Marshopolis is a water treatment plant that acts as an event and ecology condenser. Located in the Northern part of the Southend neighborhood of Bridgeport, Connecticut, the site is a vacant lot of 800 x 600 ft which used to be the grounds of the Seaside Village Homes residential complex that was demolished in 2012 after Hurricane Sandy hit the area. It is located right by the Cedar Creek Reach which connects it and the City’s western water treatment plant to the Long Island Sound. The project attempts at complementing the western water treatment plant facilities by offering secondary treatment to the excess water, helping lower the occurrence of sewage overflow which has been plaguing the south end neighborhood of the city for decades.
