The project proposes approval of a State Revolving Funds (SRF) loan application to compile an inventory and investigation of lead service lines for privately-owned water services. Publicly owned lead services were installed in the City of San Diego (City) through the mid-1900s when cast iron and copper service lines became standard; however, the City has not inventoried nor replaced lead services on the privately-owned customer side of the water meter as it was not a regulatory requirement at the time. In accordance with the EPA’s recent Lead and Copper Rule Revisions (LCRR), the project will develop a Lead Service Line Inventory (LSLI). The City has engaged an engineering consultant to develop a Customer Service Line Inventory Plan that leverages existing data from City records with additional data sources related to lead service lines. This Inventory Plan is currently in place and the consultant has begun the investigation and inventory phase of the project. Concurrently, the project proposes development of a plan to replace any lead service lines discovered by July 22, 2031, which is 10 years after the effective date of the LCRR Act. Physical replacement of the lead service lines is not part of the project and will be subject to future environmental review.
