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.
Contact the Cross-Connection Control Section at (808) 748-5470 or by email at firstname.lastname@example.org. The fax number is (808) 550-5550.
BWS has suspended offering the backflow prevention assembly tester training course.
