Tesoro Master Mutual Water Company (TVMMWC) / California Water Service (Cal Water) Sanitary Sewer Management Plan (SSMP)

The California State Water Resources Control Board (SWRCB) adopted Statewide General Waste Discharge Requirements (WDR) Order No. 2006-003, for wastewater collection systems. The WDR requires all enrollees to develop a SSMP and make it available to the public, to the SWRCB, and the Regional Water Control Board (RWQCB).

The purpose of the SSMP is to minimize the frequency and severity of Sanitary Sewer Overflows.

The SSMP must be audited at least every two (2) years and updated every five (5) years from the original adoption date by the Enrollee’s governing board. All federal and state agencies, municipalities, counties, districts, and other public entities that own or operate sanitary sewer systems with piping greater than one mile in length are required to comply with the WDRs.

The Order includes eleven (11) mandatory elements that must be addressed in the SSMP. The SSMP elements describe the activities the TVMMWC / Cal Water will employ to manage, operate, and maintain the wastewater collection system effectively.

The below documents constitute the entirety of the TVMMWC / Cal Water SSMP.
