Memorandum 19-005 Water Treatment Plant Chlorine Generation Cell Replacement

Memorandum 19-005

TO:                        Katie Koester, City Manager

FROM:                 Carey S. Meyer, Public Works Director            

DATE:                   January 8, 2019

SUBJECT:          Water Treatment Plant Chlorine Generation Cell Replacement

Chlorine for the disinfection of the City’s drinking water is generated on-site using a chlorine generation cell. This cell failed late in 2018. Public Works shipped the cell to the manufacturer in hopes that it could be refurbished. The cell cannot be rebuilt and replacement is necessary.

In the meantime, water treatment personnel are batching chlorine to provide for disinfection.

Public Works has been exclusively using Miox chlorine generation equipment. The purchase of a new cell will be a sole source procurement. The cell is being purchased directly through the manufacturer, providing the City with the best possible price.

The estimate attached as back up is for $23,200 and staff has confirmed the shipping cost is $400, bringing the total cost to $23,600.

Recommendation: The City Council amend the 2019 capital budget to create a Water Treatment Plant Chlorine Generation Cell Replacement project, and authorize the expenditure of $23,600 to purchase a replacement cell. The authorization should include approval for a sole source procurement.
