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

HR 337 redirects $3 million annually from unobligated funds to support groundwater recharge, aquifer storage, and water source substitution projects. It authorizes $3 million per year for fiscal years 2026-2031 to be transferred to the Secretary for these specific water management initiatives. The bill directly affects state and local water agencies implementing these projects by providing dedicated funding. It does not create new programs but reallocates existing unobligated funds from the Infrastructure Investment and Jobs Act. The key mechanism is the annual transfer of $3 million for these water storage and supply projects.
