Lorton is on Fairfax County's sewer system, and County Code makes the property owner responsible for the private lateral from the house to the County main. A sewer camera inspection records that lateral so you can see whether a sag, offset joint, roots or buildup is behind your trouble. Call the number on this page to be connected with a local plumber in Lorton.

Lorton in brief
Lorton is a southern Fairfax County suburb along I-95 and Route 1 between Fort Belvoir and the Occoquan River, with nearby areas such as Laurel Hill, Newington and Mason Neck. Housing is mostly newer: only about 17% of homes in ZIP 22079 were built before 1980, and the 2000s were the biggest building decade. Fairfax County's Noman M. Cole, Jr. Water Recycling Facility, the County's wastewater treatment plant, is in Lorton.
With mostly plastic laterals, the camera here usually finds settling, joint separation, construction debris or damage from later landscaping rather than corrosion. Older homes in the area can have earlier materials with roots at the joints.
What to do now
- Limit water use so the backup doesn't spread.
- Call the County if sewage is coming up with nothing running. Fairfax County's 24-hour sewer line is 703-323-1211; the County checks its main.
- Check with your HOA if you live in a townhouse community, since some lines are shared.
- Locate the cleanout near the foundation; don't open it while the line is full.
- Have the line filmed from the cleanout to the County connection, with defects marked on the surface.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Water holds in the line after flushing | A belly where backfill settled |
| Clog at the same distance each time | An offset joint or leftover construction debris |
| Problems started after yard work | Pipe damaged by digging, posts or heavy equipment |
| Gradual slowdown in a busy house | Grease and wipes coating the pipe |
| Lowest drain gurgles or backs up | Partial blockage in the building drain or lateral |
Cost factors
- Cleanout access and whether the line must be cleared first
- Run length from the foundation to the main
- Locating, marking and recording the inspection
- Jetting when grease hides the pipe wall
When you call, you are connected with an independent plumber who works in Lorton. Mention the age of the house, whether you live in an HOA community and which fixtures are slow. Fairfax County does not locate or mark private laterals, so the plumber's locator is how the route and any defect get marked. Repairs that replace pipe need a permit from Fairfax County Land Development Services through PLUS.
