Butner's water and sewer come from the South Granville Water and Sewer Authority, which is headquartered in town, and Granville County Inspections handles building permits. The Town itself does not run water or sewer service. Call the number on this page to be connected with a local plumber in Butner.

Butner in brief
Butner grew from the World War II-era Camp Butner, and its streets still follow that grid, many of them numbered or lettered. Today it is a small Granville County town on I-85 between Durham and Oxford with large state and federal institutions nearby. Housing is mostly from the 1980s through the 2000s, with a median build year of 1991 and about 29% built before 1980. SGWASA, at 415 Central Avenue, serves about 6,600 customers in Butner, Creedmoor and Stem, treating water from Lake Holt and sending wastewater to its plant in Butner. In January 2026 it began an I-85 sanitary sewer improvement project in southern Granville County near the town.
What to do when there's a problem
- Close the private cut-off valve. SGWASA rules require the customer to keep one on the building side of the meter. Make sure staff know where it is and that it actually turns.
- Protect people and equipment. Keep customers away from wet floors and shut off power to anything standing in water.
- Figure out the scope. Note whether one fixture, one suite or the whole building is affected.
- Check backflow paperwork. Irrigation, treated pools and spas, fire sprinkler lines and multi-family units sharing one meter all need backflow protection under SGWASA's ordinance, tested every year.
- Call for help and have hours ready. Know when the space can be shut down for work.
Symptoms and what they usually mean
| Symptom | Likely cause |
|---|---|
| Discolored water building-wide after nearby hydrant use | Iron and manganese stirred up in the mains, which SGWASA calls aesthetic |
| Discolored water in one area only | Interior pipe or a water heater needing a flush |
| Water bill climbing with no change in use | A running toilet, a dripping fixture or a leak between the meter and building |
| Backups on the lowest level | A partial blockage in the building drain or lateral |
| Banging pipes after valves close | Water hammer or a failing check valve |
What affects the cost
- The number of fixtures, units or tenants involved
- Backflow assembly repairs if a yearly test fails
- Off-hours scheduling to keep a business open
- Camera work or leak locating to find the source
- Granville County permits, since the county handles building permits for Butner while the Town keeps its own zoning
