[ARCHIVED] New Rules for Vacuum Breakers on Irrigation Systems

In July 2010 the North Carolina Department of Natural Resources, Public Water Supply Section revised the Rules Governing Public Water Systems. Appendix B, Figure 2, III B.1. of the newly adopted version requires that all lawn irrigation systems be protected by reduced pressure backflow preventers. In the past CFPUA has allowed pressure vacuum breaker backflow assemblies to be installed on lawn irrigation systems as long as there were no booster pumps connected to the irrigation system. Since the new rules regulate CFPUA’s cross connection control program, pressure vacuum breakers will no longer be allowed to be installed on irrigation systems. The only type of backflow preventer that will be allowed is a reduced pressure backflow preventer. If you have questions about this new requirement, contact the Community Compliance Section at (910) 332-6558.
