Downspout Drainage for Washington Homes
A single roof can shed a surprising amount of water in a Washington thunderstorm, and most of it leaves through just a few downspouts. When those downspouts dump next to the foundation or into a sunken areaway, water finds its way into basements and undermines walks and patios. Downspout drainage routes that water through solid pipe underground to a safe outlet, a dry well, a rain garden or a rain barrel instead.
Local pros check each downspout, its flow during storms and the path to a workable outlet. Solid pipe is buried with steady fall, with a cleanout near the house so leaves and debris can be flushed. On tight rowhouse lots, the outlet might be a small dry well, a planted basin or a pop-up emitter in the yard. Pros keep discharge off sidewalks and away from neighbors, and they call 811 a few days before digging.
English basement areaways in Logan Circle, Shaw and Capitol Hill often flood because a downspout dumps right above them. Detached homes in Brookland and Chevy Chase DC benefit from routing several downspouts to one buried line that ends well away from the house. RiverSmart Homes may help with rain barrels; check the rules.
