Woodstock runs its own water and sewer utility, blending purchased surface water with city-treated groundwater, and requires a plumbing permit separate from any building permit. Plumber Atlanta is a free referral service that connects callers with independent plumbers. Call the number on this page to be connected with a local plumber in Woodstock.

Plumbing services in Woodstock
Three sources in one tap
The City of Woodstock Water & Sewer Utility, part of Public Works, buys treated surface water from two authorities, the Cobb County-Marietta Water Authority and the Cherokee County Water & Sewerage Authority, drawing on the Chattahoochee River, the Etowah River and Lake Allatoona. It also pumps and treats groundwater at five city facilities. All three supplies are disinfected with chlorine, and the city has installed carbon filtering systems designed to further reduce PFAS in its treated water. Its report says the water met all federal and state requirements and does not list hardness, so test before buying a softener. The city has also published a lead service line inventory, which is worth checking if you are planning to replace the line from the meter to the house.
The same utility handles sewer. Business-hours billing and emergencies go to 770-592-6006, and after-hours emergencies to 770-926-7871.
Built mostly since 2000
Woodstock was incorporated as a town in 1897, a railroad stop marked today by the 1912 Woodstock Depot, and it has since become one of the fastest-growing suburbs in metro Atlanta. It had 35,065 residents in 2020 and sits in Cherokee County about 25 miles north of downtown Atlanta, near the Little River and trails such as Noonday Creek, Trestle Rock and Serenade. The median home dates from 2005 and fewer than 7% predate 1980. In houses that young, the calls are mostly first water heater replacements, PEX and fitting leaks, fill valves, disposals and clogged drains, rather than failing old pipe.
A separate permit for plumbing
Woodstock Community Development's Building & Safety Division states that plumbing needs its own permit apart from the building permit, and it inspects plumbing under the 2024 International Plumbing Code with Georgia amendments. Under-slab plumbing inspections are scheduled under the plumbing permit number. The division answers at 770-592-6000, extension 1500.
Gas
Atlanta Gas Light is the gas operator listed for Cherokee County; residents buy gas from marketers, so the name on the bill may not be the company that owns the pipe. Smell gas? Leave the house, then call 911 and Atlanta Gas Light at 877.427.4321 from outside. A plumber can repair or extend gas piping inside the home once the utility has dealt with any leak.
Compared with Atlanta
A Woodstock house gets a blended supply that includes city well water, from a city utility in another county, and its plumbing permit is issued by Woodstock. Call the number on this page, explain what's happening and you'll be connected with an independent plumber who works in Woodstock and sets the price with you.
