Inside town limits, the Town of Herndon's Public Works department maintains the sanitary sewer; Herndon-addressed homes outside the town are generally on Fairfax County sewer. Either way, the line from your house to the public sewer is private, and a sewer camera inspection films it to find roots, cracks, sags or buildup. Call the number on this page to be connected with a local plumber in Herndon.
Local conditions in Herndon
Herndon is an incorporated town in the Dulles Technology Corridor, with a historic downtown along Elden Street and the W&OD Trail and Silver Line Metro access. The median home was built in 1983. Many laterals are plastic, where the camera usually finds sags, separated joints or damage from later digging, while older houses near the historic district can have clay or cast iron with roots and scale.
The Town runs its own water and sewer utility for properties inside town limits, and water and sewer are billed by the Town. Herndon mailing addresses also cover unincorporated Fairfax County areas outside the town, such as south of the Dulles Toll Road; those homes are generally on Fairfax County sewer, where the County's 24-hour line is 703-323-1211. The Town's Operations Division can be reached at 703-435-6860.
Permits follow the same split. Inside town limits, the Town of Herndon Building Inspections office issues Plumbing/Gas trade permits; outside, Fairfax County Land Development Services does.
Inspection options compared
| Option | Best for | Keep in mind |
|---|---|---|
| Camera from an outside cleanout | Most single-family homes | Line may need clearing first |
| Camera through a toilet flange | Homes with no usable cleanout | Toilet must be pulled and reset |
| Jetting followed by camera | Grease or heavy root buildup | Gives the clearest view of the pipe wall |
| Camera after a repair | Confirming new pipe or a liner | Useful record for a future sale |
Signs it's time
- Low drains backing up when upstairs fixtures run
- Gurgling toilets and slow tubs at the same time
- A sewage smell near the cleanout or in the basement
- Repeated clogs after cleaning
Timing notes
Roots grow fastest in the warm months, so a line that slows through spring and summer is a likely candidate. Heavy summer storms can also push groundwater into cracked joints. If sewage is coming up, stop using water and get help; the camera goes in after flow is restored. For slow drains, a weekday inspection is less disruptive than waiting for a full backup. When you call, you are connected with an independent plumber who works in Herndon; mention whether you are a Town or County sewer customer and which fixtures are affected.
