AWWA REUSE52141

For almost thirty years, San Antonio has enforced cross connection control andbackflow prevention measures as established by the University of SouthernCalifornia's Foundation of Cross Connection Control and Hydraulic Research,American Water Works Association's M-14 Cross Connection Control Manual and localplumbing codes. There have been a number of documented backflow incidents thathave involved many different waters using equipment and processes. The number andseverity of documented incidents in San Antonio have steadily decreased due inpart to stringent enforcement of the cross connection program. In the last fewyears, the San Antonio Water System (SAWS) has designed, started construction andmet our first customer commitment for Recycle Water which will assist inrelieving future water concerns. A large water main will encircle the city andprovide water for irrigation, industrial processes and special water usingequipment. The services will generally be 4" and larger due to the typical sizeof our recycle customer needs. As with any cross connection control measures,backflow prevention is a continuous effort with recycle water and is initiatedprior to water service being provided to the customer. The SAWS BackflowPrevention Section and the San Antonio Plumbing Inspection Department are chargedwith assuring separation of the potable water supply from processes beingprovided with recycle water. This paper discusses some of the policies andprocedures that have been established to prevent recycle water cross connectionsin San Antonio.
