Peachtree Corners businesses are Gwinnett County water and sewer customers, and Gwinnett's backflow program uses testers from its approved list while making owners responsible for the preventer itself. The city, incorporated in 2012, issues its own building and trade permits through BS&A Online. Call the number on this page to be connected with a local plumber in Peachtree Corners.

How Peachtree Corners is set up
Peachtree Corners is Gwinnett's largest city and was planned around Technology Park, with office campuses, The Forum shopping district and the Curiosity Lab test bed along the Chattahoochee. The city lists Gwinnett County Department of Water Resources for water and sewer, including drinking-water problems and main breaks; the county's 24-hour line is 678.376.7000.
Gwinnett draws a clear line on ownership. The county maintains the meter and the small pipe from the main to it. The private water service line, the entire sewer lateral and any backflow preventer belong to the property owner. For office parks with long service runs across parking lots, that means a leak under the asphalt is the owner's to find and fix.
Gwinnett runs the backflow and cross-connection program. Testers come from the county's approved list and submit reports online; questions go to DWRBackflow@GwinnettCounty.com. Our fact sheet's sources don't confirm the testing interval, so check with the county. Permits come from the City of Peachtree Corners Building Division at City Hall on Technology Parkway, which reviews plans, inspects commercial structures and issues trade permits. Most of the city's buildings date from the 1980s and 1990s.

Timing notes
Office campuses are easiest to work on at night or on weekends, when restrooms can be closed. Restaurants at The Forum should schedule grease line cleaning before busy seasons. Exterior hose bibbs, irrigation and backflow devices on landscaped campuses should be protected before a hard freeze.
When you call, you'll be connected with an independent local plumber who does commercial work in Peachtree Corners. Have the building engineer or property manager's contact ready, since shared risers, the water heater room and the main shutoff in multi-tenant offices are usually under their control.
