Springfield is unincorporated Fairfax County, so Fairfax Water serves most homes, Fairfax County's Wastewater Management program runs the public sewers, Fairfax County Land Development Services issues permits, and Washington Gas supplies gas. Plumber Washington DC Pros is a free referral line and not a plumbing company. Call the number on this page to be connected with a local plumber in Springfield.

Plumbing services in Springfield
Built out around the Mixing Bowl
Springfield grew from about 1,000 residents in 1950 to more than 25,000 by 1970, and that building boom still shapes the place. The census-designated place counted 31,339 people in 2020, but the four Springfield ZIP codes, 22150 through 22153, held 108,621 and take in North Springfield, West Springfield and Newington Forest. It sits about 12 miles from downtown Washington around the Springfield Interchange, where I-95, I-395 and I-495 meet. Old Keene Mill and Franconia roads, Backlick Road and the Franconia-Springfield Parkway carry local traffic, and Springfield Town Center and the Franconia-Springfield Metro and VRE station anchor the commercial core.
Postwar houses, aging pipe
The median Springfield home was built around 1974, and large parts of the housing date from the postwar and 1960s-70s boom. In houses that age, owners often run into original water heaters long since replaced but original supply piping still in place, corroded shutoffs and cast iron or clay drain lines that roots and grease have narrowed. Basements bring sump pump and floor drain work, and cold snaps freeze lines in exterior walls.
Water service
Fairfax Water serves most populated parts of Fairfax County; confirm by address if you're unsure. It treats Potomac River water at its Corbalis plant and Occoquan Reservoir water at its Griffith plant, and some customers get Potomac water treated by the Washington Aqueduct. It uses chloramines from about July through March and free chlorine from about April through June. Its analyses show moderately hard water, averaging about 7.5 grains per gallon at Corbalis. Owners can check and report their service line material through Lead Free Fairfax. Customer service is 703-698-5800; after-hours water emergencies, 703-698-5613.
Sewer laterals and backups
Fairfax County runs the public collection system. Maintaining the private lateral, from the building to the county sewer and including the connection, is the property owner's job. For an overflow or backup, call the county's 24-hour line at 703-323-1211 to check the main; if the main is flowing, a plumber can camera and clear the lateral.
Permits and backflow
Unincorporated Springfield is permitted by Fairfax County Land Development Services (703-222-0801, online through PLUS). LDS requires permits for new, repaired or relocated plumbing or gas fixtures, including water heaters, with an exemption for like-for-like replacement in the same spot; ask LDS how that applies to your water heater swap. Underground lawn irrigation systems on Fairfax Water need backflow assemblies tested at installation and every year after, and again when repaired or replaced; Fairfax Water's cross-connection staff answer at 571-722-7653.
Gas and the DC comparison
Springfield falls under Fairfax County's Washington Gas default. If you smell gas, leave the house first, then call 911 and Washington Gas at 844-WASHGAS (844-927-4427), option 1. Unlike the District, where DC Water and the DC Department of Buildings handle utilities and permits, Springfield works with Fairfax Water and county offices. Call with your neighborhood and the problem, and you will be connected with an independent plumber who sets price and timing with you.
