RE: Contract No. 2202164
Screenings & Grit Transportation and Disposal from WRRF & CSO Facilities
Vendor: Waste Management of Michigan
MOTION
Upon recommendation of Navid Mehram, Chief Operating Officer - Wastewater Operating Services, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Chief Executive Officer (CEO) to enter into Contract No. 2202164, “Screenings & Grit Transportation and Disposal from WRRF & CSO Facilities” with Waste Management of Michigan, at a cost not to exceed $1,998,900.00 for a duration of two (2) years; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
As wastewater enters the Water Resource Recovery Facility (WRRF), the influent pump stations lift the wastewater to an elevation allowing it to flow by gravity through the preliminary and primary treatment processes. The preliminary treatment consists of a bar rack to remove rags, sticks, leaves, etc. They are collectively known as screenings from the wastewater stream. Once the screenings are removed, the inorganic material such as sand will settle in large tanks as grit. The screenings and grit are transported by process equipment and temporarily staged in waste storage bins while awaiting final disposal for the landfill. The scope of work for this contract involves the contractor furnishing all labor, material, supplies, equipment, and disposal sites (landfills) necessary for safe transport and disposal of all screening and grit generated, into a state approved, licensed landfill.
JUSTIFICATION
The GLWA wastewater system captures an estimate of 15,000 tons of screenings and grit a year throughout all its facilities. The National Pollutant Discharge Elimination System (NPDES) Permit MI0022802 requires GLWA to remove and dispose the captured 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 Combined Sewer Overflow (CSO) treatment facilities to various State approved landfills.
FINANCIAL PLAN IMPACT
Summary: There are insufficient funds in the current financial plan should this contract be utilized to the maximum value. The volume of screenings and grit disposed of may vary by year, which could possibly require an amendment to that year’s financial plan. Should an amendment be required, it would first offset other costs that may be reduced, then from other budget areas, and finally from the unallocated reserve.
