The Long-Term Groundwater Replenishment Program (GRP) is a voluntary, 20-year program open to water users solely reliant on groundwater in the Modesto Subbasin. In wet years where MID irrigators and the City of Modesto have received uncapped allocations, MID will make surface water available to applicants.
The GRP is part of a series of groundwater management actions spurred by the Sustainable Groundwater Management Act. These actions are aimed at reducing reliance on pumping, promoting groundwater storage programs, improving both the availability and quality of water to disadvantaged communities, providing flood control, and protecting our groundwater for generations.
MID is now accepting applications for the Long-Term Groundwater Replenishment Program.
If you have questions about the GRP application process or your eligibility, please contact MID Water Operations at (209) 526-7562.
