Lorton homes on Fairfax Water own the service line after the meter, so a leak in the buried pipe to the house is a plumbing repair. A plumber can trace the leak and repair the section or replace the line. Call the number on this page to be connected with a local plumber in Lorton.

Lorton at a glance
Lorton is an unincorporated part of southern Fairfax County along I-95 and Route 1, between Fort Belvoir and the Occoquan River. Fairfax Water's Griffith Water Treatment Plant, which treats Occoquan Reservoir water, is nearby, at the southern tip of its service area. The housing is mostly newer: only about 17% of homes in ZIP 22079 predate 1980, and the 2000s were the biggest building decade, including the Laurel Hill area around the former reformatory site. Newer lines generally fail at joints or from digging damage rather than age.
What to do now
- Stop the water. Close the main shutoff if water is entering the house.
- Rule out irrigation. Turn the sprinkler system off and see whether the wet area stays.
- Watch the meter. With every fixture off, check whether the leak indicator moves.
- Decide who to call. A leak at the meter or in the street goes to Fairfax Water: 703-698-5800, or 703-698-5613 after hours. A leak past the meter is yours.
- Check your HOA rules. Many Lorton communities have rules on digging and restoring front yards.
- Report your pipe. Fairfax Water's Lead Free Fairfax survey and online inventory track service line material on the customer side.
Signs and causes
| Symptom | Likely cause |
|---|---|
| Soft lawn near the curb or driveway edge | Leak near the meter end of the line |

| Pressure falls off when two fixtures run | Restriction or partial break in the line |

Cost factors
- Run length, which differs between townhouse rows and larger lots near Mason Neck
- Whether one joint failed or the whole line should be replaced
- Driveways, walks and landscaping that need restoring
- Sloped or wooded ground that slows digging
- Permits from Fairfax County Land Development Services, filed through PLUS
