Hydro jetting clears a Herndon main drain or sewer lateral by washing it out with high-pressure water, removing grease, scale and roots more completely than a cable. Inside town limits, the Town runs the public sewer; outside, it may be Fairfax County. Call the number on this page to be connected with a local plumber in Herndon.

Herndon sewer and housing
The Town of Herndon runs its own water and sewer utility inside town limits; its Department of Public Works maintains the sanitary sewer system, and the Town bills for both. Herndon mailing addresses also extend into unincorporated Fairfax County, for example south of the Dulles Toll Road, where public sewer is the County's. Your bill shows which applies. For a Town sewer concern, the Town's Operations Division is at 703-435-6860.
The median Herndon home was built around 1983, and the historic downtown has much older buildings. That mix means some homes have plastic drains where grease and wipes cause most clogs, while older ones may have cast iron or clay with scale and root problems. Jetting works on both, with the pressure matched to the pipe.
Snaking versus jetting
| Point | Snaking | Jetting |
|---|---|---|
| Method | Rotating cable cuts through the clog | High-pressure water scours the pipe |
| Grease and scale | Mostly left in place | Washed away |
| Roots | Trimmed in a narrow path | Cut back to the joint and flushed |
| Best use | Single, close-in blockage | Repeat or whole-line buildup |
Signs to look for
- Several drains slow down together
- The basement or lowest drain backs up when other fixtures run
- Sewer odor near the cleanout
- Repeat clogs after cabling
Timing
Roots grow most actively in the warm months, so slow lines often get worse in summer. Cleaning a line with a root history in spring can prevent a backup during heavy storms. If a camera finds damage, plumbing repairs inside town limits need a Plumbing/Gas trade permit from the Town's Building Inspections office; properties outside town go to Fairfax County Land Development Services.
When you call, mention whether the house is inside the Town or in the surrounding county area. It helps the plumber know which office to deal with if a repair turns out to be needed. Also mention how old the house is. A house near the historic downtown and a newer townhouse can have very different pipe materials, and the right nozzle and pressure depend on which one the plumber is facing. If you have records from a past cleaning or a camera inspection, have them handy as well.
