Inside the Town of Haymarket, Prince William Water provides water and sewer, and plumbing permits come from Prince William County after the Town grants zoning approval. Replacing the private sewer lateral is the right call when a camera shows damage beyond a single spot. Call the number on this page to be connected with a local plumber in Haymarket.

Is my Haymarket home on public sewer?
Inside town limits, the Town lists Prince William Water for water and sewer. The Haymarket 20169 postal area also covers large unincorporated areas outside the town, and service there varies by address, so some rural properties may not be on municipal sewer. Check your bill: a Prince William Water sewer charge means you are connected. For outages or main problems, Prince William Water's Emergency Dispatch is at 703-335-7990; customer service is 703-335-7950 on weekdays.
Why would a Haymarket sewer line need replacing?
Haymarket is a small historic crossroads town at the base of the Bull Run Mountains, incorporated in 1882, with a largely unchanged 1880s core surrounded by newer growth along I-66. The median home was built in 1997. Most laterals are plastic, which tends to fail where soil settled under the pipe, where joints separated, or where later construction crushed a section. Homes in the older core may have earlier materials that crack and let roots in. When problems appear at several points along the run, replacing it is usually better value than piecemeal repairs.
What permits are needed in Haymarket?
All building permits for properties in town, including plumbing, are issued by Prince William County Development Services. Before the County permit, applicants get Zoning Approval from the Town of Haymarket (Town Hall, 703-753-2600). Properties outside town limits go straight to the County. The plumber usually handles the filings, but confirm that the Town step is on the schedule so the job is not held up waiting for it.
A local note
Many newer Haymarket neighborhoods have associations with rules on excavation and how lawns and common areas are restored. If the pipe keeps its slope, trenchless replacement from small pits keeps disruption low. Ask for the camera recording, a marked route and a written scope listing the method, the length of new pipe and the restoration included before work begins. Near the historic core, lots are small and close to the road, so walk the route with the plumber and agree on where pits and equipment will go. Keep the inspection record with your property papers.
