About

The Locust Valley Water District is dedicated to protecting our most precious natural resource – water.
Through a variety of conservation efforts and educational initiatives, we are helping residents save water, which protects our aquifer so that ample, clean, and affordable water will be available for the community’s future generations.

Long Island has a phenomenal natural drinking water resource situated deep below the surface of the earth. Called aquifers, these underground layers of highly porous sand, gravel, sediment, or rock contain between 65 and 120 trillion gallons of our most precious resource.
