Residential Cross Connection Control and Backflow Prevention


Cross Connection Control Prevention

JEA’s Cross Connection Control Program is committed to protecting our drinking water supply from contamination. Our goal is to eliminate all cross connections and all potential and real paths to contamination in our service area.


A backflow event is almost always initiated by accident or unexpected circumstances. Backflow can be controlled by good design, proper maintenance, and following the guidelines of the JEA Cross Connection Control Program.

Customer Responsibility 

The customer’s responsibility starts at the point of delivery from the public potable water system. That point is immediately after the water service meter, or in the case of unmetered services, where the water service enters the customer’s property. The customer is required, at their expense, to install, operate, test, and maintain approved backflow prevention assemblies. Backflow preventers must be installed by certified plumbers and tested by properly certified JEA Qualified Vendors. The JEA Qualified Vendors submit the test results to JEA on behalf of the customer. In the event of accidental pollution or contamination of the public drinking water system due to backflow, on or from the customer’s premise, the customer must immediately take steps to confine further spread of pollution or contamination and notify JEA of the hazard at 904-665-6000.  


JEA and JEA contracted vendors shall have free access to the premises of any user of its water supply for the purpose of inspecting, and/or testing any backflow device directly connected to JEA’s water system, or to inspect the premise to determine if there are any cross connections. Backflow preventers must be installed so that they are easily accessible for inspection, testing, maintenance, and repair. 


In most cases, a cross-connection to the public water supply is eliminated by the presence of an approved backflow preventer.

3Residential dual check devices can be added if there is a customer agreement signed stating that no cross connection will be created from the reclaim system to the potable water system, or they are managed by a third party where the customer is prohibited from tampering with the facility’s potable water system, auxiliary water system, or reclaimed water system. Residential dual checks must be replaced every 5 years

Inspections and Interruption of Service

Failure to respond to notices of violation will result in a site compliance inspection by JEA. JEA will assess a $100 inspection fee on the bill of the customer of record.

JEA will discontinue water service if the required backflow prevention assembly is missing, bypassed or failed to be tested or properly maintained per JEA’s CCC Policy.

Additionally, JEA may install, test, repair, or replace a backflow device at the customer’s point of service and bill the customer for all costs associated.
