Backflow and Cross-Connection Control Program

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

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.

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.

Why are backflow prevention assemblies required?

Backflow prevention assemblies are an important component of the City’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.

What is the cost of backflow prevention assemblies?

Installation costs vary depending on the assembly and selected licensed plumbers' labor costs. The City 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.

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

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