Serves Most of West Valley City, UT (about 75 percent per the city's water element). Every point below comes from Granger-Hunter Improvement District's own pages, linked; check your notice for your own deadline.
Who must test
- Any backflow prevention assembly tested by an independent laboratory and accepted by the Utah Division of Drinking Water may be used, as long as it fits the degree of hazard at the facility. Source.
- Facilities should have a registered licensed professional engineer use the Division of Drinking Water rules to set the hazard level and the matching assembly. Source.
- A check valve cannot be used as a backflow prevention assembly because it has no test connections. Source.
Notices and deadlines
- GHID plans to install a backflow device at every one of its 27,500+ connections and will send a letter giving 30 days' notice before installing one at a meter (except emergency repairs). Source.

- Will you send the test report to the utility for me, and how?
- When is my report due? The date is on your notice; the tester needs time to test, repair if needed and file.
