This mini-grant project installed a dry well to collect stormwater from the roof of St. Matthew Lutheran Church in Columbia Heights. Previously, stormwater runoff from the roof had spilled directly out into the street; the new dry well infiltration system reduces flooding and allows the runoff to infiltrate into the ground, greatly reducing the amount that eventually reaches the Mississippi River.
A pipe runs from the roof underground to the dry well, a hole filled with drain rock and wrapped in a geotextile. The dry well captures and treats stormwater that runs off approximately 5,000 square feet of the roof. This system is designed to capture and treat a one-inch rain event (240 cubic feet of water).
