Bids are requested for liquid sodium 50/50 ortho/poly phosphate blended corrosion inhibitor for reducing lead, copper and iron concentrations at the tap of the City of Minneapolis water consumers. The bid is to furnish the corrosion inhibitor for a twelve-month period beginning December 1, 2024. Product is to be delivered by either of two means: Delivery by tank truck of approximately 4,000 (four thousand) gallon capacity or in Intermediate Bulk Containers (“Totes”) of approximately 300 (three hundred) gallon capacity. The product to be supplied, the handling, packing, shipping, and testing thereof, except where otherwise herein specified, shall conform to accepted industry standards. The product shall possess ANSI/NSF Standard 60 certification. The product must comply with AWWA standards B504 and/or B505 as applicable (latest versions). Quantities in this specification are presented as total pounds PO4 due to the varying total phosphate content of available products.

The approximate split between delivery needs is 30,000 pounds PO4 by tote supply and 160,000 pounds PO4 by tank truck.
