Approve Specifications and Authorize Advertisement for Bids for Surface Water
Treatment Facility Aluminum Chlorohydrate Chemical Supply
September 3,2014
Public Works Director
REGOMMENDED ACTION Approve specifications and authorize advertisement for bids for
Surface Water Treatment Facility aluminum chlorohydrate chemical
supply.
BACKGROUND INFORMATION: The Surface Water Treatment Facility operation requires the
purchase of several different chemicals commonly used to treat
municipal drinking water. Through the competitive bidding process,
chemicals purchased include hypochlorite, salt soda ash, sodium bisulfite, citric acid, and sodium
hydroxide. ln addition to these chemicals, aluminum chlorohydrate (ACH) is required for the treatment
process to meet total organic carbon removal requirements established by the Water Resources Control
Board, Division of Drinking Water.
The City previously purchased ACH through CalChem Enterprises in the amount of $59,616 for
FY 2013114. At the time of purchase, CalChem was the only manufacturer in California and is located in
Modesto, approximately 42 miles from the Surface Water Treatment Facility. This close proximity
minimized freight costs, in addition to providing a lower cost by purchasing directly from the manufacturer
versus a chemical supplier.
It was staff's recommendation at that time that City Council exercise Lodi Municipal Code Section
3.20.070, Bidding, stating the bidding process may be dispensed when the City Council determines that
the purchase or method of purchase is in the best interest of the City.
Due to the increased use of ACH by municipal water/wastewater facilities, a number of aluminum
manufacturing facilities have begun producing and selling ACH. Staff believes that this increase may
create a competitive market and may drive down the cost of the product. Statf recommends City Council
approve the specifications and authorize advertisement for bids.
FISCAL IMPACT Funds for ACH are budgeted in the Water Operations budget.
FUNDING AVAILABLE: Funding will be identified at contract award
