Charleston Water System Municipal Water Report Info

Charleston Water System functions as an independent water and wastewater utility. We deliver clean water services throughout the greater Charleston area. Formally established as the Commissioners of Public Works of the City of Charleston, SC, we operate under an elected Board of Commissioners.

Our team of 430 professionals is committed to protecting public health and the environment by providing reliable, high-quality water and sewer services. The Hanahan Water Treatment Plant produces excellent drinking water distributed through our network of 1,800 miles of water mains. Our facility meets or exceeds all regulatory standards and participates in the Partnership for Safe Water.

We also manage sewer services—not stormwater—via 800 miles of collection mains, over 200 pump stations, and 12 miles of deep tunnels that transport wastewater to our treatment facility. The Plum Island Wastewater Treatment Plant processes approximately 23 million gallons daily, releasing purified water into Charleston harbor.

Our environmental commitment includes an ISO 14001 certified environmental management system (EMS), and we're currently pursuing ISO 14001:2015 certification. Our service area covers Charleston-North Charleston, Hanahan, Ladson, James Island, Daniel Island, Cainhoy, Thomas Island, West Ashley, Hollywood, Ravenel, and Meggett.

We also provide wholesale service to St. Johns Water Company (serving Kiawah and Seabrook Islands), Mt. Pleasant Waterworks, Dorchester County Public Works, Town of Folly Beach, Town of Sullivan's Island, Isle of Palms Water and Sewer Commission, Joint Base Charleston, and Town of Lincolnville.

Charleston Water System Municipal Water Company and CDC
  1. Where does Charleston Water System water come from?
    Charleston Water System supplies surface water to Charleston, South Carolina.
  2. Does Charleston Water System test its tap water?
    Yes. Like every public water system, Charleston Water System must test its water under the federal Safe Drinking Water Act and publish an annual water quality report (Consumer Confidence Report). Ask the utility for the latest report or look for it on its website.
  3. How do I contact Charleston Water System?
    Call 843-308-8200 or visit 103 St. Philip Street, Charleston, SC 29403, or use the contact options on the utility’s website.
  4. Does Charleston Water System water contain lead?
    Water usually leaves the treatment plant without lead. Lead can enter tap water from older service lines, solder and brass fixtures inside homes, especially when water sits in the pipes. Run the tap before drinking if water has been sitting, and ask the utility about lead testing and service line records.
  5. Is Charleston Water System water hard?
    Hardness depends on the source and changes over time. The annual water quality report lists hardness, or you can test it at home. If it is above about 7 grains per gallon, a water softener sized to your measured hardness will stop scale and spotting.
