Backflow and Cross-Connection Control Program


Important changes to the City of Margate's Backflow and Cross-Connection Control Program: Effective August 1, 2021, HydroCorp Inc. will be conducting all of the backflow testing for the City of Margate.

Every drinking water system in Florida must have a cross-connection control program, more commonly known as a backflow prevention program. (See Section 62-555.360 Cross Connection Control for Public Water Systems

Backflow prevention is designed to protect the public water supply from contamination from customer’s plumbing systems. For more information about backflow prevention, please visit the Florida DEP site:

Who does this requirement apply to?

Domestic water services that are determined by the City to pose a contamination risk to the drinking water system will require a reduced-pressure backflow (RP).  The RP must be tested by a licensed backflow technician every year (annually).  This applies to locations where the service connection pipe diameters is greater than one (1) inch and for all commercial premises.

All irrigation service meters must be protected by a backflow device as per State of Florida rules (see above).  Only pressure-vacuum breaker (PVB) or reduced-pressure backflow (RP) devices are acceptable.  The testing frequency for commercial irrigation backflows is every year (annually).  

Who is managing the City’s Backflow Program?

Since 2013, responsibility for maintenance and testing of BPA’s has been the owner’s responsibility.  However, under the current system, the City has not been successful in achieving a level of compliance that ensures the public water supply is protected and safe for drinking.  Consequently, the City’s Department of Environmental and Engineering Services (DEES) is embarking on a program to assist property owners to readily comply with the requirements for Cross-Connection Control/Backflow Prevention.

Effective August 1, 2021, the City of Margate is implementing a Backflow Prevention Assembly (BPA) Testing and Maintenance Program to assist business owners test their devices. The City of Margate hired HydroCorp. Inc. to review and qualify BPA testing contractors, and assign BPA testing work through a selection process to certified, licensed, insured and experienced contractors.  The testing will be paid for by the City of Margate and will be billed annually on the water and wastewater bill every October.  The contractor will immediately process all test forms and paper work directly.

If your BPA requires repair or replacement due to a failed test or damage, the contractor will provide you with a notice that will contain a list of contractors who can complete the necessary work.  You will choose who will repair your valve.  The costs for the repair and installation services have also been competitively bid through our program manager, HydroCorp Inc.  You may also choose to find your own licensed plumber or you may contact our program manager to assist you with finding a qualified firm to perform the repairs. Note that the home/business owner is responsible for fees related to the repair or replacement of BPA’s and will pay the contractor directly for such services. Any BPA’s that have failed must be repaired and retested within 30 days of the testing revealing the need for such repairs. 

All of the BPA testing will be coordinated through our program manager, HydroCorp, Inc.  If you have any questions about this program please contact HydroCorp 1.844.493.7660 and ask for Amy.    

Frequently Asked Questions

What if I don’t comply with local, state and federal mandates?

Water service will be terminated to protect the public water system.

What is a cross-connection?

Cross-connection refers to any actual or potential physical connection between a potable water line and any pipe, vessel or machine containing a non-potable fluid or has the possibility of containing a non-potable fluid, solid or gas that could potentially enter the potable water system by backflow.

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.

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.
