Grosse Ile wastewater upgrades move forward; commission recommends purchase and engineers approve work
Summary
The Public Services Commission recommended awarding a contract for a replacement filtration system at the wastewater plant and received updates on odor control, sludge hauling, lift-station equipment and lead-service-line work.
GROSSE ILE, Mich. — Township staff reported progress this month on multiple wastewater-treatment projects and the Public Services Commission recommended the board approve a contractor to replace a failing filter at the wastewater plant.
Ryan, manager of the wastewater plant, told the commission, "Sludge hauling was finished in late March. It went well. No issues with that." He also reported the odor-control system installed in the plant's primary room in early April is operating and appearing to mask odors; staff will monitor resident complaints into early summer.
On a purchasing action, the commission recommended that the township board award an installation contract to Monroe Plumbing and Heating for the replacement of a self-cleaning filtration system. Derek said Monroe was the low bidder at $92,000 and staff recommended adding a 10% contingency for a total authorization of $101,200; the recommendation will go to the board for final approval.
Ryan also reported that the level-1 sludge transfer pump and line installation completed in late April and that lift-station electrical work for four of five lift stations had an engineer's estimate of roughly $68,000; staff asked the commission to authorize procurement but agreed the purchase could wait until the June meeting.
Staff updated the commission on compliance work. Derek reported that the township submitted the required administrative documents to EGLE and the EPA reimbursement process was underway for a recently completed HVAC project. "We've already been reimbursed about $550,000 on the $700,000 project," he said, noting the final invoice remained pending. He also said the performance project certification (PPC) for the administrative consent order requires additional information requested by EGLE and staff and engineers are preparing the revisions.
On lead service lines, staff said the township completed a lead service-line inventory as required by the state and budgeted approximately $70,000 this year for lead-line replacement work; the program will follow the state-mandated replacement schedule and sampling program beginning in June.
The commission did not approve a final purchase order for the lift-station work at the meeting; commissioners and staff agreed the procurement could be finalized in June. The installation of the new filter and other plant upgrades are budgeted items; if the board approves the commission's recommendation, work would proceed through the township's normal contracting and reimbursement process.
