FROM: Allison Swisher, Director of Public Utilities
SUBJECT:
title
Award of Contract for the 2026 Aluminum Sulfate Purchase to USALCO LLC for the Not-to-Exceed Amount of $792,805.00
end
BACKGROUND:
Aluminum Sulfate solution (alum) is used at the Wastewater Treatment Plants to aid in the removal of phosphorus. The City of Joliet utilizes alum as the only means to remove phosphorus at the Westside Treatment Plant and utilizes it to aid in removal at both the Eastside and Aux Sable Wastewater Plants.
The Public Service Committee will review this matter.
CONCLUSION:
During the Aluminum Sulfate 2024 bid the City requested that all bidders submit optional second year and third year pricing. USALCO LLC, the low bidder, submitted a 2026 bid price of $1.2197 per gallon (not to exceed $792,805.00), for the estimated 650,000 gallons needed, which is a 4% increase from the 2025 price but 36% lower than the next lowest bidder’s proposal. City Staff recommends exercising the 2026 option. Bulk deliveries will be ordered on an as-needed basis.
Funds will be charged to the Water & Sewer Operating Fund / WSTP / Chemicals (Org 50080803, Object 536108, $496,260.10), Aux Sable / Chemicals (Org 50080804, Object 536108, $152,074.00), and ESTP / Chemicals (Org 50080802, Object 536108, $144,470.90).
