The Trinity River Authority of Texas is seeking a subcontractor to supply a chemically stable liquid blend of aluminum sulfate and copper sulfate specifically formulated for water treatment applications, with strict adherence to AWWA B403-09 standards. The blend must maintain consistent chemical integrity under storage and delivery conditions, and the supplier is required to provide ongoing technical and laboratory support to optimize copper ion concentrations, ensuring efficacy in pathogen control and water quality management without exceeding regulatory thresholds. This procurement emphasizes performance reliability, precise formulation, and continuous collaboration with the agency's water treatment team to calibrate copper dosing based on real-time operational needs. Delivery must be made to a designated location within Texas, though specific site details are not specified, and the contract is structured as a subcontract under NAICS code 325311 for chemical manufacturing. Proposals are due by August 13, 2026, with the solicitation open since July 23, 2026. The supplier must demonstrate proven experience in producing stabilized metal sulfate blends for municipal water systems and show capability to document compliance with industry standards through validated testing and quality control procedures. Long-term reliability and responsiveness to technical adjustments are critical, as the blend’s performance directly impacts public health and regulatory compliance in the region’s water infrastructure.
