Sewer System Management Plan (SSMP)

The California State Water Resources Control Board (SWRCB) adopted Statewide Order No. 2006-0003-DWQ Statewide General Waste Discharge Requirements (GWDR) for Sanitary Sewer Systems. The City of Yuba City is required to comply with the GWDR for Sanitary Sewer System.  The purpose of the Order is to require agencies to prepare a plan and schedule for measures to be implemented to reduce Sanitary Sewer Overflows (SSOs) as well as measures to effectively cleanup and report SSOs.

For more information about the GWDR, visit: State Water Resources Control Board.

The City of Yuba City developed Sewer System Management Plans for: (i) Yuba City’s sanitary sewer collection system and (ii) Stonegate Village Subdivision’s sanitary sewer collection system.  These Sanitary Sewer Management Plans are available for review at the Public Works Department office located at 1201 Civic Center Blvd., Yuba City, CA 95993 during City’s regular business hours.  Please contact Mandeep Chohan at (530) 822-7448 if you would like to schedule a visit to review the SSMP and the supporting documents, and/or provide comments.  The comments can also be submitted through email to Mandeep Chohan at mchohan@yubacity.net .  The City of Yuba City staff will review all comments before periodically updating the SSMP document.

There are 11 different elements to the SSMP which are listed and briefly summarized below.

1. Goals
2. Organization
3. Legal Authority
4. Operations and Maintenance Program
5. Design and Performance Provisions
6. Overflow Emergency Response Plan
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

Element 1 describes the City of Yuba City’s Goals for the SSMP.

Element 2 describes the City of Yuba City’s organizational structure related to the sanitary sewer management.

Element 3 describes the City of Yuba City’s legal authority to manage the sewer system.

Element 4 describes the operations and maintenance program of the sanitary sewer collection system.  City’s sewer maintenance field crews maintain the underground sewer collection system.

Element 5 describes the City’s Standards for installation, rehabilitation and repair of sanitary sewer systems.  The City requires that the work related to sanitary sewer system design and construction must follow City’s standard specification, details, and special provisions.  In addition, this element describes the City’s Inspection and testing requirements for the sanitary sewer system new installations, rehabilitation work and repair work.

Element 6 describes the overflow emergency response plan.  This plan describes the field procedures to properly handle a sanitary sewer overflow along with the reporting requirements per the GWDR.

Element 7 describes the Fats, Oil, and Grease (FOG) program.  This program is designed as a preventive program to ensure that FOG related sanitary sewer overflow events are reduced based on permitting and outreach to commercial customers and education of residential customers on proper handling of fats, oils, grease, and food scraps.

Element 8 describes the City’s approach for sanitary sewer system capacity evaluation, design criteria and capacity enhancement measures.  The capacity analysis is conducted through the Hydraulic modeling software using the criteria described in the City’s Wastewater System Master Plan (Master Plan).  The Master Plan is used to schedule and implement the Capital Improvement Program (CIP) projects.  The CIP and the Master Plan is used to determine the needed funding and funding sources.

Element 9 describes the City’s approach to the following: maintain the relevant information to prioritize SSMP activities, monitor and measure effectiveness of each SSMP element, assess the success of Preventative Maintenance Program, update the program elements based on the monitoring/performance evaluations and identify and illustrate sanitary sewer overflow trends.

Element 10 describes the City’s plan for the SSMP program Audits.  The City will conduct the internal audits every two years to determine the effectiveness of the SSMP elements and programs.  A list of priority improvement opportunities will be prepared and updated as part of the audit program.  The program audit will include a final report reviewing the City’s performance and identifying findings.

Element 11 describes the communication program. This element includes the steps to communicate with the public on the development, implementation, and performance of the SSMP.
