Supply of liquid aluminum sulfate

The Harlingen Waterworks System (HWWS) is seeking proposals for Bid No. 25-018, which involves the procurement of approximately 1,500,000 pounds of liquid aluminum sulfate (Alum) for water treatment purposes. The contract will supply Alum to two water treatment plant locations in Harlingen, Texas: the Downtown Water Treatment Plant at 412 N. 3rd Street and 2525 Dixieland Drive. Bidders must provide Alum that meets specific chemical specifications, including ANSI/AWWA B403-93 Standard for Alum NSF and approval from the E.P.A. and Texas Department of Health for potable water treatment. The chemical must meet precise requirements for specific gravity, aluminum content, iron content, and pH levels. Delivery specifications require shipments of 3,000-4,500 gallons per load, with delivery within three calendar days of order placement, accepted Monday through Friday between 8:00 a.m. and 3:00 p.m. The bid is scheduled to be opened on Wednesday, July 2, 2025, at 2:30 p.m., with a target award date of July 23, 2025. The contract is structured for an initial one-year term with two optional one-year extensions, potentially allowing for a total contract duration of three years.

While no specific set-aside designations or restrictions for disadvantaged enterprises are explicitly mentioned in the documentation, the bidding process will require successful vendors to perform bench tests in HWWS's laboratory to confirm product effectiveness. Vendors will need to provide additional documentation, including references, insurance coverage, and material safety data sheets. The bid does not specify an exact budget range, but the substantial volume of 1,500,000 pounds of Alum suggests a significant contract value. Interested bidders will need to demonstrate technical capability, chemical compliance, and reliable delivery logistics. The procurement is specifically for Cameron County, Texas, through the Harlingen Waterworks System, and will require vendors to meet stringent chemical and delivery specifications. Potential bidders should carefully review the comprehensive bidding package to ensure full compliance with the technical requirements and delivery expectations outlined in the solicitation.
