Why backflow testing is required in Riverside
Riverside Public Utilities (RPU) and Western Municipal Water District (WMWD) enforce strict cross-connection control programs to protect the potable water supply.

The Riverside area faces unique challenges. The city’s historic downtown district has aging water mains that experience pressure drops during peak usage. Meanwhile, newer developments in Eastvale and Corona sit at varying elevations, creating pressure differentials that stress backflow devices.

Frequently asked questions about Riverside water safety
What happens if I miss the backflow testing deadline?
RPU sends a compliance notice 30 days after the due date. If you don’t respond within 60 days, they may shut off your water service until the testing is completed and the fee is paid. We offer emergency testing services to help businesses avoid service interruptions.
How much does RPU charge for filing test reports?
Riverside Public Utilities charges $25 per device for test report filing. Western Municipal Water District charges $20 per device. These fees are separate from the testing service cost and are paid directly to the water district.
Do I need backflow prevention if I have a well?
Yes. Any property connected to the municipal water supply must have backflow prevention, regardless of whether you also have a well. The device protects the public water system from contamination originating on your property.
How long does testing take?
Most residential tests take 15-20 minutes. Commercial devices with multiple test cocks may take 30-45 minutes. We schedule appointments to ensure we have adequate time for thorough testing and any necessary repairs.
Can I test my own backflow preventer?
California law requires backflow testing to be performed by a certified backflow prevention assembly tester. These technicians must complete specific training and pass certification exams. DIY testing is not permitted and could result in fines.
What’s the difference between a backflow preventer and a check valve?
A check valve allows water to flow in only one direction but provides no protection against backpressure or backsiphonage. A backflow preventer is a more sophisticated device with multiple check valves and often a relief valve, designed to protect against all types of backflow conditions.
