A long history of boosting local water supplies and water quality
Our region is home to some of the best quality water in California.
Much of that has to do with work the District has been doing for nearly 100 years: capturing and recharging water from area rivers and streams into the Bunker Hill Groundwater Basin, which today serves some 70% of the local population.
This surface water, fed by pristine snowmelt from the nearby San Bernardino Mountains, is captured in percolation ponds where it seeps slowly through layers of sand and silt that filter out contaminants — just as nature intended.
This high-quality water blends with and improves the purity of existing groundwater, and enhances water resilience for our drought-prone community.
