Backflow Department

The purpose of the SCPW backflow and cross connection control program is to protect and maintain the public water system such that it is free from potential hazards to the health of its customers, and such that safe and potable water in sufficient quantity and pressure is delivered.

The program has been implemented to eliminate and/or control any existing and potential unprotected cross connections between the water supply system and any other water systems, sewers, drain lines, piping systems or containers containing possible contaminants.

Backflow Assemblies are required to be tested annually by a certified tester to help ensure the device is functioning properly. Click here for a list of Certified Testers. Property owners are responsible for repairing or replacing any backflow assemblies that fail to meet performance standards.

Testers are required to submit a copy of their test results to Summerville CPW electronically via Backflow BMP.
