The Cross Connection Control Section (CCCS) of the Board of Water Supply (BWS) 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 6,300 private- and government-owned backflow prevention assemblies across the island.

In addition to managing the backflow prevention assembly annual testing program, the CCCS reviews constructions plans for cross-connection control and backflow prevention requirements, conducts field inspections of backflow prevention assembly installations, and addresses any questions or concerns the public may have regarding backflow prevention or cross-connection controls.
