Sodium hydroxide 30% (caustic soda)

The City of Ukiah is seeking bids for sodium hydroxide 30% (caustic soda) for its Water Treatment Plant through a Request for Bid (RFB) issued on September 19, 2025. The procurement targets approximately 20 dry tons of chemical product that must meet A.W.W.A. Standards B501-88 or its current version, with mandatory chemical certification proof. Bidders are required to submit proposals by October 17, 2025, at 1:30 p.m., with emailed submissions accepted at the Purchasing Manager's office. The contract will cover a one-year period from the award date, with typical delivery orders of 4,000 gallons or 6.66 dry tons, and a required delivery window of three calendar days from order receipt. Vendors must quote prices freight off-loaded at designated City locations, excluding state, local, and federal taxes, and must comply with DOT Hazardous Materials regulations and OSHA standards. The City reserves the right to accept or reject any bids and will award the contract to the lowest overall bidder, with the bid remaining open for 60 days from the due date.

The procurement offers a local vendor preference of 5% (up to $2,500) for vendors conducting business in Mendocino County, California. Successful bidders must possess a current City of Ukiah business license and provide comprehensive insurance certificates. While no specific set-aside designations for disadvantaged enterprises are mentioned, the bid appears open to qualified vendors who can meet the technical specifications and regulatory requirements. Invoices for Water Treatment Plant deliveries will be non-taxable, and the contract suggests routine chemical supply needs for municipal water treatment operations. Though specific budget ranges are not explicitly stated, the procurement indicates an anticipated annual volume of approximately 20 dry tons of sodium hydroxide, which would represent a moderate-value municipal supply contract for chemical materials.
