The Nicholas Street Sewer Extention Phase 3 Project includes further extension of the storm trunk sewer from the Phase 2 junction structure at 16th & Charles to the north and west to serve additional areas in the Burt-Izard Basin. The project has been broken up into two separate projects — Phases 3A and 3B.
This project will reduce the combined flows downstream of the project area and thereby reduce combined sewer overflows to the Missouri River. In addition, full pavement removal throughout the extent of the project will take place. Along 16th Street, the street pavement will be narrowed and provide bike lanes and parking. Restoration will include sidewalk replacement and ADA compliant ramps.
PICTURED ABOVE: The Long Term Control Plan (LTCP) for the CSO Program includes a variety of CSO control projects, ranging from sewer separation to high-rate treatment facilities as well as green infrastructure projects, all implemented under the oversight of the City and Program Management Team.
The Nicholas Street Sewer Extension Project is being constructed in two phases, Phases 3A and 3B. Phase 3B construction will take place in years 2021 through 2024. Metropolitan Utilities District will be replacing a large gas pipeline on the east side of the 16th Street corridor prior to Phase 3B construction. Other utilities will be relocating their respective utilities in the 2020 and 2021 time period.
Phase 3B construction contract was awarded in May 2021, with construction expected to begin in September 2021.
