The 100 Largest Public Water Supplies in South Carolina

Roy Newcome, Jr.


Public water supplies in South Carolina use nearly 400 million gallons per day, 80 percent of it obtained from surface-water sources and 20 percent from wells. The five largest public supplies are Charleston, Greenville, Columbia, Spartanburg, and the Beaufort-Jasper County Water Authority. Sumter, the largest supply using only ground water, and Anderson are tied for sixth place. The range in pumping for the 100 largest public supplies is 50 million gallons per day for the largest to about two-thirds of a million gallons per day for the smallest.
