Clayton buys its water from Johnston County and treats much of its own wastewater, and the Town issues plumbing permits inside its limits and ETJ.

- Hot water running out partway through the day
What's local about commercial plumbing in Clayton
Clayton is a fast-growing town on I-40 and the US 70 Clayton Bypass, and most of its buildings are new: the median home was built in 2006, and only about 10% predate 1980. Commercial space runs along US 70 Business, near downtown and out toward Riverwood.
The Town of Clayton Public Works buys all of its water from Johnston County Public Utilities and distributes it through two separate systems, one for the Riverwood area and one for the rest of town. The water is Neuse River water, fairly soft at about 32.5 ppm hardness, with both chlorine and chloramine reported.
On the sewer side, Clayton's Sam's Branch Water Reclamation Facility (formerly Little Creek) treated about 596.7 million gallons in FY2024-25, and the Town also sent flow to Johnston County and to Raleigh for treatment, plus reclaimed water to Pine Hollow Golf Course.
Backflow devices in Clayton must be tested every year by a certified tester. You hire a registered tester, who submits results through BSI Online, and BSI mails a notice 30 days before the due date.
What affects the cost
- Scope. A single restroom versus a main line that serves a whole building.
- Scheduling. Early, late or weekend work costs more but keeps you open.
- Equipment. Jetting and camera work add cost and often prevent repeat calls.
- Permits. Added fixtures, remodels and commercial water heater work bring permit and inspection time.
