Utilities - Backflow Prevention Program

1. What is backflow?: 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.

2. What is a cross-connection?: Cross connection means any physical connection or arrangement of piping or fixtures between two (2) otherwise separate piping systems, one (1) of which contains potable water and the other non-potable water or industrial fluids, through which, or because of which, backflow or backsiphonage may occur into the water system.

3. Who does this requirement apply to?: Backflow prevention devices are required on all commercial, industrial, institutional businesses, multifamily residences, dedicated irrigation lines, fire suppression lines and auxiliary water systems (reclaimed, lake, canal, etc.). This list serves as a guideline only. A comprehensive listing is provided in the Town of Davie Ordinance, Chapter 25 Article V and Article VIIA.

4. When might backflow occur?: Inadequate plumbing and events such as water main breaks or fire hydrant use can contribute to backflow conditions. Backflow may also occur when pressure in the property owner’s equipment is greater than the pressure in the drinking water line.

5. What are my responsibilities?: It is a requirement that every backflow device must be inspected annually by a certified backflow tester who is registered with BSI. Backflow prevention inspectors shall submit inspection results to BSI as part of their service. The results of the inspection must be submitted to BSI Online.

6. How do I comply with these requirements?: Customers with known devices will receive a notification and reminder directly from BSI that recertification is due. Once the inspection is complete, the testing company will enter that information directly into BSI’s online reporting system.
Customers who are in the process of modifying their plumbing and are in need of a backflow device, must contact the Building Division at 954-797-1111 for the relevant permits and inspections. Once the inspection is completed, the backflow certification report will be uploaded and registered in the BSI system. Subsequent recertifications will be sent from BSI.
If you have any questions regarding the program please contact Heidi Klemm with the Town of Davie Utilities Department at 954-327-3741 or BSI at 800-414-4990.

7. What if I don’t comply?: Failure to install an appropriate backflow device or have the device recertified constitutes ground for discontinuing water service, in order to protect the public water system.

8. Who is managing the Town’s Backflow Program?: The Town of Davie has contracted with Backflow Solutions Inc. (BSI) to manage the backflow certification process. BSI has experience managing similar programs for other municipalities across the country. All certifications for backflow compliance must be entered on-line through BSI’s website by the BSI certified plumber/backflow tester. BSI will serve as the primary point of contact for backflow inspections within the Town of Davie and can be contacted at 800-414-4990 or through their website.

9. What is a backflow prevention assembly?: Backflow prevention assemblies are designed to prevent contaminated water or chemicals from a property flowing back into the public drinking water supply system.

10. Why are backflow prevention assemblies required?: Backflow prevention assemblies are an important component of the Town’s drinking water protection program and are legally mandated under Florida rules for those water service lines identified as posing a risk to the public water supply.

11. What is the cost of backflow prevention assemblies?: Installation costs vary depending on the assembly and selected licensed plumbers' labor costs. The Town also requires a plumbing permit to install these devices. The investment to install and maintain the assembly is minimal compared to the potential public safety hazard and liability of a backflow incident. It is a State requirement in order to protect the potable water supply for everyone.

12. Who can install a backflow prevention assembly?: - Domestic backflow assemblies - licensed plumbing contractor. (Plumbing Permit required)

- Lawn irrigation backflow assemblies - licensed plumbing or lawn irrigation contractor. (Plumbing Permit required)

Fire service backflow assemblies must be tested by a licensed fire inspection company which is also certified for backflow testing.
