Lorton’s sewer lines go back further than people expect: county records date the split foyers and ramblers of Pohick Estates, on LaGrange Street, Sylvania Street and DeVries Drive, from 1957 to 1972, and most of the one-story houses on Wiley Drive and Anzio Lane to 1949. Lines from those years are usually cast iron or clay, and some yards got Orangeburg, wood fiber pipe soaked in tar that slowly flattens under the soil. The camera tells you which.
The townhouse rows came next: Southgate Woods and Williamsburg Square in the early 1970s, Terrace Towne Homes of Gunston on Hagel Circle from 1973 to 1977, then Summerhill, Pohick Village and Washington Square through the 80s. Builders were switching the pipe to the street from cast iron to plastic in those years, so a 1975 townhouse could have either, or both, joined under the front walk.
Laurel Hill and its neighbors came after 2000: Lorton Town Center, Laurel Hill itself, Lorton Station South and Laurel Highlands between 2000 and 2012, and the county’s Laurel Hill Adaptive Reuse area and Liberty Townhomes from 2017 to 2021. That’s PVC all the way, and the trench under it can settle into a belly that holds water. A line no camera has seen has never been checked for one.
About 1 Lorton house in 10 drains to a septic tank, by the county’s records, including every house in Hallowing Point River Estates along River Drive. There our camera runs from the house to the tank’s inlet and stops; the tank and the field are a septic contractor’s. Fairfax County’s septic rules call for cleanouts up at the ground every 50 to 60 feet along that pipe, and where yours has them, that’s how the camera goes in. Septic lots get more room on our Lorton plumbing page.
