Title
Resolution to Approve Bulk Chemical Purchases for the Water and Wastewater Treatment Plants of Sodium Hypochlorite (Olin - approximately $106,500.00/year), Hydrofluorosilicic Acid (Univar- approximately $23,800.00/year), Pebble Quicklime (Graymont - approximately $719,500.00/year) and Ferric Chloride (PVS Technologies - approximately $50,320.00/year) (estimated $830,620.00/year)
Memorandum
Your approval is requested to authorize the purchase of bulk chemicals (sodium hypochlorite, hydrofluorosilicic acid, pebble quicklime, ferric chloride), which are used in treatment processes at the City's Water and Wastewater Treatment Plants (WTP and WWTP).
In 2020, 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.
Consortium members include: Lansing Board of Water and Light; City of Battle Creek; City of Jackson; City of Howell; City of Ann Arbor; City of Fenton; East Lansing Meridian Water & Sewer Authority; Plainfield Township; City of Owosso; Marion-Howell-Osceola- Genoa Water Authority; and Tri-County Regional Planning Commission.
Sodium Hypochlorite
The WTP uses sodium hypochlorite to maintain disinfection of drinking water in the distribution system. The estimated cost of this chemical for FY21 is $106,500.00/year for approximately 150,000 gallons.
Sodium Hypochlorite bids were as follows:
1. Olin, $0.71 per gallon
2. JCI Jones, $0.728 per gallon
3. Alexander Chemical, $0.739 per gallon
4.
Hydrofluosilicic Acid
The Center for Disease Control (CDC) has established that 0.7 milligrams per liter (mg/L) of fluoride in drinking water is safe, healthy, and effective for preventing tooth decay. The City's source water contains approximately 0.3 mg/L of fluoride. The City uses hydrofluorosilicic acid to adjust the fluoride level to meet CD...
