Resolution to Approve Bulk Chemical Purchases for Sodium Hypochlorite (Olin Corporation - $100,500.00/year), Hydrofluosilicic Acid (Mosaic- approximately $20,000.00/year), Pebble Quicklime (Carmeuse Lime - approximately $673,500.00/year) and Ferric Chloride (PVS Technologies - approximately $35,500.00/year) for the Water and Wastewater Treatment Plants (estimated $748,000.00/year)
Memorandum
Your approval is requested to authorize the purchase of bulk chemicals - sodium hypochlorite, hydrofluosilicic acid, pebble quicklime, and ferric chloride - used in treatment processes at the water and wastewater treatment plants (WTP and WWTP).
In 2018, bids were obtained through the Mid-Michigan Drinking Water Consortium Bulk Chemicals Bid. The Consortium was formed in 2014 by mid-Michigan area utilities that soften drinking water with quicklime, to address chemical supply quality, competitive pricing, and residual disposal.
