About Sewer Management
The City of Lomita is committed to maintaining a reliable, efficient and environmentally responsible sewer system that protects public health, property and local waterways. The system collects and transports wastewater from homes and businesses to regional treatment facilities, where it is treated and safely discharged or reused.
The City’s sanitary sewer collection system serves a population of approximately 20,000 residents and consists of roughly 36 miles of gravity sewer pipelines. The City’s legal authority to own and operate the sanitary sewer system is derived from its incorporation as a City. The City, on June 30, 1964, granted the County of Los Angeles the consent and jurisdiction to annex portions of the sewer system into the Consolidated Sewer Maintenance District (CSMD or County). By that action, the City has entrusted the management, operation and maintenance of its local sanitary sewer system to the CSMD. The City, however, maintains ownership of the sewer system and is responsible for ensuring that the public sewer infrastructure is correctly designed, adequately sized and easily maintained.
To ensure proper operation and maintenance, the City follows a Sewer System Management Plan (SSMP). This plan outlines goals, procedures and responsibilities for preventing sanitary sewer overflows (SSOs), improving system performance and complying with regulations from the State Water Resources Control Board (SWRCB).
