Backflow Prevention Program

One of the goals of the Utility Services Department is to ensure everyone in Boca Raton receives safe drinking water. Backflow is the undesirable reversal of flow of a liquid, gas, or other substance in a potable water distribution piping system as a result of a cross-connection. Potable water services for properties where certain types of activities occur are required to have backflow prevention devices installed, maintained, and tested in order to protect the public water supply from contamination or pollution due to backflow or back-siphonage.

Back-siphonage is a type of backflow where the upstream pressure to a piping system is reduced to a subatmospheric pressure. Utilizing backflow prevention devices prevents backflow or back-siphonage from occurring.

City Code


Per the City of Boca Raton Code of Ordinance No. 17-194: “It shall be the duty of the customer-user at any premises where backflow prevention devices are installed to have certified inspections and operational tests made at least once a year.” Customers help ensure the safety of our water by complying with the annual inspection requirements for their backflow prevention devices.  More detailed information is found in the City of Boca Raton Cross-Connection and Backflow Prevention Policy.

Submitting Test Results


Results of the required annual inspection must be submitted online to Backflow Solutions Inc. (BSI). The City of Boca Raton has contracted with BSI to manage the administrative tasks of the backflow inspection program. BSI will serve as the primary point of contact for backflow inspection information within the City of Boca Raton and can be contacted at 800-414-4990 or through their website. The Utility Services Department is responsible for managing the program, enforcement actions, and billing.
