Newnan Utilities requires a backflow preventer on irrigation systems and many commercial uses, and each device must be tested when installed, every year, and any time it is moved or repaired. Newnan Utilities does not do the testing itself, so you hire a certified tester. Call the number on this page to be connected with a local plumber in Newnan.

Signs it's time to call
- A yearly test date that has passed or is coming up
- A new irrigation system that hasn't had its first test
- A device that was repaired or moved and needs a fresh test
- Water leaking from the preventer when the system is off
- A restaurant, car wash or medical office opening in a Newnan building
How Newnan Utilities handles backflow
Newnan Utilities provides electric, water and wastewater service in the city, and it runs its own Backflow Prevention program. The list of properties that must have a preventer is broader than at many utilities: irrigation systems, commercial properties, fire sprinkler systems, medical facilities, car washes and restaurants are all named.
Testing happens at three points: when the device is installed, once a year after that, and any time it's relocated or repaired. Only someone with current Backflow Prevention Certification may do it. Newnan Utilities doesn't test devices itself; reports go in through its online submission system.
Newnan's housing is newer than most of the metro, with a median build year of 2004, and many of the subdivisions off I-85 and around The Forum at Ashley Park came with irrigation. Older homes near the historic downtown are less likely to have a device unless sprinklers were added later. Some addresses in the 30263 and 30265 ZIPs fall outside Newnan Utilities' service area, so check your bill if you're near the edges.
Inside city limits, the City of Newnan Building Department administers the plumbing code and issues permits from City Hall on LaGrange Street.
What affects the cost
- Install test, annual test or post-repair test
- Rebuild parts if the device fails
- Type and size of the preventer
- Number of devices, such as irrigation plus a fire line on a commercial property
- Permit steps for a new or relocated device
What happens when you call
You'll be connected with an independent plumber who serves Newnan. Say what kind of property it is, what the device protects and whether it's leaking. Ask if they hold current backflow certification and can submit the report to Newnan Utilities online. If water is spraying, close the irrigation valve and leave the house supply on.
