Omaha CSO

The Forest Lawn Creek Inflow Removal and Outfall Storm Sewer Project is one of a series of projects in the Minne Lusa Basin intended to remove and/or control inflow into the combined sewer system (CSS) and reduce the frequency, magnitude, and duration of CSOs.

This project specifically is intended to remove Forest Lawn Creek flows from the CSS system, which currently enters the CSS through a structure located near 36th and Hanover Streets.

This project will include sewer separation in specific areas to separate the stormwater and sanitary flows in the project area. Stormwater flows from Forest Lawn Creek will be directed to the Missouri River during all rain events providing additional capacity in the local collection system and reducing the potential for back-ups into basements and street flooding. This will also provide a significant reduction in CSOs in this area. Sanitary sewer flows will be directed to the conveyance sewers to the  Missouri River Water Resource Recovery Facility for treatment.
