Upgrade at Gowanus Houses designed to decrease overflow into canal
A drainage upgrade at NYCHA’s Gowanus Houses will improve the health of the entire Gowanus Canal area, the city Department of Environmental Protection, which did the work, said on Monday.
The project, which was completed earlier this year, included the construction of nine green infrastructure installations that DEP says will capture nearly 2 million gallons of stormwater in a typical year.
The green infrastructure that was built at the Gowanus Houses cost approximately $830,000 and includes permeable concrete sidewalks, subsurface infiltration chambers and a rain garden. Each of these infrastructure installations will allow stormwater to be absorbed naturally into the ground, minimize “ponding,” and keep stormwater from entering the sewer system, where it would otherwise contribute to overflows into the Gowanus Canal.
