What are my Responsibilities?
It is a requirement that every backflow prevention device be inspected annually by a certified backflow tester. The results of the inspection must be submitted to the Marion County Utilities’ backflow and CCC coordinator. It is common for backflow prevention device testers shall submit the annual inspection results to Marion County as part of the inspection service.
How do I comply with these requirements?
Customers with a known device will receive a notification and reminder directly from Marion County Utilities that testing is overdue. Once the annual inspection is complete, the testing company will submit the completed test result to Marion County Utilities.
Note: backflow prevention devices are added to the county database once inventoried and tested.
Need to submit an initial or annual test result?
