This is an Invitation to Bid (ITB 26-15) issued by the Town of Groton, Connecticut for the supply of liquid calcium nitrate to the Water Pollution Control Division. The product will be used as a biocide to remove hydrogen sulfide and prevent odor and corrosion within the wastewater collection and treatment systems. The Town estimates an annual requirement of 15,000 to 30,000 gallons, to be delivered in shipments of approximately 2,000 to 3,800 gallons between 8:00 a.m. and 2:00 p.m., Monday through Friday, with a minimum 48-hour notice requirement. The solicitation opened on April 1, 2026, at 8:30 a.m. EDT, with bids due by May 1, 2026, at 2:30 p.m. at the Purchasing Office, Groton Town Hall, 45 Fort Hill Road. The contract will be valid through June 30, 2027. No bidders' conference or site visit is specified in the solicitation documents.

Bidders must submit pricing on a delivered, FOB Groton basis, expressed as cost per gallon, with all charges including freight, technical assistance, and delivery included in the per-gallon price. The liquid calcium nitrate must meet specific technical specifications including a minimum of 3.5 pounds of nitrate-oxygen per gallon and a minimum specific gravity of 1.45.

All vendors are eligible to respond, with no stated set-asides for disadvantaged enterprises. No estimated total contract value is listed, though the annual requirement range provides a basis for prospective bidders to estimate potential revenue.
