Greenville Water

exercises more control over its source water than any water system in the world.


Greenville Water draws water from three sources: Table Rock Reservoir, North Saluda Reservoir and Lake Keowee. These watersheds supply a majority of water service to nearly 500,000 residents in the Upstate region of South Carolina, making GW the largest water supplier in the state according to SC Department of Natural Resources.

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 and regularly patrols and maintains these uninhabited, pristine lands. Lake Keowee is owned by Duke Energy.

Water Quality

Greenville Water is nationally known for providing some of the purest drinking water in the country. There are no residents, no commercial, agricultural or industrial facilities located within the watersheds. Because they are protected and remain in a natural, pristine condition, the water quality in these reservoirs is very high. In a national blind taste test of 2011, sponsored by the American Water Works Association, Greenville Water earned the title of "Best Tasting Water in America.
