In a Vienna home, a burst pipe or backed-up drain means closing the main water valve first, and a gas smell means getting outside before calling 911 and Washington Gas. Then call the number on this page to be connected with a local plumber in Vienna.

Am I on Town of Vienna water or Fairfax Water?
It depends on the address. The Town of Vienna runs its own water distribution system, buying treated water from Fairfax Water, and about a third of its roughly 9,300 connections are outside the town boundary. Other parts of the Vienna ZIP codes are on Fairfax Water directly. Sewer is similar: the town serves its own sewer service area, and Vienna-addressed homes outside it are on Fairfax County sewer. The town publishes service area maps, and your bill settles it.
For Town of Vienna customers, Water and Sewer customer service is 703-255-6385. After business hours, the town directs callers to Vienna's non-emergency police line, 703-255-6366, to report a main break or sewer problem.
Are older Vienna homes more likely to have emergencies?
They can be. The median home in Vienna was built around 1971, older than most of the surrounding area, so original valves, drain lines and fixtures are common. The town found no lead or galvanized service lines in its inventory, and nearly all are copper, so the service line itself is rarely the trouble. The common late-night calls are:
- A split pipe in an exterior wall or crawlspace after a hard freeze
- A water heater tank leaking from the bottom
- A sewer lateral clogged by roots, sending water up a basement drain
- An old shutoff valve that won't close when you need it
Water here is moderately hard to hard, about 5 to 10 grains per gallon, which adds scale to tank heaters over time.
What if I smell gas?
Leave the house right away without switching lights or appliances on or off. From outside, call 911 and Washington Gas at 844-WASHGAS (844-927-4427), option 1. Once the utility has secured the leak, a plumber can repair the house piping or reconnect an appliance.
A permit note
Water heater and gas appliance permits go through Fairfax County's PLUS system, and projects inside town limits also need separate Town of Vienna approval uploaded to the same record. A like-for-like gas water heater swap uses a Household Appliance permit. Night and weekend calls usually cost more, and no arrival time is promised; a landmark like Route 123 through downtown or the W&OD Trail helps the plumber find you.
