Preventing contaminated water from re-entering our drinking water

Backflow assemblies prevent the drinking water inside homes and businesses from flowing backward into the drinking water system, keeping contaminated water out of the drinking water system.

Property owners

All new installations, replacements and relocations at a Hillsborough County Public Utilities water service connection require a permit. Visit the HillsGovHub permitting portal to start the process. All work must meet all current plumbing codes and Water Resources department technical specifications. The permit holder is responsible for scheduling the backflow preventer field inspection and submitting a backflow test report. Email the completed backflow test report the contact information below for permit inspection approval and permit closure. Once these requirements have been reviewed and approved the permit will be closed.

Submit results

Submit test results using the Backflow BMP portal. You must notify the County within 48 hours of any backflow preventer assembly that fails a test.
