Inside town limits, the Town of Herndon runs the water system, buying finished water from Fairfax Water, while Herndon-addressed homes outside the town may be on Fairfax Water directly. When the private line to your house leaks, a plumber can repair or replace it. Call the number on this page to be connected with a local plumber in Herndon.
Herndon's setup
The Town of Herndon's Department of Public Works maintains water and sanitary sewer systems inside town limits and bills for both. Its water comes from Fairfax Water, primarily the Corbalis plant on the Potomac River. Herndon mailing addresses also cover unincorporated Fairfax County areas outside the town, such as south of the Dulles Toll Road, so check your bill: a Town bill means the Town's system, while a Fairfax Water bill means Fairfax Water.
The Town keeps a service line inventory that classifies lines as non-lead, galvanized, galvanized requiring replacement or unknown, and reports that no lead service lines have been found. With a median home built in 1983, many lines are copper of that era, but the galvanized categories are a reminder that some older properties near the historic downtown deserve a closer look. For a leak at the meter in town, Public Works' Operations Division is 703-435-6860.
Inside town limits, Plumbing/Gas permits come from the Town's Building Inspections office; outside the town, Fairfax County Land Development Services handles them.
Weighing your options
| Situation | Fix the section | Replace the line |
|---|---|---|
| Inventory shows non-lead, one leak | Usually right | Not needed yet |
| Inventory shows galvanized | Temporary at best | Plan for it |
| Damage from digging or a fence post | Good fit | Only if damage is long |
| Weak pressure everywhere | Rarely helps | Often the fix |
Signs of a leaking line
- Wet or greener grass along the path to the house
- A meter that keeps registering with everything off
- Low pressure in every room
- Moisture where the pipe enters the basement or crawlspace
Timing
Freezing weather is the most common trigger for sudden breaks, and a split near the foundation can flood quickly, so learn where your main shutoff is before winter. Slow leaks in the yard can usually wait for a scheduled visit, though they still waste water and soften the ground over time. Plumber Washington DC Pros is a referral line, not a plumbing company; your call is connected with an independent local plumber who serves Herndon. Tell the plumber whether you're inside town limits, where the wet spot is and whether the meter moves with everything closed, and they can plan the visit around that.
