Preventing contaminated water from re-entering our drinking water
Hillsborough County is migrating to a new platform, Backflow BMP, for backflow test submittals. Due to Hurricane Milton, both the Teams meeting for testers that was scheduled on Tues. Oct. 8, and the go live date for the new platform scheduled on Oct. 14, are postponed and will be rescheduled for a date to be determined.
Backflow assemblies allow potable water to move in only one direction to the point of delivery, preventing contaminated water from re-entering our drinking water.

Common questions you may have about testing.
Do I have to get my backflow assembly tested?
