See How We’ve HelpedBipartisan Infrastructure Law
The Bipartisan Infrastructure Law (BIL), also known as the Infrastructure Investment and Jobs Act (IIJA) of 2021, provides $15 billion nationwide funding through the DWSRF for lead service line (LSL) identification and replacement for over the next five (5) years. California received $250 million in FY 2022, and future allotments are expected in future years. Funding is available to community water systems and nonprofit noncommunity systems to complete LSL inventory and replacement. The IUP and the LSL Replacement Funding Supplemental IUP provide guidelines and funding criteria and will be updated annually.

DWSRF can finance publicly owned community water systems (e.g., counties, cities, districts), privately-owned community water systems (e.g., for-profit water utilities, non-profit mutual water companies), non-profit or publicly-owned non-community water systems (e.g., public school districts), and community water systems created by the project. Eligible project types include treatment systems, distribution systems, interconnections, consolidations, pipeline extensions, water sources, water meters, and water storage.
