Backflow Testing in Suwanee, GA

Suwanee's water comes from Gwinnett County Department of Water Resources, which names any backflow preventer as the property owner's responsibility. Tests are done by testers on the county's approved list, and reports are submitted online. The pages we reviewed don't confirm an interval. Call the number on this page to be connected with a local plumber in Suwanee.

Local conditions in Suwanee

Suwanee grew from a small railroad town into a north Gwinnett suburb known for Town Center Park and its greenway trails, and most of its housing was built after 1990. The city's utilities page lists Gwinnett County DWR for water and sewer, with no city-owned water system.

Gwinnett is unusually clear about who owns what. The county maintains the meter and the small pipe from the main to it. Everything on the customer's side, including the private service line, the entire sewer lateral and any backflow preventer, is the property owner's responsibility. Under the county's backflow and cross-connection program, devices are tested by people on Gwinnett's approved tester list, and test and maintenance reports go to the county online. We couldn't confirm the testing frequency from the county pages reviewed, so ask DWR's backflow staff at 678.376.4213 or DWRBackflow@GwinnettCounty.com.

Newer subdivisions along Lawrenceville-Suwanee Road and near Sims Lake Park commonly have in-ground irrigation, which is the usual reason a Suwanee home has a backflow preventer at all.

Seasonal notes

Have the preventer checked when irrigation starts in spring and before you shut the system down in fall. Suwanee requires permits for changes to plumbing systems, with applications and inspection requests handled online through the city's permit portal. When you call, mention whether the preventer sits above ground or in a box, and have any county letter ready so the plumber knows exactly what Gwinnett asked for.
