Siler City's water system has been absorbed into TriRiver Water, and a leak on the buried pipe from the meter to your house is generally a job for a plumber you hire, though no published source we found states the exact dividing point. Roughly half the town's homes predate 1980, so older lines are common. Call the number on this page to be connected with a local plumber in Siler City.
Older homes, a new utility name
Siler City voted in October 2024 to join TriRiver Water, the City of Sanford's regional utility, and the town's water and sewer assets moved over in 2025. Water still comes from the Siler City filtration plant, fed by the Rocky River Reservoir and the Charles L. Turner Reservoir the town built in 2009. Housing is older than in much of Chatham County: the median home dates to 1980, about half predate it, and the 1950s were a big building decade. Around the downtown and the East Raleigh Street and North Third Avenue historic districts, many service lines have been underground for generations.
What to do right now
- Close the main valve at the house if water is gushing or the yard is flooding.
- Check the meter. With every tap off, watch whether the dial or leak indicator keeps moving.
- Find the wet spot. Note where water surfaces between the meter and the foundation.
- Call TriRiver if the water is at the meter box or near the street.
- Call a plumber if the leak is on your side of the meter.
- Save some water in jugs if the house will be off for a while.
Symptoms and likely causes
| What you notice | Likely cause |
|---|---|
| Muddy patch along the path from the meter to the house | Crack or failed joint in the buried line |
| Every fixture lost pressure at once | Water escaping before it reaches the house |
| Rusty water from the cold taps in a 1950s home | Corroding galvanized pipe |
| Meter moving with all water off | Underground or hidden leak somewhere past the meter |
| Water near the foundation after a freeze | Split where the line rises into the crawl space |
What affects the cost
- Pipe condition. Old galvanized lines often need full replacement rather than a patch.
- Length and depth. Longer runs on bigger lots take more digging.
- Surface. Concrete walks, drives and tree roots slow excavation.
- Method. A short splice, an open trench and a bored new line each price differently.
- Permit. Chatham County Central Permitting & Inspections handles building and plumbing inspections for the Town of Siler City.
Outside town, it depends on the address. Some homes in areas like Silk Hope run on private wells, where the whole line from well to house is the owner's.
