Quality Water: Source to Tap

The team at Greenville Water works diligently to protect our watersheds, ensure our treatment practices are highly effective, and provide our customers with safe drinking water. Greenville Water meets all of the strict drinking water standards established by the Environmental Protection Agency (EPA) and the South Carolina Department of Health and Environmental Control (SCDHEC). In order to protect its customers, Greenville Water and SCDHEC collects over 36,000 samples and performs more than 100,000 water quality tests annually. Water samples are collected and tested during the treatment process and as the water is delivered to customers through approximately 3000 miles of pipeline.

Where does my drinking water come from?

Greenville Water draws water from three sources: Table Rock Reservoir, North Saluda Reservoir, and Lake Keowee. Table Rock and North Saluda Reservoirs are both located in the foothills of the Blue Ridge Mountains in northern Greenville County. Greenville Water owns 100 percent of both watersheds. Greenville Water regularly patrols and carefully maintains these uninhabited, pristine lands. The properties are further protected by a Conservation Easement with The Nature Conservancy. Lake Keowee is owned by Duke Energy.

How is my water treated?

All water supplied to you is thoroughly treated and disinfected. The Adkins Filter Plant, a conventional filtration, draws water from Lake Keowee. The Stovall Filter Plant was placed in service in July 2000, to provide filtration for all water drawn from the Table Rock and North Saluda Reservoirs. This plant is one of the largest in the United States to use Dissolved Air Flotation (DAF) in the treatment process. All treatment plants are maintained and monitored by State Certified Environmental Systems Operators who are thoroughly trained to make routine chemical and physical tests for treatment control.
