Siler City's water and sewer utility is now part of TriRiver Water, and Chatham County Central Permitting and Inspections issues plumbing permits inside the town. About half of the town's buildings predate 1980, and the wastewater plant has been under a state consent order. Call the number on this page to be connected with a local plumber in Siler City.

Siler City at a glance
Siler City is a western Chatham manufacturing town built around poultry processing, with a commercial historic district downtown and the East Raleigh Street and North Third Avenue historic neighborhoods nearby. The median home dates to 1980 and roughly half are older, with a large 1950s share, so many storefronts and rentals have galvanized supply pipe or cast-iron drains that have been patched more than once. Water comes from the Rocky River and Charles L. Turner reservoirs through the Siler City filtration plant, which TriRiver Water now runs.
What to do when something fails
- Stop the water. Close the fixture valve or the building's main shutoff if a pipe is leaking. Make sure at least one staff member knows where it is.
- Keep people away from wet areas. Water around outlets, equipment or a floor drain that is backing up is a safety issue before it is a plumbing one.
- Note what's affected. One sink points to a local clog; several drains at once usually means the main line.
- Check the lease. Tenants should know whether they or the owner approve repairs.
- Think ahead on expansions. If the job involves new fixtures or an addition, ask about sewer capacity early. A state moratorium on new sewer connections was imposed in 2022, and the plant remains under an amended Special Order by Consent through September 2027.
Symptoms and likely causes
| What you notice | Likely cause |
|---|---|
| Rusty water from one part of the building | Aging galvanized pipe inside that section |
| Floor drains backing up in a kitchen or prep area | Grease and solids in the building drain |
| Weak flow at faucets on an older floor | Corroded supply pipe narrowing the opening |
| Hot water running out early | Sediment, a failing element or an undersized heater |
| Restroom toilets running between uses | Worn flush valves or flappers |
Cost factors
- The age and material of the pipe, since old galvanized and cast iron often need transition fittings
- How many tenants or fixtures are on the affected line
- Working before or after business hours
- Diagnostic time with a camera or leak locator
- Chatham County permit and inspection steps for heaters, fixtures and line work
Siler City's reservoirs are sensitive to drought. Dry spells have brought voluntary water-use restrictions before, so businesses that use a lot of water should watch for TriRiver alerts.
