GO TO: Cross-Connection Control | Commercial Development | Project Review | Water System Standards

The Cross Connection Control Section (CCCS) of the Board of Water Supply was established to ensure that the public drinking water system is protected from possible contamination through cross-connections and backflow conditions. CCCS manages and oversees the agency's cross-connection control and backflow prevention assembly annual testing program. The program encompasses over 9,000+ private- and government-owned backflow prevention assemblies across the island.

The CCCS also reviews constructions plans for cross-connection control and backflow prevention requirements, conducts cross-connection control inspections of backflow prevention assembly installations, cross-connection control surveys, and addresses any questions or concerns the public may have regarding backflow prevention or cross-connection controls.
