Title
Resolution to Approve a Contract with Lee Contracting, Inc. DBA Midwest Power Systems Inc. for the Repair of Four Clarifiers at the Water Resource Recovery Facility (RFP# 26-28) ($181,430.00)
Memorandum
Attached for your review and consideration is a resolution to approve a General Services Agreement with Lee Contracting, Inc. DBA Midwest Power Systems Inc. (MPS), for the repair of four clarifiers at the Water Resource recovery facility (WRRF) in the amount of $181,430.00.
The WRRF operates twelve Ovivo clarifiers, with each treatment train supported by a primary and secondary unit. The clarifiers were inspected in March of 2026, prompted by damage from harsh winter conditions and normal operational wear. Staff with the assistance of an Ovivo technician, identified necessary repairs to clarifier mechanisms on four separate clarifiers at the WRRF. The required work includes repairing and realigning the upper skimmer arms on two primary clarifiers and one secondary clarifier, as well as repairing the lower rake arm on an additional secondary clarifier.
Proper operation of primary and secondary clarifiers are essential in maintaining treatment capacity on an active train. Clarifiers play a critical role in the wastewater process by allowing settleable solids to sink and for scum to rise, which ensures that the highest-quality effluent is discharged. The upper skimmer arm removes floating scum, while the lower rake arm collects settled sludge from the tank bottom. To function effectively, these mechanisms must remain properly aligned and balanced. The identified repairs are necessary to restore optimal performance and to maintain the WRRF's full capacity and compliance with the City's NPDES permit.
