ITEM SUMMARY:
Hydrated Lime is one of the various chemicals used at the City’s Water Treatment Plant. Approximately
1,300 tons of Hydrated Lime are used annually. Hydrated Lime is the key component to our softening
process. Hydrated lime reacts with existing bicarbonate salts (Calcium, Magnesium, and most
importantly, Radium) and converts them to insoluble carbonate salts, thus removing them to a great
degree from the treated water.
A Notice to Bidders was advertised in the Daily Herald on October 3, 2023, as well as on the online
bidding platform, QuestCDN, and sealed bids were opened on October 24, 2023. There were two (2)
bids received. The results are below.
Bidder Bid Amount Overall Rank
Mississippi Lime Company $419,302.00 1
Carmeuse Lime & Stone $664,456.00 2
The low bidder was Mississippi Lime Company of St. Louis, Missouri, for a total contract price of
$419,302.00 ($322.54/ton delivered). This represents a 19.53% increase over FY 2023 unit prices
($269.85/tons delivered). The increase is largely attributed to increases in energy costs, fuel surcharges,
inflationary economic environment, and driver shortages. A bid tab showing the results of the bid
opening is attached for reference. It should be noted staff has been able to achieve operational
efficiencies in the past year to reduce the amount of lime that is being used in the treatment process,
reducing the annual quantity from 1,900 tons to 1,300 tons.
Staff recommends that a contract be awarded to Mississippi Lime Company for the procurement of
Hydrated Lime, at a unit price of $322.54/ton delivered, for an amount not to exceed $419,302.00 for FY
2024.
Adequate funds will be budgeted in the Water Fund, Water Treatment Plant Operations — Chemicals (06-
34-48-4626) to cover this expenditure in FY2024.
