Charleston Water System is committed to protecting the future of our national and local water supply through water-efficient practices, products, and services.

That's why we've partnered with the U.S. Environmental Protection Agency (EPA) to bring to you WaterSense, a national program that offers you a simple way to make product choices that use less water—and perform as well or better than your existing products.

About WaterSense

WaterSense is a voluntary public-private partnership program sponsored by the US EPA. Its mission is to protect the future of our nation's water supply by promoting and enhancing the market for water-efficient products and services.

WaterSense Labeled Products

Products that bear the WaterSense label meet EPA criteria for water efficiency and performance. WaterSense labeled products use about 20% less water than similar products and perform as well or better than their less efficient counterparts.

Currently, the WaterSense program includes bathroom faucets, high efficiency toilets, and landscape irrigation services. More types of products will be added in the future.
