The Supply Of Aluminum-Based Coagulants And Polymers For Wastewater Treatment

The City of Woodland is soliciting proposals for the supply of aluminum-based coagulants and polymers for its Water Pollution Control Facility in Woodland, California. The contract involves the delivery of aluminum chlorohydrate solution in bulk, estimated at 250,000 pounds annually with loads between 32,000 and 35,000 pounds, as well as approximately 10 totes of polymer or aluminum chlorohydrate solution per year. The base term of the agreement is five years, running from December 16, 2026, to December 15, 2031, with two optional one-year extensions. Deliveries are requested on an as-needed basis and must be completed within five working days of a request, with bulk offloading requiring compressed air supplied by the tractor-trailer. Award selection is based on the most advantageous proposal, considering price, qualifications, experience, and the proposer's operational resources. Mandatory requirements for consideration include California licensing, completion of jar testing, and a lack of conflicts of interest. The selected contractor must provide at least three site visits per year, offer technical support for testing and analysis, and ensure products meet EPA, ASTM, NSF, and ANSI standards. Proposals must be submitted in a sealed envelope by November 12, 2026, and include a firm, irrevocable offer valid for 120 days. Evaluation factors emphasize the ability to meet emergency delivery requirements and the overall capacity to maintain a reliable supply chain.
