Council backs pilot study to increase water-plant capacity, approves elevator repair
Summary
Council approved contract work and oversight for a water-plant filtration pilot and authorized an elevator repair; staff said a successful pilot could add about 14 million gallons per day of rated capacity and defer a projected $235 million expansion.
The City of Wyoming authorized two items for the drinking water plant: an elevator repair contract and staff oversight to proceed with a Fishbeck pilot study to evaluate rerating of filtration units.
Council approved a maintenance contract with Coney to repair an elevator at the drinking water plant for just over $16,000 after staff said one of five elevators was not operating properly. Separately, the council accepted Fishbeck’s proposal to conduct a pilot study, which staff described as an EGLE‑approved test of increasing the rated throughput of 12 filters (originally built in the 1960s and 1970s) to raise plant capacity.
Staff said preliminary engineering indicates the pilot could increase rated capacity by about 14 million gallons per day; under current demand projections the city has a planned plant expansion in 2037 estimated at roughly $235 million. If the pilot succeeds and EGLE allows a higher rated capacity, staff said the city could defer that expansion by several years and avoid or delay substantial capital expense.
Councilors asked technical questions about the number and function of elevators, the plan for redesigning older filters to match newer units, and the twofold purpose of the pilot: (1) to test rerating on newer filters and (2) to inform redesign/rehabilitation of the older units. Staff said the pilot has two aims: increase throughput on newer filters and use those design parameters to redesign the oldest filters so all 18 filters eventually have the same design and capacity.
What happens next: Fishbeck will proceed with the pilot oversight as approved and report results to staff; any change to rated capacity requires EGLE approval and subsequent design/rehab work. The elevator repair will proceed per the approved contract.
