Protecting the public drinking water system from harmful contaminates is a shared responsibility. The City's Backflow Prevention Program coupled with the private installation and maintenance of approved backflow prevention devices serves this purpose.

ALL Non-residential property owners with City water service are required to install and maintain an approved reduces pressure zone (RPZ) backflow prevention device.
ALL residential property owners are required to install and maintain an approved backflow prevention device if their premises contain an actual or potential Cross-Connection such as a well, irrigation system or swimming pool have an identified hazard such as a swimming pool, irrigation system, well or fire line. Please check the cross connection manual to see if you need a device at your residential location.
Property owners with backflow prevention devices are required to regularly test their backflow devices and submit certified test results from Certified Backflow Testing Professionals to the Utilities Department Backflow Prevention Program Administrator at the email below.
Certified testers are responsible to comply with the standards of the utility.
