In the Papillion Creek South basin along 40th, 41st, 42nd and Q Streets
This project is located in the Papillion Creek South Basin and provides sewer separation to the area bounded by Orchard Avenue on the north, 39th Street on the east, R Street on the south and 44th Street on the west. This project includes construction of both new sanitary sewer and storm sewer. New storm sewers were constructed along 42nd Street, Q Street and R Street. Sanitary sewer were constructed to carry newly separated sanitary sewer flow into an existing combined sewer that was converted to a sanitary sewer. This project was coordinated with the design and construction of a City transportation project to replace a railroad bridge and provide intersection improvements.
As part of the sewer separation design, new green infrastructure was constructed in the eastern portion of Hitchcock Park. New detention basins receive stormwater from new inlets on 42nd Street, will detain flows and allow for infiltration, before directing the remaining stormwater flows back into the new separate storm system at a reduced flow rate and volume. This green infrastructure project achieved Substantial Completion in September 2017. Sewer separation is anticipated to be completed by mid 2019.
