Chantilly is on Fairfax County's public sewer, and the property owner maintains the private lateral from the building to the County main. A sewer camera inspection films that lateral to show what is blocking or damaging it and where. Call the number on this page to be connected with a local plumber in Chantilly.

What is the sewer line under a Chantilly house usually made of?
Chantilly is an outer Northern Virginia suburb about 25 miles west of Washington, centered on the Route 50 and Route 28 interchange, with neighborhoods such as Franklin Farm and Greenbriar. The median home was built in 1987, so most laterals are plastic. Older homes in Greenbriar and nearby areas can have earlier materials, and the camera makes the difference obvious on screen. Plastic does not rust, so the usual problems are physical: a low spot where the trench settled, a joint that pulled apart, roots working into a loose fitting, or a pipe damaged during later work on decks, fences and patios.
Fairfax County won't mark my lateral. How do I find where it runs?
That is one of the most practical reasons to use a camera here. Fairfax County owns the public sewer mains but does not locate or mark private laterals. A sewer camera usually carries a small transmitter near its head, and the plumber follows it from the surface with a handheld locator. That lets them mark the path of the line and the spot of any defect, along with an approximate depth, before anyone decides whether to dig.
Should I call the County or a plumber first?
If sewage backs up with no fixtures in use, Fairfax County says to call its 24-hour line at 703-323-1211 first so the County can check its main. If the main is flowing, the blockage is in your private lateral and it is the owner's job to fix. Slow drains without a backup can go straight to a plumber. A camera inspection then shows whether the line needs cleaning, a spot repair or a longer section of new pipe.
A short local note
When you call, you are connected with an independent plumber who works in Chantilly. Mention the age of the house, which fixtures are slow and whether you have contacted the County. Filming needs no permit; if pipe has to be replaced, Fairfax County Land Development Services issues the permit through PLUS, and the plumber doing the repair normally handles it. Townhouse owners should check with their association first, since some lines run through shared ground. Ask for a copy of the video so you can compare any repair quotes against what the camera actually showed.
