The project consists of an integrated conveyance system from Highway 169 and 101st Avenue in Brooklyn Park on the west to the Coon Rapids Interceptor (CRI) on the east. The conveyance system will provide capacity relief for the Champlin-Anoka-Brooklyn Park (CAB) and the Elm Creek Interceptor (ECI), in-line storage for relief, and conveyance of flow across the Mississippi River to the CRI. The planned conveyance system will parallel the existing Elm Creek and CAB interceptors, continue east across the Mississippi River to a lift station on the east side of the river, and then end at the CRI. A new gravity interceptor will bring flow from Coon Rapids Lift Station 34 to the proposed lift station. Lift station 34 will be abandoned.

Septage Management - During 2004, MCES completed a study to evaluate the effectiveness of this system and the impact that hauled liquid wastes has on the treatment system to determine the most efficient and cost effective method for treatment and disposal. The recommended plan provided for increased disposal site security, methods to record and monitor loads received, and minimization of adverse infrastructure impacts related to hauled liquid wastes (corrosion, sediment buildup and odors). Several changes to the Hauled Liquid Waste Management Program have been implemented to improve the control of discharges to the MDS, protect the infrastructure, improve security, and capture appropriate revenue costs. Under this project, the current septage site in Chanhassen is being upgraded to meet program requirements. Facilities are currently being designed for the Blue Lake Plant utilizing the prototype facility constructed at the Empire disposal site. In 2009, the septage facility the MCES purchased in Fridley replaced four septage sites in the north metro area.
