The combined sewer overflow of storm water is not properly managed in the 26th Ward. It is the leading cause of water pollution. Currently, an estimated 189 million gallons of raw sewage overflows annually into the Jamaica Bay. Combined Sewer Overflow is storm water that falls on roofs, streets and sidewalks, in addition to wastewater from homes and businesses, is carried through the sewer system to treatment plants. About 50% of land in the 26th Ward is used for residential purposes . The Sewer shed takes up 5,575 acres- smallest sewer shed in Jamaica Bay area which is not large enough to tackle CSO. About 70% of land in 26th Ward area is impervious and 30% pervious. A possible solution to the 26th ward is the implementation for a grey green infrastructure. More specifically, a storage tunnel interception that can contain CSO’s and impervious ground that can slow down infiltration into the system without increasing runoff.
