RE:                     Contract No.   RFB 1128

                     Hauling and Disposal of Bar Rack Screening and Grit

                     Vendor:  Waste Management of Michigan, Inc.



Upon recommendation of Suzanne Coffey, Chief Planning Officer, Interim Chief Operating Officer -Wastewater, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Chief Executive Officer (CEO) to enter into Contract No. RFB 1128, “Hauling and Disposal of Bar Rack Screening and Grit” with Waste Management of Michigan, Inc., at a cost not to exceed $1,713,000.00 for a duration of two years with two one-year renewal options at $856,500.00 per year; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote. 


When wastewater enters the Water Resource Recovery Facility (WRRF), screenings (rags, sticks and other objects) and grit are removed by preliminary and primary treatment of wastewater. The screenings and grit are transported by conveyors and temporarily staged in waste storage bins while awaiting final disposal to landfill. The services to be provided under this contract consist of furnishing all labor, equipment, containers, transportation and disposal of screenings and grit from Pump Station-I and Pump Station-II at WRRF, and various Combined Sewer Overflow (CSO) treatment facilities to the landfills. The contractor is responsible for the safe transportation and disposal of screenings and grit, estimated to be 15,000 tons per year, into a State approved, licensed landfill.


The NPDES Permit MI0022802 requires GLWA to remove and dispose of the screenings and grit to limit solids discharged into the Detroit River and Rouge River. A vendor is needed to haul and dispose of screenings and grit from WRRF and CSO treatment facilities to various State approved landfills. 


Summary:  The forecast for the disposal of material from the Wastewater Primary Processing for screenings and grit was increased in the Financial Plan. This was due to the decommissioning of Incineration Complex I, which had been a disposal method for grit now covered by this contract. The volume was increased to 15,000 tons at an average rate of $55.37 per ton. The maximum value of the contract exceeds the current financial plan in total. The volume of screening and grit disposed may vary by year which could possibly require an amendment to that years’ financial plan.
