Gilmore Avenue Sewer Separation Phase 1 and 2 Project


Currently under construction.

Project Description

The improvements under construction will provide sewer separation to an approximately 226-acre area in the Ohern/Monroe Basin and conveyance of creek flows to the Ohern/Monroe South Barrel for conveyance to the Missouri River. The project consists of abandonment of some existing pipes, rehabilitation, and construction of new storm and sanitary sewers. The newly constructed and rehabilitated sewers will convey stormwater flow to the Ohern/Monroe South Barrel and sanitary flows to the Ohern/Monroe North Barrel. The project also incorporates green infrastructure with a detention basin at Harrison Street that decreases the size of downstream storm sewers and offers benefits to neighborhood residents. Green Infrastructure is also incorporated in Albright Park, and facilitates the construction of two new soccer fields for the neighborhood.

The Ohern/Monroe North and South Barrels are large box culverts that convey combined sewer flows to the Missouri River Water Resource Recovery Facility (MRWRRF) with overflows to the Missouri River. A future project will result in a separation of combined flows to the north barrel and stormwater only to the south barrel.

The project also includes the abandonment of an existing City of Bellevue pump station. This will eliminate operation and maintenance costs for this facility, which was in need of extensive improvements to keep the facility in operation. The City of Bellevue is paying for the abandonment of this pump station.
