintenance functions are performed by City staff, and training is tantamount to a successful program. Equipment training is obtained from manufacturer representatives and/or vendors of the products/equipment used in the maintenance program. Professional organizations such as the CWEA offer training and certification in storm water and wastewater collection. The City has staff members certified in these fields who attend seminars and workshops to meet training requirements and obtain continuing education units (CEUs) for recertification purposes.
Recommendation – Future actions relating to this section’s key points:
The City continues to do well in this section as evidenced by the lack of an SSO in five years.
The maintenance program continues to improve, and the collections system is being monitored and maintained better than ever. However, the 15-year equipment maintenance replacement schedule was implemented in 2008 and will need to be updated by the end of 2027.
The number of sewer overflow equipment stations has dropped from four to zero.
The CIP should be updated and implemented as funding becomes available. Plans are in place for expansion of the WQCF (Phase 3 project) and the city continues identifying funding sources to pay for the project. Finally, a new administration building was completed in 2023.
Section 5 – Design and Performance Provisions
This section requires that the City identify design and construction standards for sanitary sewer systems and procedures and standards for the inspection and testing of new sewers and other appurtenances.
The City’s performance relating to this section’s key point(s):
The City maintains standard specifications for the construction of public improvements. Details or specifications are updated periodically when change is needed. The last update occurred in March 2011. The City standards also provide specifications for the inspection and testing of new public sewer facilities. Details and specifications are also changed to reflect accepted design practices and industry standards.
Recommendation – Future actions relating to this section’s key points:
City staff currently review the standards and make recommendations for updates annually.
Recommendations are forwarded to the City Engineer who reviews the proposed updates and makes additional recommendations (if necessary) before inclusion into the standards. This practice has worked well and should continue.
Section 6 – Overflow Emergency Response Plan
The city must develop and implement an overflow emergency response plan that identifies measures to protect public health and the environment.
Key points:
• Proper procedures for informing primary responders and regulatory agencies of all SSOs.
• An overflow response program.
• Procedures to ensure the Emergency Response Plan is followed.
• A program to contain or prevent SSOs as well as minimize or correct any adverse impacts on the environment resulting from the SSO.
The City’s performance relating to this section’s key point(s):
The City’s emergency response plan was prepared by Risk Management Solutions. The plan is reviewed yearly, and pertinent contact information is updated. The plan is also revised to reflect the SWRCB rules and guidelines. The Deputy Director, each Public Works Supervisor, and on-call staff members have a copy of the plan and field forms in each respective field vehicle.
The packets contain easy to follow flow charts to assist staff members in determining the severity of the spill as well as strategies for dealing with the spill. As required the City submits a monthly electronic report of all spills or non-spills to the SWRCB.
Calls received during business hours will be responded to immediately to minimize the impact of an SSO. Calls received after business hours will be responded to within one hour by the Public Works on-call person. The on-call person will assess the situation and summon assistance if needed. Staff has been trained in SSO response procedures and continue to learn new techniques from professional organizations mentioned in Section Four of this report.
The City also encourages residents (via website and newsletter) to call Public Works if they are experiencing sewer issues inside the home. The Department’s response to such calls is to dispatch a staff member to check the sewer lines that service the neighborhood in question.
This will reveal if the source of the issue inside the home is due to an obstruction in the City sewer main line or specific to the residence. This practice will help avoid a potential SSO. Staff are instructed to give all calls related to sewer issues/SSOs top priority. Supervisors, Streets/Collection crew members and on-call staff have participated in the training exercises.
Recommendation – Future actions relating to this section’s key points:
Blackwater Consultant Engineers have been retained and updated the current SSMP. This includes updating the Overflow Emergency Response Plan which is now termed the Spill Emergency Response Plan (SERP). The updated plan must reflect changes instituted by the SWRCB.
Section 7 – Fats, Oils, and Grease (FOG) Control Program The City is required to evaluate its service area to determine if a FOG control program is warranted. The City has had four SSOs during the years 2016 and 2018, and the cause was found to be caused by FOG. Staff has prepared and implemented a FOG source control program to reduce the amount of these substances discharged into the sewer system.
Key points of the plan:
• A public education outreach program.
• The legal authority prohibits discharges to the system and identify measures to prevent SSOs caused by FOG.
• Requirements to install grease removal devices such as traps or interceptors. • Authority to inspect grease producing facilities and enforcement authority. • Identify sewer system sections subject to FOG blockages and establish a cleaning maintenance schedule for each section.
• Develop and implement source control measures for all sources of FOG discharged to the sanitary sewer system.
