Regional Water System

Launched in October 1994, the Santee Cooper Regional Water System was the first regional approach to water distribution in the Lowcountry.

The system has the capacity to draw 36 million gallons of water per day (mgd) from Lake Moultrie. Water is sold wholesale to the Lake Moultrie Water Agency, which is comprised of the Berkeley County Water and Sanitation Authority, the City of Goose Creek, the Moncks Corner Public Works Commission, and the Summerville Commissioners of Public Works. Santee Cooper owns the system's treatment plant as well as the pump stations and facilities near Lake Moultrie's Lions Beach.


The Lake Marion Regional Water System began commercial operation in May 2008 and serves the towns of Santee and Bowman with a system capacity of 8-mgd. Its treatment plant located near Santee is owned and operated by Santee Cooper and the water is sold wholesale to the Lake Marion Regional Water Agency.
