Wixom approves $172,000 engineering design for UV-disinfection upgrades at treatment plant
Summary
Council approved a proposal from Hubbell, Roth & Clark for engineering design work not to exceed $172,000 for ultraviolet disinfection replacement and lift-station control upgrades at the city’s Water Resource Recovery Facility; staff said the full construction package is budgeted at about $2 million and would be bid competitively in 2027.
At the March 25, 2025 meeting, the Wixom City Council approved a proposal from engineering firm Hubbell, Roth & Clark (HRC) for engineering design of ultraviolet (UV) disinfection replacement and lift-station control upgrades at the Water Resource Recovery Facility at a cost not to exceed $172,000 to be charged to the city’s capital reserve.
City staff described the work as design-phase engineering to modernize the treatment plant’s UV disinfection channels and bring lift-station variable-frequency drives (VFDs) and controls into the city’s SCADA system. “The systems are about 18 years old,” said Mister Sickma, a city staff member. He told the council the newer UV technology can produce longer bulb life and reduce maintenance; staff estimated bulb replacement cycles could average about 18 months to two years with current lamps, with new systems offering longer service intervals.
Staff said the design contract is the first step for a larger construction project, and they plan to competitively bid construction. The presenter said staff plans to issue bids in March and start construction in late April to early May during a dry season window; council discussion clarified staff expects construction work to occur in 2027 and staff intends to budget approximately $2,000,000 for the full project in the next capital planning cycle.
Council members asked about budget timing and whether the capital reserve covered the cost without an amendment to the annual budget. Mister Sickma said the engineering fee was included in capital-reserve planning and that staff will refine estimates and shift other line items as needed in future budget work. He also said staff has been doing systematic maintenance and that there is no immediate operational emergency preventing a short-term timeline to complete design and then construction.
The motion to accept Hubbell, Roth & Clark’s proposal not to exceed $172,000 passed by voice vote. The transcript shows the motion carried; no roll-call vote tally appears in the meeting record.
