To provide technical and financial assistance for groundwater recharge, aquifer storage, and water source substitution projects.

This bill lets the government use unused funds from the Infrastructure Investment and Jobs Act to help communities protect and refill their underground water supplies. From 2026 through 2031, up to $3 million each year can be shifted to provide technical help and money for projects like groundwater recharge (putting water back into the ground), aquifer storage and recovery, and switching to other water sources to protect aquifers. These efforts focus on areas served by the Bureau of Reclamation, which covers much of the western United States .
