Deficient Reporting |
The California Regional Water Quality Board, San Diego Region (San Diego Water Board) completed a limited review of the County of San Diego’s (Enrollee’s) submitted Sewer System Management Plan (SSMP) against the requirements of sections 8.1 and 8.2 of Attachment D to State Water Resources Control Board Order WQ 2022-0103-DWQ, Statewide Waste Discharge Requirements, General Order for Sanitary Sewer Systems (General Order) and determined that the SSMP is incomplete. While the SSMP was timely uploaded to the California Integrated Water Quality System (CIWQS) database by May 2, 2025, it failed to address the following permit requirements:
8.1 System Evaluation and Condition Assessment
The Plan must include procedures to:
• Evaluate the sanitary sewer system assets utilizing the best practices and technologies available;
• Identify and justify the amount (percentage) of its system for its condition to be assessed each year;
• Prioritize the condition assessment of system areas that:
• Hold a high level of environmental consequences if vulnerable to collapse, failure, blockage, capacity issues, or other system deficiencies;
• Are located in or within the vicinity of surface waters, steep terrain, high groundwater elevations, and environmentally sensitive areas;
• Are within the vicinity of a receiving water with a bacterial-related impairment on the most current Clean Water Act section 303(d) List;
o Assess the system conditions using visual observations, video surveillance and/or other comparable system inspection methods;
o Utilize observations/evidence of system conditions that may contribute to exiting of sewage from the system which can reasonably be expected to discharge into a water of the State;
o Maintain documents and recordkeeping of system evaluation and condition assessment inspections and activities; and
o Identify system assets vulnerable to direct and indirect impacts of climate change, including but not limited to: sea level rise; flooding and/or erosion due to increased storm volumes, frequency, and/or intensity; wildfires; and increased power disruptions.
8.2 Capacity Assessment and Design Criteria
The Plan must include procedures to identify system components that are experiencing or contributing to spills caused by hydraulic deficiency and/or limited capacity, including procedures to identify the appropriate hydraulic capacity of key system elements for:
• Dry-weather peak flow conditions that cause or contributes to spill events;
• The appropriate design storm(s) or wet weather events that causes or contributes to spill events;
• The capacity of key system components; and
• Identify the major sources that contribute to the peak flows associated with sewer spills.
The capacity assessment must consider:
• Data from existing system condition assessments, system inspections, system audits, spill history, and other available information;
• Capacity of flood-prone systems subject to increased infiltration and inflow, under normal local and regional storm conditions;
• Capacity of systems subject to increased infiltration and inflow due to larger and/or higher-intensity storm events as a result of climate change;
• Increases of erosive forces in canyons and streams near underground and above-ground system components due to larger and/or higher-intensity storm events;
• Capacity of major system elements to accommodate dry weather peak flow conditions, and updated design storm and wet weather events; and
• Necessary redundancy in pumping and storage capacities.

SSOS |
Type: Category 1 Spill; Rainfall Exceeded Design, I and I (Separate Collection System Only) caused 46850 gallons of sewage to spill from Manhole at 5682 Sweetwater Rd to Surface Water |
Plan Rehabilitation or Replacement of Sewer. Improvements include replacement of approximately 1,600 feet of existing 24-inch to
36-inch VCP and RCP sewer pipe with 30-inch to 42-inch PVC sewer pipe to provide additional hydraulic
capacity. A preliminary design report has been completed and design plans and specifications are
anticipated to be completed by the end of calendar year 2023; construction is anticipated to be completed
by Summer 2024. Funding for construction of the improvements, estimated at $3M, is included in the
District’s current and future year operating budget. |

SSOS |
Type: Category 2 Spill; Flow Exceeded Capacity (Separate Collection System Only), Rainfall Exceeded Design, I and I (Separate Collection System Only) caused 11025 gallons of sewage to spill from Manhole at 10557 Jamacha Blvd to Drainage Conveyance System, Groundwater Infiltration Basin or Facility, Surface Water |
Other (specify below). Spill was due to heavy rain event which led to excessive I&I, overwhelming system capacities. |

*As of 5/20/2010, the Water Board's Enforcement Policy requires that all violations be classified as 1, 2 or 3, with class 1 being the highest. Prior to this, violations were simply classified as Yes or No. If a 123 classification has been assigned to a violation that occurred before this date, that classification data will be displayed instead of the Yes/No data.
