Backflow & Cross-Connection Control

Backflow is the undesirable reversal of flow of water, liquids, mixtures or substances into the public water distribution pipe system from any source or sources other than its intended source as result of a cross connection. There are many ways when backflow can happen. An example would be when pressure in a property owner’s equipment is greater than the pressure in the drinking water line, or for example, when the pressure in the water line drops and dirty/used water from a home or business gets back siphoned into the public water distribution pipe –that ends up at your water tap!

Backflow prevention is designed to protect the public water supply from contamination from customer’s plumbing systems. Per the Florida Administrative Code (FAC) –Chapter 62-555.360 and Town ordinances, Chapter 25 Article V and Article VIIA, an approved backflow device is required on all commercial, institutional and industrial businesses, multifamily residences, dedicated irrigation lines, and fire suppression lines. In addition, all single family residences with irrigation systems must have an approved testable backflow prevention device installed.
Per Town ordinances, failure to install an appropriate backflow constitutes grounds for discontinuing water service, in order to protect the public water system. 

The Town of Davie has contracted with Backflow Solutions Inc. (BSI) to manage the backflow certification program. Every backflow service must be inspected annually by a certified backflow tester that is registered with BSI. Customers with known devices receive a reminder from BSI that testing is due.

If you have any questions regarding the program, please contact the Utilities Department at 954-327-3742 or BSI (for your existing backflow) at 1-800-414-4990 or visit the website at
