NIGP 885: Water and Wastewater Treating Chemicals

NIGP 885 Water and Wastewater Treating Chemicals is a Class code encompassing the supply of chemical products used in municipal drinking water treatment, wastewater treatment, and water quality management operations. State and local governments actively procure sodium hypochlorite, liquid aluminum sulfate (alum), chlorine, caustic soda, ferric chloride, polymer, permanganate, fluoride compounds, and specialized treatment chemicals such as corrosion inhibitors, antifoams, and disinfection boosters under this code. Recent solicitations reflect a mix of issuing bodies—water utilities, cities, counties, and regional water authorities—purchasing both commodity chemicals on recurring supply contracts and specialized chemicals for specific treatment processes. Cities of Palo Alto, Santa Cruz, Dallas, and Lewisville; municipalities including Manchester, Connecticut and Meriden, Connecticut; the Great Lakes Water Authority; and county water systems in Florida and Michigan appear as repeat buyers. Work being solicited ranges from straightforward chemical supply contracts (Town of Manchester requesting hydrated lime, sodium hypochlorite, and PACI coagulant for water and wastewater treatment) to integrated service offerings pairing chemical delivery with technical support and optimization consulting, as exemplified by the City of Phoenix's cooling tower water treatment services procurement and Santa Monica's on-call regulatory and treatment optimization support contract.

Geographic activity is concentrated in California, Florida, Texas, Connecticut, Michigan, and North Carolina based on recent postings. The City of Palo Alto (RFQ 197475) is soliciting bulk sodium hypochlorite delivery for its wastewater recycling facility at approximately 130,000 gallons annually with quarterly pricing adjustments; bids are due May 13, 2026, though the original deadline has passed. The Town of Manchester, Connecticut (ITB 25/26-59) issued an Invitation to Bid for water treatment chemicals—hydrated lime, sodium hypochlorite, PACI, liquid chlorine, fluosilicic acid, copper sulfate, sodium fluoride, and zinc orthophosphate—with responses due May 22, 2026, and a contract term running August 1, 2026 through July 31, 2027. The City of Lewisville, Texas posted two separate bids for anhydrous ammonia and activated carbon (RFB 26-87-A and RFB 26-50-A, both due June 15, 2026) to establish primary and secondary supplier contracts for water and wastewater treatment operations. West Travis County Public Utility Agency (RFB 2026-10-01) is seeking bids for six chemical products including aluminum chlorohydrate, liquid ammonium sulfate, polymer, chlorine gas, sodium permanganate, and orthophosphate, with sealed bids due July 9, 2026. The Great Lakes Water Authority (REQ0009487 and REQ0009121) has posted solicitations for sodium bisulfite bulk delivery and job order contracting for water and wastewater project management across Michigan locations. These opportunities typically feature five-year initial terms or one-year contracts with annual renewal options; evaluation emphasizes lowest responsive and responsible bidder, with secondary consideration for local preference, DBE participation, or best-value factors where applicable.
