Sewer Installation in Fairfax

New Sewer Lines, Connections, Repairs & Replacements

Sewer line installation can mean adding a line where none exists or connecting a home to an available public sanitary sewer. It differs from sewer repair, which addresses specific damage, and sewer replacement, which renews an existing line.

A site evaluation helps determine which solution fits the property and its plumbing. Existing damage, the proposed route, and underground obstacles can influence whether the project requires a new connection, repair, replacement, or another approach.

Trenchless sewer work uses methods intended to limit surface excavation. Whether it is suitable depends on the property, line route, and underground conditions, so the approach should be determined only after an evaluation.

Fairfax County Public Sewer Connection Requirements

Fairfax County maintains separate systems for sanitary sewage and stormwater. A residential wastewater line must connect to the sanitary system, not a stormwater sewer.

A permit is required to connect a building to available county sewer service. For a single-family home, the sewer main must be within 300 feet of the building for service to be considered available under the county requirement. A licensed plumber must obtain the connection permit.

Project planning must also identify the applicable connection point and distinguish private property piping from public infrastructure. Responsibility can vary between these portions of the system, so the boundaries should be established for the specific property rather than assumed.
