Charleston Water System is proud to be a WaterSense partner. 

WaterSense is a partnership program sponsored by the US Environmental Protection Agency (EPA) to protect the future of our nation's water supply by promoting and enhancing the market for water-efficient products and services.

It's like EnergyStar for water fixtures. 

Look for WaterSense Labeled Products
Fixtures 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.
