Water Conservation and SCWA

Protecting our water starts with you

Suffolk County’s only source of drinking water is our underground aquifer system—a natural resource formed thousands of years ago. While it provides an abundant supply, it is not unlimited. Demand is rising, making conservation essential for long-term sustainability.

Conservation is not only about how much water we use—it is also about when we use it. During spring and summer, demand spikes in the early morning when most sprinkler systems run. That strain can drive the need for additional wells, pipes and pump stations—projects that can affect water rates.
