Prince William Water provides sewer service in Dumfries, and the line from your house to the public sewer is private plumbing that a plumber repairs. Permits and inspections for that work, including sanitary sewer, go through the Town of Dumfries rather than the County. Call the number on this page to be connected with a local plumber in Dumfries.

What happens when you call
You'll be connected with an independent plumber who works in Dumfries. Expect questions about which fixtures are affected, whether water has come up through a tub or floor drain, and how often the line has needed clearing. The visit usually starts with opening the line so the house can drain, then a camera inspection to find out why it clogged. The camera spots roots, cracked or offset joints, sags and debris, and a locator marks the spot from the surface. You'll hear the repair options before anything beyond clearing is done.
Cost factors
- How deep the line is and how far the problem sits from the house
- Pipe material and how much of it is damaged
- Whether a liner fits or a section must be dug out and replaced
- Surfaces over the line, from lawn to concrete
- Permit and inspection through the Town of Dumfries
Dumfries conditions
Dumfries is a small historic town on U.S. 1 near Quantico Creek, chartered in 1749 and described as the oldest continuously chartered town in Virginia. Today it's a commuter town just east of I-95 in eastern Prince William County, about 29 miles from Washington. Housing ranges from older homes near Main Street to newer subdivisions, so laterals can be anything from clay or cast iron to plastic; a camera inspection is the way to know what's under your yard.
Prince William Water supplies Dumfries households and provides sewer service. Its Emergency Dispatch line, 703-335-7990, handles after-hours problems, and Customer Service is 703-335-7950 on weekdays. Permits work differently here than in the surrounding county: the Town of Dumfries Building and Inspection Department handles building and trade permits and inspections, including plumbing and sanitary sewer, and Prince William County's Building Development Division does not issue permits inside the town. Town Hall is at 17739 Main Street, 703-221-3400.
Checklist before the plumber arrives
- Stop running water and hold off on flushing
- Find the cleanout and clear access to it
- Confirm whether your address is inside town limits
- Write down when it started and which drains are affected
If you live just outside town limits, your permit goes to Prince William County instead, so mention your exact location when you call.
