EPA releases 7th Drinking Water Infrastructure Needs Survey and Assessment

The 7th DWINSA estimates that $625 billion will be needed for infrastructure improvements over the next 20 years. This is a 32% increase over the 6th DWINSA ($472.6 billion). By law, each state is guaranteed a minimum allotment of 1% of the total amount of available funding. Starting in FY23, this allotment formula will be used to distribute the DWSRF Base Appropriations, the Bipartisan Infrastructure Law (BIL) General Supplemental, and the BIL Emerging Contaminants funds. EPA used information collected in the 7th DWINSA on service line materials to develop a separate allocation formula to distribute the DWSRF BIL Lead Service Line Replacement fund. EPA developed the allotment formula based on the number of projected LSLs in each state.
