Overview
The City of Omaha will replace an existing sanitary sewer force main line from the East Omaha Lift Station to 11th Street with a new line. The new alignment will be along Avenue H in Carter Lake, Iowa, and 11th and 15th Streets in Omaha. The project will include 7 phases, with Phases 1 through 6 being the construction of the new sanitary sewer force main and Phase 7 being the decommissioning and abandonment of the existing force main that runs along Avenue G. The new sewer force main will not be in service until Phases 1 through 6 are completed, and sanitary sewer services will not be affected during construction.
The purpose of the project is to replace an existing pipeline that has a history of failures, including multiple pipeline breaks needing repairs by city staff. These breaks have caused sewer service issues with repairs that are challenging due to the existing location of the pipeline along Avenue G and the corresponding railroad tracks. Upon completion of the project, sewer service reliability will be increased, and any future maintenance will be much simpler and more accessible for staff.
