Backflow Requirements


The South Carolina Department of Health and Environmental Control (SCDHEC) requires all public water systems to maintain a viable cross connection control program per the State Drinking Water Regulation R.61-58.7 (F). The cross connection control program is part of the Drinking Water Protection Program.

The regulation was amended April 29, 2005 to address backflow prevention requirements for low hazard residential lawn irrigation systems. The amendment requires LCWSC to determine the type of backflow device required for residential lawn irrigation systems and implement a change out period for the backflow device.

The Laurens County Water and Sewer Commission maintains a viable cross connection control program (CCCP) to comply with the regulation and prevent the backflow of contaminated water into the LCWSC water system. The program includes policies for installation of residential dual check valves on all services, and installation of testable backflow devices on all commercial or hazardous services.