The City’s performance relating to this section’s key point(s):
The city currently addresses the public outreach section of the plan by posting information on the City web site as well as articles in the citizen newsletter. The articles identify FOG and the proper way for citizens to dispose of such debris. Since 2013 the Public Works Department has embarked on a continuous public outreach campaign featuring many of the programs promoted by the department. FOG is one of the key programs in the presentations and City staff has taken every opportunity available to reach as many people as possible. Staff visits elementary and middle schools via scheduled visits and special occasions such as Public Works Week and Arbor Day celebrations. Public Works operations crews have participated in Career Day events at Patterson High School, Public Works open-house and Walnut Grove Elementary. .
Public Works continues its public outreach by setting up a booth to promote these programs during the annual Apricot Fiesta and other outdoor events. The Department has been very successful in distributing educational materials at these events and it will continue to participate in the years to come.
The Department has created and instituted an official FOG program that covers all FOG producing businesses as well as public outreach. Staff members assigned to the program include a Public Works Deputy Director, Public Works Inspector, and Environmental Compliance Specialist. The number of Public Works Inspectors has increased to three and are now better suited to assist in the program. Staff designed and produced a FOG binder with important outreach material that outlines the program as well an educational component that describes the hazards of FOG and the equipment necessary to contain the pollutants. Included in the kit are maintenance logs and the procedure for reporting maintenance activities to the City. Also included is the legal authority for requiring the maintenance as well as the authority for inspecting grease interceptor facilities. Staff have identified all FOG producing establishments
and has conducted meetings with facilities that currently have grease interceptors. City staff continue to conduct the introductory meetings with new businesses as they open in the City.
Maintenance activities for these establishments are monitored to ensure that the frequency of the activity is adequate, and that Best Management Practices (BMPs) are being followed.
There are currently older FOG producing establishments that do not have grease interceptors.
This is due primarily to a lack of space as these locations are in the downtown district. The Collections Division periodically inspects the sewer mains servicing these facilities to determine the volume and impact of the FOG generated by these businesses. Staff recognizes that in some cases a grease interceptor may not be practical due to the limited space available in some of the older locations and that the cost of an interceptor may cause a financial hardship on some if not all the older businesses that generate FOG. Staff will consider alternatives (such as a grease trap in lieu of an interceptor) on a case-by-case basis.
The following is the legal authority currently in the City’s municipal code:
Section 13.02.510
City’s municipal code provides the City the authority to prohibit grease disposal into the City’s sewer system. The section also identifies the types of wastes that are prohibited.
Sections 13.02.540 and 13.02.550
City’s municipal code require grease interceptors be provided and maintained.
Section 13.02.960
City’s municipal code provides the authority for an authorized City representative to enter facilities and properties for the purposes of inspection, measurement, sampling or testing as necessary for the enforcement of the provisions of the ordinances and rules of the City.
Sections 13.02.880 through 13.02.930
City’s municipal code provides authority to issue notices of violations; designates nuisances; provides disconnection authority; establishes reconnection criteria; nuisance abatement.
Areas subject to blockages (Hot Spots) are identified. These areas are routinely inspected and cleaned. This is an effective method for preventing SSOs resulting from FOG.
Recommendation – Future actions relating to this section’s key points:
The current FOG program model requires staff time to ensure that establishments comply with the program. This includes tracking the maintenance schedule for all facilities and ensuring that
reports are submitted by each business. Staff must also review the data and perform site inspections to also ensure that the reported maintenance is being performed and that each grease interceptor is well maintained. While the workload may be difficult at times due to the limited number of employees available, they must stay abreast of the facility maintenance schedules for the program to be effective. Increasing the number of inspectors has proven to be beneficial. Public outreach should be maintained at appropriate levels to promote voluntary compliance with residents.
Section 8 – System Evaluation and Capacity Assurance Plan The City must prepare and implement a capital improvement program (CIP) plan that will provide hydraulic capacity of key sanitary sewer system elements for dry weather peak flow conditions as well as appropriate design for storm or wet weather event.
Key Elements:
• Evaluation: Evaluate those portions of the sewer system that are experiencing or contributing to an SSO discharge caused by hydraulic deficiency. • Design Criteria: Where such criteria do not exist or is deficient, the evaluation listed above will aid in establishing appropriate design criteria. • Capacity Enhancement Measures: Establish a short- and long-term CIP to address identified hydraulic deficiencies.
• Schedule: The City must develop a schedule of completion dates for all portions of the CIP.
