As part of the City’s Cross-Connection Control Program, the Water Division installs backflow prevention assemblies at the water meters in neighborhoods with reclaimed water service.
A backflow prevention assembly is a specialized mechanical device designed to protect the public drinking water supply. It prevents contaminants or pollutants from flowing backward from private plumbing systems into the City’s water system.
These devices are manufactured to meet national industry standards established by organizations including the American Water Works Association, the American Society of Sanitary Engineers, and the Foundation for Cross-Connection Control and Hydraulic Research.
To ensure they continue operating properly, each backflow prevention assembly is tested annually. If a device is found to be malfunctioning, Water Division staff will repair or replace it at no cost to the customer.
In addition, Water Division staff perform annual inspections of reclaimed water irrigation systems and drinking water plumbing to verify the two systems remain separate and that no cross-connections have occurred.
