NIGP 885: Water and Wastewater Treating Chemicals

NIGP 885 Water and Wastewater Treating Chemicals, a Class code, encompasses bulk chemical commodities that state and local governments procure for potable water treatment, wastewater disinfection, and facility operations—including sodium hypochlorite, liquid chlorine, caustic soda, sulfuric acid, aluminum sulfate (alum), polymers, and specialized process chemicals. Recent solicitations reveal counties, cities, water authorities, and special-purpose districts purchasing these chemicals under firm-fixed or requirements contracts, typically with annual volumes measured in hundreds of tons and spending ranging from $130,000 to $4.27 million annually depending on facility scale. Collier County, Florida (Bid 268705, ITB, due November 13, 2026) is seeking countywide chemicals for water and wastewater treatment across multiple regional plants and recreation facilities—29 line items spanning ammonia, carbon dioxide, chlorine, sulfuric acid, sodium hydroxide, and polymers with annual historical spending approximating $4 million. The City of Tolleson, Arizona (IFB 26013) seeks bulk sodium hypochlorite and hydrochloric acid for wastewater treatment. San Angelo, Texas issued multiple rebid ITBs for liquid chlorine (due August 6, 2026), caustic soda, coagulant (including mandatory pre-qualification testing), and liquid ammonium sulfate. The City of Greenville, Texas (IFB 2026ANNUALSUPPLIES069) sought 80 tons annually of liquid chlorine and sulfur dioxide; the City of Palo Alto (RFQ 197475) requested bulk 12.5% sodium hypochlorite delivery at approximately 130,000 gallons annually. These procurements are spread across Texas, Florida, Arizona, California, and Connecticut, with state and local water utilities, county commissioners' offices, and municipal water departments as the primary buyers.

Issuing bodies include county government (Collier, Orange, Sarasota, Broward, Great Lakes Water Authority), municipal water departments and public utilities (Phoenix, Tucson, Arlington, Santa Monica, Palo Alto, San Angelo, Greenville, Santa Cruz, Tolleson), and independent authorities. Several opportunities span multiple facility types within single jurisdictions—water treatment plants, wastewater facilities, parks, and distribution/collection infrastructure. Local-vendor preferences appear in some procurements (Collier County's local-business certification option), and one Broward County solicitation (RFI BLD6232026F23, June 24, 2026) sought to determine sole-source justification for DeZurik/APCO valves and repair services, a companion procurement to chemical delivery systems. Pricing in recent bids incorporates AWWA and NSF 60 compliance; delivery within 2–5 business days; firm pricing for 180+ days; volume commitments with no guaranteed minimums; and F.O.B. destination with all transportation costs included. Requirements contracts dominate the structure, with annual renewals common. Incumbent or repeat vendors (such as Heartland Water Technology for concentrator systems in Hillsborough County, noted in a sole-source notice, SS2600313) indicate established supply chains, though multi-award structures and open competitive rebids suggest active market churn. Geographic concentration is highest in Florida (Collier, Orange, Sarasota, Broward, Hillsborough counties) and Texas (San Angelo, Greenville, Arlington, Tolleson), with secondary activity in Arizona, California, and Connecticut, reflecting urban water infrastructure scale and recurrent treatment-chemical demand in growing and established water systems.
