South and Central Segments - Construction completed.
North Segment - Currently under construction. The force main construction will be completed in December 2017. Restoration of Heartland of America Park will be completed by May 2018.
The existing South Interceptor Force Main (SIFM) was constructed in the early 1960s and has remained in continuous operation for more than 50 years. The current condition of the existing SIFM makes it unreliable for continued long term use and replacement is necessary to convey dry and wet weather flows to the Missouri River Water Resource Recovery Facility (MRWRRF). Rehabilitation is not a viable option as the force main does not have a back up and must run continuously. The new SIFM will provide this needed reliability in addition to increased flow capacity.
The new SIFM will consist of approximately 4,360 feet of 48-inch diameter pipe from south of the I-480 Bridge to the new Leavenworth Lift Station and 18,390 feet of 64-inch diameter pipe from the new Leavenworth Lift Station south to the MRWRRF. Various other sewers and structures required to move flow from Leavenworth Street, Hickory Street, and Pierce Street sewers to the Leavenworth Lift Station are also included in the project. Abandonment and/or elimination of the existing SIFM will be evaluated after the new SIFM is placed into service. The SIFM is being constructed in three segments: North, Central and South.
The South and Central Segments are completed. After encountering a geologic anomaly in 2016, a rescue shaft was constructed in second quarter, and tunneling was completed in August 2017.
