The Sacramento Regional Water Bank is a system of groundwater wells, pumps and pipelines that allow local water providers to pump out and refill underground water reserves to serve local water customers.

The aquifers underlying the Sacramento region have enough capacity to store twice the volume of water as Folsom Reservoir.

Local water providers are working to expand water banking in the Sacramento region as we face the ever-familiar impacts of climate change, which creates a Catch 22 for our water system—the need to release water from Folsom Reservoir to protect our community from flood rather than storing water for drier days.
