Title
Resolution to Approve a Sole Source Purchase Order to Hach Company for Turbidimeters and Controllers ($79,776.00)
Memorandum
Attached for your review and consideration is a resolution to approve the purchase of laser turbidimeters with controllers from Hach Company (Hach) for $79,776.00. This equipment is required by the State of Michigan to monitor and report the filter effluent turbidity levels at the drinking water treatment plant.

The water treatment plant has 26 carbon filters that it uses during the treatment of the City's drinking water. The effluent water from each of these filters is monitored by one Hach turbidimeter and corresponding controller. These turbidimeters are required for compliance with the Michigan Safe Drinking Water Act.

The existing turbidimeters have reached the end of their service life and are no longer supported by Hach for parts or service. Several of the turbidimeters were recently replaced as part of another project at the water treatment plant and the remaining turbidimeters and controllers must now be replaced to ensure continuous operation and compliance with state regulations.

The City requested a quote from Hach, as they are the sole source product vendor. Hach is the manufacturer, as well as distributor of the turbidimeters and controllers currently being used by the water treatment plant. Purchasing from Hach allows the water treatment plant to maintain consistency in its filter monitoring instrumentation.

Budget/Fiscal Impact: Funds for this project are available in the approved FY 24 Water Treatment Plant Water Supply System's Operations and Maintenance Budget.

Hach Complies with the City's Living Wage and Non-Discrimination Ordinances.
