The Town of Butner does not run water or sewer; the South Granville Water and Sewer Authority (SGWASA), headquartered in Butner, handles both. Plumber Durham is a free service that connects you with independent plumbers and does no plumbing itself. Call the number on this page to be connected with a local plumber in Butner.

Plumbing services in Butner
From Army camp to town
Butner began as Camp Butner, a U.S. Army post from 1942 to 1947, and the State of North Carolina ran it until it incorporated as a town on November 1, 2007. Its streets still follow the old camp grid, with many numbered and lettered roads off Central Avenue. It sits in southwestern Granville County about 13 miles north of downtown Durham in a straight line, with I-85 exits 186, 189 and 191. The 2020 Census counted 8,397 residents. Large institutions, including the Federal Correctional Complex and Central Regional Hospital, are major neighbors.
Water from Lake Holt
SGWASA draws water from the R.D. Holt Reservoir northwest of town and treats it at its own plant. Chlorine is added during filtration and chloramine is the final disinfectant. The 2025 report shows no violations, a 2024 lead 90th percentile of 3 ppb with no sites over the action level, and no hardness figure. SGWASA also publishes a service line inventory online.
ABC11 reported in early 2025 that SGWASA water was above the new EPA PFAS threshold. SGWASA is running a pilot study of treatment methods, including granular activated carbon, anion exchange and reverse osmosis, ahead of the 2029 federal deadline; its board said the water currently meets state and federal rules and that in-home filters are up to residents. If your water turns brown or yellow, SGWASA attributes that to iron and manganese stirred up in pipes and calls it aesthetic.
The valves SGWASA expects you to keep
This is where Butner differs from Durham in day-to-day plumbing. SGWASA owns the service line up to the property line and the meter. On the house side, the owner must maintain a private cut-off valve plus a check valve or backflow preventer, and keep the service pipe protected from frost. Homes with lawn irrigation or a chemically treated pool or spa need a backflow assembly tested within 10 days of installation and every year after by a state-certified tester, with results sent to SGWASA. Multi-family units sharing one meter need protection too.
Houses, permits and sewer
Butner's median home dates to 1991, a little older than Durham's, and about 29% were built before 1980. Granville County's permit guidance lists Butner among the places it handles, with the Town doing zoning. Sewer goes to SGWASA's treatment plant on Knap of Reeds Creek, and in January 2026 SGWASA started an I-85 sanitary sewer improvement project near Butner.
