MOTION
Upon recommendation of Cheryl Porter, Chief Operating Officer - Water and Field Services, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Chief Executive Officer (CEO) to enter into Requisition No. 2400082/REQ-0000330, “Northeast Water Treatment Plant Filter Replacement” with Kokosing Industrial, Inc., at a cost not to exceed $138,989,000.00 for a duration of 1,825 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
This proposed contract is a design-build contract focused on the rehabilitation of the filters at the Northeast Water Treatment Plant. Filter components including underdrains, media, wash water troughs, surface wash water equipment, wash water equipment, and filter controls are original to the late-1950s plant construction. These filter components have exceeded their useful design life, with mechanical components of the filters being inoperable resulting in excessive maintenance required to meet treatment criteria and system demands.
The work includes rehabilitation of the existing filter clay underdrain system, removal and replacement of the existing filter media, wash water troughs, surface wash water equipment, filter control system, wash water system improvements, and miscellaneous architectural and mechanical improvements to the Wash Water Building and Filter Building. Improvements will right size the filtration capacity from 300 million gallons per day (MGD) to 190 MGD. The proposed contract is anticipated to be substantially completed by December 31, 2029.
JUSTIFICATION
Improvements under this proposed contract are necessary to meet the requirements of the agreed upon terms of the Administrative Compliance Agreement (ACA-399-15-2023) between the Great Lakes Water Authority and the State of Michigan.
