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 Contract No. 2301186/REQ-0000015, “Lake Huron Water Treatment Plant Sludge Removal & Disposal” with M.L. Chartier, Inc., at a cost not to exceed $2,261,200.00 for a duration of 1,460 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote. 

BACKGROUND

The Lake Huron Water Treatment Plant (LHWTP) operates with a maximum treatment capacity of 400 MGD (million gallons per day). During the water treatment process, alum sludge is accumulated in the plant’s sedimentation basins and captured in the filtration process. Filters are regularly backwashed to the on-site residuals system and LHWTP personnel periodically move sludge from the sedimentation basins to the ten on-site lagoons. The residuals facility and lagoons operate together to separate sludge from water and dry the sludge. This allows LHWTP to return clean water to Lake Huron in compliance with its National Pollutant Discharge Elimination System (NPDES) permit.

JUSTIFICATION

Contract No. 2301186/REQ-0000015 will provide final drying and removal of sludge currently existing in the on-site lagoons. Sludge removal will restore the LHWTP’s lagoon capacity, which provides efficient and cost-effective residuals handling. Proper management of the lagoons ensures high quality treated water and is critical to LHWTP’s compliance with their NPDES permit.

FINANCIAL PLAN IMPACT
