Plumbing services in Peachtree Corners
Lake Lanier water, soft by the numbers
Water here comes from a different source than in Atlanta. Gwinnett County Department of Water Resources draws from Lake Sidney Lanier and treats it at the Shoal Creek and Lanier filter plants, disinfecting with chlorine and adding fluoride. The county lists average total hardness at about 1.34 grains per gallon, which is low, so a softener is rarely the fix for spotting or scale; a plumber can look for other causes first. Gwinnett's 24-hour line for main breaks and other problems is 678.376.7000.
What the owner is responsible for
Gwinnett maintains the meter and the short pipe from the main to the meter. Everything on the customer's side, including the private water service line, the entire sewer lateral and any backflow preventer, belongs to the property owner. That is a wider share than in some neighboring systems: a root-clogged or broken sewer lateral is the owner's repair all the way to the main.
Backflow devices are tested by testers on Gwinnett's approved list, who submit reports to the county online. Questions go to DWRBackflow@GwinnettCounty.com or 678.376.4213.
Gwinnett's largest city
Peachtree Corners incorporated on July 1, 2012, after a referendum the previous fall, and counted 42,243 residents in 2020, making it the largest city in Gwinnett County. It sits in the county's western corner on the Chattahoochee River, about 18 miles from downtown Atlanta, along Peachtree Parkway, Holcomb Bridge Road and Spalding Drive. Technology Park, The Forum, Peachtree Station and Spalding Corners are familiar names.
Most homes came out of the 1980s and 1990s: the median year built is 1989, about 65% date from 1980 to 1999, and only about 17% are older. At that age, supply lines, fixture valves, water heaters and sewer laterals are the typical service calls.
Permits from the city
Since incorporation, building and trade permits come from the City of Peachtree Corners Building Division rather than Gwinnett County. Applications go through BS&A Online, and City Hall on Technology Parkway answers at 678-691-1200.
Gas, and getting connected
Atlanta Gas Light owns the gas pipes in its metro service territory, though the bill comes from a marketer; confirm the pipe utility on your bill. If you smell gas, leave first, then call 911 and Atlanta Gas Light at 877.427.4321. Call the number on this page with your address and the problem, and you'll be connected with an independent plumber who works in Peachtree Corners.
