Plumbing services in Snellville
City inspectors and a local code amendment
Snellville Planning and Development issues building permits and sends its own inspectors; the city building inspector takes requests at (770) 985-3513 or 3514 with 24 hours' notice. Plumbing subcontractors on a permitted job file subcontractor affidavits but pay no separate permit fee. The city has also adopted a local amendment to the plumbing code covering water efficiency requirements, which can affect the fixtures chosen for a remodel. The city's page doesn't say whether a water heater replacement on its own needs a permit, so ask the office before that job.
Gwinnett County water and sewer
Snellville has no water department; its Public Works covers sanitation, stormwater and streets. Building permits require water and sewer tap receipts from Gwinnett County Department of Water Resources, which supplies both. The county draws from Lake Sidney Lanier, treats it at the Shoal Creek and Lanier plants, disinfects with chlorine and adds fluoride. Hardness averages about 1.34 grains per gallon, so the water is soft. Gwinnett's 24-hour dispatch is 678.376.7000, and billing is 678.376.6800.
Gwinnett maintains the main and the meter. Everything on the customer's side of the meter, plus the entire sewer lateral and its connection to the county sewer, is the owner's to repair. The county's service line inventory can be searched at GwinnettCounty.com/ServiceLines.
An established south Gwinnett suburb
Chartered by the Georgia General Assembly in 1923, Snellville sits on US 78 in southern Gwinnett County, about 23 miles from downtown Atlanta, with State Route 124 and Lenora Church Road as other main routes. It had 20,573 residents in 2020 and keeps a small-town feel, with the Snellville Days festival and plans for a new town center. Piedmont Eastside Medical Center and the Nob Hill neighborhood are familiar names. The median home was built in 1991, and roughly 30% predate 1980. That older third of the housing is where aging supply lines and laterals turn up most; in 1990s subdivisions, water heaters, valves and toilets lead the list.

Snellville has no city gas department, and Atlanta Gas Light is the gas operator listed for Gwinnett County. If you smell gas, leave the area, then call 911 and Atlanta Gas Light at 877.427.4321 from a safe place.
