Omaha CSO

In the Nicholas Street Phase 1 (10th Street to 16th Street) Project, storm and sanitary sewers were extended to provide additional sewer capacity north and west of the Omaha's Convention Center and Arena, north of Nicholas Street, and to provide sewer separation for the area north from Nicholas Street on 11th Street to Clark Street. Three (3), nine-foot diameter storm sewers and one (1), 24-inch diameter sanitary sewer were extended west from Abbott Drive at approximately 10th Street to 16th Street, following an alignment approximately one-half-block north of Nicholas Street. Both storm and sanitary sewers along 11th Street between Clark and Nicholas Streets were replaced in order to provide separation to this area. As part of the project, the abandoned four-story Economy Products building near 11th and Nicholas Street was demolished and 11th Street was repaved.

Additional phases of the Nicholas Street Extension extend the sanitary and storm sewers into the neighborhoods to the north and west at 16th Street to provide for additional sewer separation.
