Unlike most towns near Raleigh, Selma's main water system runs on groundwater from its own wells, and over half its homes predate 1980. Plumber Raleigh NC connects callers with independent plumbers; it is not a plumbing company. Call the number on this page to be connected with a local plumber in Selma.

Plumbing services in Selma
Selma is a Johnston County town of about 6,300 people, chartered in 1873 and built around the railroad. Its Union Depot still serves Amtrak. The town sits next to Smithfield, about 25 miles from Raleigh as the crow flies, where I-95 crosses US 70, with US 301 and NC 96 running through. The 27576 ZIP covers roughly 21,600 residents.
Two water systems in one town
Most of Selma drinks groundwater pumped from town wells and disinfected with chlorine rather than chloramine. That's a real difference from Raleigh, where Raleigh Water uses chloramine most of the year. A separate Selma-Countyline system delivers surface water bought from Johnston County East. The town doesn't describe which streets are on which system, so check your bill if it matters for a filter or treatment question.
The 2025 water quality report covers both. The main system's lead sampling found the 90th percentile not detected, though the town received a violation related to its lead service line inventory reporting. The Countyline system exceeded the limit for total trihalomethanes, a disinfection byproduct, with a running average of 93 ppb against an 80 ppb limit. If you're on Countyline, the report explains what that means and what the town is doing; it's worth reading rather than guessing.
Hardness isn't reported for Selma's wells, so if you're thinking about a softener, a plumber can test your water first.
Sewer and lift stations
The town maintains its own collection lines and 19 sewer lift stations, and Johnston County treats the wastewater through its interceptor to the central regional plant. A backup at a single drain usually points to your own line; several drains backing up at once, or a problem shared by neighbors, is worth reporting to the town's water and sewer operations too.
Older houses
The median Selma home dates to 1974, and about 55% were built before 1980. In the Downtown and West Selma historic districts, plan on older drain lines and supply pipe that may have been partly replaced over the years.
Permits and gas
Start with zoning approval from the Town of Selma planning department (919-965-9841), then go to Johnston County Building Inspections in Smithfield (919-989-5060). We didn't find a published backflow testing program for Selma.
Piedmont Natural Gas covers Johnston County, but not every street has a line. Smell gas? Step outside first, then call 911 or Piedmont's emergency number, 800-752-7504.
