Annual or event-based timing
Residential, commercial, and industrial customers when IRWD determines that the potable system may be exposed to contamination through a backflow condition.
- Upon utility notice and annually thereafter
- IRWD says customers will be notified when a backflow assembly is required and points them to a partial list of certified testers who can perform testing in the district.
Non-compliance penalties
IRWD frames backflow protection as a required response when the district identifies contamination risk. The practical penalty is that the water customer cannot ignore the district determination or skip the assembly maintenance requirement.
- IRWD uses a hazard-based utility determination rather than a one-size-fits-all rule.
- The district points to a partial tester list rather than hiding the tester path entirely.
- Residential and commercial hazard cases both appear in the public explanation.
Compliance workflow
Official workflow
Every focused page on this utility still runs through this authority sequence. Confirm the rule here before you branch into repair, testing, or provider routing.
- Wait for IRWD's determination or notice that the service requires an assembly.
- Install an approved assembly type that matches the site hazard.
- Use a recognized certified tester to test and maintain the assembly.
- Keep the annual testing record and district form current once the assembly is in service.
