Inside the City of Alexandria, the year your sewer lateral went in decides how much of it you own. On a lateral laid before July 1, 1955, the owner’s share runs from the curb to the house; on newer ones the City’s wording runs it further out toward the main, so ask the City where yours stops before anybody digs. About 3 in 10 owner-occupied City homes predate 1960, and in Old Town, where the street sewer dates to the 1800s, the pipe under the front step can be anything from clay to cast iron.
The City runs cameras through its own mains to decide which to rehabilitate, and looks after the City-owned portions of laterals. The private stretch is the owner’s to inspect, and a camera run with a locator is how you learn which side of the curb a break is on. Reconnecting at a City main takes a lateral connection permit from Transportation and Environmental Services.
On the Fairfax County side there’s no date to check: the owner has the whole lateral, out to the county main and under the street, and replacing it takes a county plumbing permit, plus a VDOT permit under a state road. The typical owner’s house in Belle Haven dates from 1957, and in Fort Hunt, nearly all single-family houses, from 1963. Pipe laid then is usually clay or cast iron, and some houses finished from the late 1940s into the early 1970s drain through Orangeburg, a fiber pipe that slowly goes oval under the soil’s weight.
Kingstowne and Franconia are the younger end. About 7 in 10 Kingstowne homes and two thirds of Franconia’s went up between 1980 and 1999, about half of them townhouses, usually on plastic pipe with no clay joints for roots to find. There the camera checks the grade: a stretch that sank with its trench and now sits low.
