See How We’ve Helped

  Bipartisan 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.
