Who does this requirement apply to?
Below is a list of facilities that require a backflow prevention device. This list is presented as a guideline and is not to be construed as encompassing all commercial properties requiring a backflow prevention device.
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?
Contact the Marion County Utilities cross-connection control program at 352-307-4630 or via email at CrossConnectionControl@marioncountyfl.org.
Thank you for doing your part in protecting the public water supply and adhering to this requirement.
