Greer CPW has been providing drinking water to the citizens of Greer since 1913. In 1928, a water filter plant was built on Duke Street and soon thereafter a raw-water pump station was constructed on the South Tyger River. In 1957, the Lake Cunningham Reservoir was constructed at Highway 14 and River Rd. In 1971, an 8 million gallon-per-day Water Filter Plant was constructed on River Rd., adjacent to the lake. A backup reservoir, Lake Robinson, was completed in 1984, and in 1992, the Water Filter Plant capacity was expanded to treat up to 16 million gallons per day. To meet the increased demand for water, Greer CPW upgraded the plant to 24 MGD capacity in 2004.
Water arrives at homes and businesses through the distribution system, which is a network of pipes, valves, fire hydrants, and storage tanks. Greer CPW has approximately 400 miles of water mains. Greer CPW has six storage tanks throughout the distribution system to maintain pressure and meet peak water demands. Lake Cunningham and Lake Robinson are the sources of water for Greer CPW customers.
