Title
Resolution to Award a General Services Agreement for Removal of Water Treatment Plant Residual Limestone to Prolime Corporation, Bid No. ITB-4594 (estimated $325,600.00/yr)
Memorandum
Your approval is requested to award a three year general services agreement to Prolime Corporation for the removal of Water Treatment Plant residual limestone

Limestone residual is generated at the Water Treatment Plant as a result of the water softening process. The limestone residual has been designated an agricultural liming material by the Michigan Department of Agriculture and can be recycled by applying it to farmland. Additionally, it has been approved as a soil ad-mixture to fill gravel pits.

A complete pressing and discharge of residual from one of the filter presses the Water Treatment Plant is termed a "dump". A dump is approximately seven (7) cubic yards and weighs eight (8) tons. The plant produces approximately 2,200 dumps per year. At $148.00 per dump the estimated first year contract would be $325,600.00. After the first year, the contract provides for annual adjustments to the unit price based upon 80% pf the Consumers Price Index. The estimated three year cost is $976,800.00.

The City received the following bids:
Prolime Corporation $148.00/dump

It is recommended that Council accept the bid and award a general services agreement to Prolime Corporation, for the removal of residual limestone at the Water Treatment Plant.

It is also recommended that the contract may be extended for up to two additional one-year periods with the same price escalation terms for years two and three, if the vendor is agreeable and if in the best interest of the City.

Budget/Fiscal Impact: Funds are budgeted in the FY20 Operations and Maintenance Budget for the Water Supply System Fund. In FY21-24, the agreement is predicated on the appropriate funding from Council.
