Water treatment chemical – liquid ammonium sulfate (LAS)

The Orange Water and Sewer Authority (OWASA) is seeking sealed bids for Liquid Ammonium Sulfate (LAS) used in water treatment processes, with the procurement covering 3-4 tank truck loads totaling 135,000 to 180,000 pounds annually. The solicitation, designated as Invitation for Bid (IFB) No. 26-001, requires the chemical to meet specific technical specifications, including a 39-41% ammonium sulfate concentration, domestic production from domestic raw materials, and compliance with ANSI/AWWA B302-16 and NSF-60 standards. Bidders must submit comprehensive documentation including Safety Data Sheets, Certificates of Analysis, references, and compliance forms such as E-Verify and Non-Collusion Affidavits. The bid evaluation will be conducted on a pass/fail basis, considering factors like product documentation, delivery lead time, and references. Key dates include the bid issuance on October 7, 2025, with sealed bids due on October 28, 2025, at 3:00 p.m. ET, followed by a public bid opening at 3:30 p.m. ET at OWASA's Administration Building located at 400 Jones Ferry Road in Carrboro, North Carolina.

The solicitation does not explicitly indicate specific set-aside designations or restrictions for disadvantaged enterprises. The current supplier of liquid ammonium sulfate is Univar Solutions, who was most recently providing the chemical at a price of $0.3467 per pound. The initial contract term is one year, with options to extend for two additional one-year periods, and OWASA may request additional tote containers of approximately 330 gallons alongside tank truck deliveries. The agency reserves the right to reject any or all bids and may conduct performance analysis to ensure the product meets their specifications, with the potential to void the contract if performance expectations are not met. Pricing will be evaluated on a per dry pound basis, with potential price adjustments using the Producer Price Index for Basic Organic Chemicals. Vendors with questions about the bid are directed to contact Allison Spinelli, Director of Water Resources, at aspinelli@owasa.org. While a specific budget range is not provided, the annual volume suggests a significant procurement value for the liquid ammonium sulfate.
