Dacula relies on Gwinnett County for water and sewer, but the city sells its own building permits at City Hall and sends its own inspector, and its gas may come from the City of Buford's system rather than Atlanta Gas Light. Plumber Atlanta is a free call-connection service for independent plumbers, not a plumbing outfit. Call the number on this page to be connected with a local plumber in Dacula.

Plumbing services in Dacula
Gas: check your bill before you need it
The City of Dacula's utilities page lists the City of Buford under natural gas, and Buford's gas department serves parts of Gwinnett and four neighboring counties. Some Dacula-area addresses may instead be on the Atlanta Gas Light system, with a marketer such as Gas South on the bill. Know which you have. If you smell gas, leave the house first and then call 911 and the right utility from outside: the City of Buford at 770-932-7981 during the day or 770-932-7986 after hours, weekends and holidays; Atlanta Gas Light at 877.427.4321 if your bill shows AGL or a marketer; or the City of Lawrenceville at 770-963-3332 if your bill comes from Lawrenceville.
A small city inside a big ZIP
Dacula was incorporated in 1905 and is a small, historic eastern Gwinnett town that is growing quickly, with new shopping along Harbins Road. The city had 6,882 residents in 2020, but ZIP 30019, which also covers unincorporated Hamilton Mill, has more than 51,000. Winder Highway and University Parkway (U.S. 29) are the main roads, and the Elisha Winn House and Little Mulberry Park are local landmarks. It sits about 33 miles from downtown Atlanta.
Water and sewer from Gwinnett
The city has no water department. Gwinnett County's Department of Water Resources supplies Lake Lanier water treated at its Shoal Creek and Lanier plants, and Gwinnett reports the water as soft, at roughly 1 to 2 grains of hardness per gallon. Gwinnett owns the pipes up to the meter; from the meter to the house, everything is the owner's. Its 24-hour dispatch number is 678.376.7000.
Gwinnett also builds and runs sewer lines in Dacula, but some properties are not on municipal sewer and use private onsite wastewater systems. New structures on those lots need approval from Gwinnett Environmental Health (770-963-5132).
City permits and the city inspector
Building permits are picked up and paid for at Dacula City Hall, 442 Harbins Road (770-963-7451), and the City Inspector does inspections with 24 hours' notice. The permit application spells out some of what the inspector checks at plumbing rough-in, such as water piping strapped every five feet and a water test on the waste lines. Whether a standalone water heater swap needs a permit is not spelled out, so ask City Hall.
Housing
Only about 12.5% of Dacula homes predate 1980, and the median year built is 1999. Most service calls involve water heaters, supply valves, fixtures and drains in subdivision homes.
