There’s no public tally of Aldie basements to quote you. The Census does count the rest: about six in ten homes in 20105 are single-family houses, about three in ten are townhouses, and 93 in 100 were built since 2000. A house that young with a level below grade usually has drain pipe around its footings, carrying groundwater to a pit with a pump in it. A round lid in the lowest floor, a pipe climbing toward an outside wall: that’s yours.
The pump’s age depends on the street. Stone Ridge’s median owner home was built in 2009, so a pump that came with the house would be about seventeen, roughly twice what pump makers expect, and many have been swapped once already. Across 20105 the median is 2013, which leaves plenty of originals at twelve or thirteen.
More than half of Stone Ridge’s homes are townhouses, where the discharge leaves through the back wall into a small yard with neighbors on both sides. The association’s design standards never mention sump pumps. The nearest rule covers downspouts: an extension, buried pipe included, can’t harm an adjacent property, and above ground it can’t reach past four feet from the house. If the old discharge empties toward the next patio, move it while the pump is out, after a word with the association.
Indoors, sump water doesn’t belong in the sewer. Loudoun Water’s rules define the building sewer as a pipe for household sanitary waste, and where the utility serves a house through one of its grinder pump systems, they bar sump pump, roof and foundation drain water from the grinder chamber outright. On the septic lots past the village, a drainfield is sized for the household’s wastewater, not groundwater. We don’t touch wells or septic, but a farmhouse sump pump is the same $697 replacement as one in Stone Ridge.
