Backflow

JEA’s Cross Connection Control policy is mandated by the Florida Department of Environmental Protection to safeguard the public drinking water supply from contamination. Cross connections can occur anywhere the public water supply is connected to any other source. These cross connections pose a hazard if water that has been delivered from a different source enters into the public water supply. Cross connections can also occur if water delivered from the JEA line comes in contact with chemicals or other pollutants. This can occur due to accidental backflow or back siphonage of potentially contaminated water and it’s a big problem when that water re-enters the JEA water supply. A backflow prevention device is used to protect public drinking water supplies from this potential contamination or pollution.

In 1990, the City of Jacksonville Building Inspection Division began requiring the installation of backflow preventers on all commercial fire sprinkler service lines, irrigation lines and potable (drinking) water lines.

In addition, JEA’s Cross Connection Control Policy requires the installation, maintenance and annual testing of backflow preventers on all commercial fire sprinkler service lines, irrigation lines and potable (domestic) water lines.

Backflow Preventer

Installation

Backflow preventers are required to be installed on a customer’s property within 10 feet of the JEA meter, or fire line service, and in accordance with manufacturers’ instructions for the specific application. Any variance from installation requirements must have prior approval by JEA.

Are all customers required to have backflow prevention assemblies? 

Requirements for backflow assemblies are determined by the degree of hazard present at a customer’s premise. For example, customers with in-ground irrigation systems or auxiliary sources of water must have a backflow assembly. When reclaimed, well or pond water is present, backflow assemblies are required on the JEA drinking water line to prevent entry of water from those auxiliary systems into the public drinking water supply. Likewise, in-ground irrigation systems utilizing a JEA irrigation or domestic water service are required to have backflow protection on the water supply line.

Testing and Maintenance

Backflow prevention assemblies are subject to corrosion, which can lead to failure.Testing and maintenance of backflow prevention assemblies is required to ensure proper functioning of the assemblies and the safety of our water supply.

  • Install and maintain the backflow preventer. Find a JEA Preferred Vendor. 
  • Residential assemblies must be tested once every two years by a certified backflow prevention assembly tester. 
  • Commercial assemblies must be tested every year by a certified backflow prevention assembly tester. 
  • If the assembly fails, it must be repaired or replaced and tested again to ensure it functions properly. 
  • Upon successful completion of the test, submit a Backflow Assembly Test Report to the JEA Cross Connection Control program. Certain vendors will submit reports to JEA for their customers. 
  • The assembly must successfully pass the test. JEA vendors are required to provide a copy of the test reports to JEA and the customer.
  • All costs associated with backflow prevention assembly maintenance are the responsibility of the customer.

JEA water customers who also use water from an auxiliary water source (any water supply other than the JEA system) including wells, ponds and lakes – must have an approved backflow prevention device on the JEA domestic water service(s) to protect the public water system from possible contamination.
Using Auxiliary Water Sources  

Areas with irrigation systems utilizing reclaimed water must have an approved backflow prevention device on their JEA domestic water service(s) to protect the public water system from possible contamination. 
Using Reclaimed Water for Irrigation

In-ground irrigation systems using potable water (JEA irrigation service or JEA domestic service) must have an approved backflow prevention device on the irrigation supply line to protect the public water system from possible contamination.
Using Potable Water for Irrigation  

JEA customers with wet pipe fire sprinkler systems must have approved backflow preventers. Still water in the fire sprinkler pipes dissolves pipe walls and can introduce metals into the water. Backflow preventers keep these metals from entering the public water system.

Backflow preventers can be classified depending on their function and location. Containment assemblies protect the public water supply and are located within 10 feet of the JEA water meter. Isolation assemblies are internal and primarily protect the customer’s water system by isolating potential hazards in one area.

JEA and the City of Jacksonville Building Inspection Division require installation and maintenance of backflow prevention devices on commercial water service lines. Backflow preventers have been required by the building code since 1990.

Replacing failed backflow preventers requires consideration of risk and water use.

JEA customers who must provide a continuous supply of potable water frequently install two blackflow preventers in parallel. Hospitals and medical facilities are examples where parallel installations are appropriate.
