Ashburn is unincorporated Loudoun County, so Loudoun Water provides public water and sewer, and Loudoun County Building and Development issues trade permits. Most commercial buildings here are newer, so calls lean toward fixtures, water heaters, drains and annual backflow tests rather than old pipe. Call the number on this page to be connected with a local plumber in Ashburn.
Who supplies water and sewer to a building in Ashburn?
Loudoun Water, which is headquartered in Ashburn, serves the unincorporated parts of the county within its service areas. Its Central System draws mainly on the Potomac River, with Goose Creek and the Beaverdam reservoir used as needed, and treats water at its Trap Rock facility while also buying treated water from Fairfax Water's Corbalis plant. Both sources use chloramine as the disinfectant. Loudoun Water says it has no lead service lines in its system. Customer Relations is 571-291-7880, and after-hours emergencies go to 571-291-7878.
What backflow and permit rules apply?
Loudoun Water's cross-connection program protects the system from non-potable connections such as irrigation and pools, and backflow preventers must be tested every year by a certified tester. Office parks, restaurants and shopping centers with irrigation, fire lines or process equipment should expect that annual cycle. Trade permits for gas, mechanical and plumbing work are applied for as sub-records of a parent building permit, either online through LandMARC or in person at the County office in Leesburg; plan review questions go to 703-777-0220.
Why do newer buildings still need commercial plumbers?
Ashburn grew quickly from former farmland starting in the 1980s, and only about 2% of homes in ZIP 20147 predate 1980. Newer doesn't mean trouble-free. Water heaters and flush valves installed at the same time tend to wear out at the same time, kitchen lines in busy restaurants collect grease no matter their age, and the campuses along Loudoun County Parkway and Route 7 have large restrooms, break rooms and irrigation that need routine service. Lease turnovers in shopping centers also bring fixture changes and tenant build-outs.
A note on gas
Loudoun County is split between Columbia Gas and Washington Gas, with propane where neither serves, so check the bill to see which company supplies your building. If anyone smells gas, get everyone outside first, then call 911 and that gas utility. For propane, call 911 and your propane supplier from a safe distance. A plumber can then check the piping, test for leaks and restore appliances once the utility has made the line safe.