The City’s performance relating to this section’s key point(s):
The City has not experienced any SSOs due to hydraulic deficiency. All SSOs thus far are a direct result of FOG deposited in the system. The City’s standard specifications provide design criteria for new construction of sewer facilities including design flow rates, pipe material/size and other factors. The same standards are utilized when the replacement of existing sewer facilities is necessary.
Recommendation – Future actions relating to this section’s key points:
The condition of the lift station on Ward Ave. has been evaluated, and a retrofit/upgrade is in the design process as of this writing. Potential construction timeline has not yet been determined.
Section 9 – Monitoring, Measurement, and Program Modifications
The City shall:
• Maintain information that can be used to establish and prioritize SSMP activities. • Monitor the implementation and measure the effectiveness of each element of the SSMP.
• Assess the success of the preventive maintenance program. • Update program elements.
• Identify and illustrate SSO trends.
The City’s performance relating to this section’s key point(s):
The city currently monitors the following items:
• The number, cause, and locations of blockages.
• The number, cause, location and volume of SSOs.
• The number and reason for customer complaints.
• Response time.
• Date, length of pipe cleared, and debris found.
The following items are also monitored and/or measured to determine the effectiveness of the SSMP, assess the effectiveness of the maintenance program and update program elements as appropriate.
• Number and location of blockages due to FOG.
• Number and location of SSOs due to FOG.
• Number and location of FOG producing facilities.
• Total number and volume of SSOs.
• Number of repeats SSOs.
• Number of mainline blockages.
Recommendation – Future actions relating to this section’s key points:
The current maintenance activities performed on the collections system and the FOG program have helped to improve stability. System monitoring, data collection, and event response
procedures are currently in place. As previously stated there has not been an SSO since 2018.
This was due to FOG in a residential area and no doubt caused by household practices. It was previously recommended that Staff should select the neighborhoods surrounding an SSO or mainline blockage and distribute outreach materials after each occurrence. Part-time staff could be utilized to canvass the area and deliver materials door to door. There has not been an opportunity to use this method due to the lack of SSOs.
Section 10 – Program Audits
The City must conduct periodic internal audits appropriate to the size of the system and the number of SSOs. At a minimum these audits must occur every two years. The audit shall focus on evaluating the effectiveness of the SSMP and the City’s compliance with the SSMP requirements identified in the plan.
The City’s performance relating to this section’s key point(s):
This is the fifth audit of the City’s SSMP which was updated in 2016. The report lists the progress and development of SSMP elements. A description of improvements to the sewer system and planned improvements is included. A copy of the completed audit will be kept on file with the SSMP as required by the SWRCB.
Recommendation – Future actions relating to this section’s key points:
The City should continue the process of auditing the SSMP every two years but will follow the upcoming changes the SWRCB is implementing which requires an audit every three years.
Section 11 – Communication Program
The city must communicate on a regular basis with the public on the development, implementation, and performance of the SSMP. The communication system shall provide the public the opportunity to provide input to the City as the program is developed and implemented. The City must also create a plan of communication with systems that are tributary and/or satellite to the City’s sanitary sewer system.
The City’s performance relating to this section’s key point(s):
The City maintains a web site to inform the public of City activities. General and other important information is available to the public. Tips on acceptable use of garbage disposals and contact information for reporting sewer issues is provided. Other communication tools include utility bill inserts, and articles in the City’s Citizen Newsletter. As previously stated, the
Public Works Department has made public outreach a priority and takes every opportunity to present educational materials year-round.
The Diablo Grande subdivision is the only satellite system discharging to the City’s sewer system. They are also responsible for preparing an SSMP for their system. Diablo Grande sends via email advance notice to the City of Patterson Chief Wastewater Plant Operator of flushing activities. The agreement with Diablo Grande should include the sending of, via email, a monthly report of flows into Patterson. The agreement should include a provision for City Staff and Diablo Grande personnel to meet as needed.
Recommendation – Future actions relating to this section’s key points:
While the City does provide some general tips on acceptable waste, it does not provide information on the City’s SSMP. This forum could be used to provide the public with information on the development and implementation of the SSMP. The use of utility billing inserts should be continued as it is an effective way of reaching customers without additional postage or envelopes.
Appendix C – SSMP Staff Names and Phones Numbers must be updated as personnel has changed, and additional positions have been added to the list.
Section 12 – SSMP Completion and Certification
The city must certify that the SSMP follows all Waste Discharge Requirements (WDR) and complete the certification form provided in the Online SSO Database. The form must be printed and signed and sent to the State Water Board.
The City Council adopted the current SSMP as fully implemented and in compliance with the terms of the general waste discharge requirements on October 3, 2023, by Resolution 2023-45.
The SSMP was certified, and the appropriate form submitted to the State Water Board.
