NIGP 89001: Air Flotation Systems (for Water Treatment Removal of Hydrocarbons)

NIGP 89001 Air Flotation Systems (For Water Treatment Removal Of Hydrocarbons), an Item code, encompasses the purchase and maintenance of water treatment equipment and services that state and local governments use to remove suspended solids, hydrocarbons, and contaminants from cooling tower systems, chilled water loops, and municipal water supplies. Recent solicitations show that state and local buyers are acquiring full-service water treatment programs—including chemical supply, equipment provision, installation, monitoring, maintenance, and regulatory testing—rather than purchasing flotation equipment in isolation. Issuing bodies span school districts, municipal water utilities, convention centers, and county environmental departments. The DeKalb County School District solicited HVAC water treatment services across 98 facilities (RFP 27-812, due October 22, 2026), while the City of Waxahachie, Texas sought a comprehensive chlorine dioxide generation program for two municipal water treatment plants operating at 9 and 10 MGD capacity (RFP 202654, due May 28, 2026). The Tampa Convention Center issued a bid for chilled water and cooling tower treatment with data-driven optimization (RFP, due July 28, 2026), and the City of LaGrange, Georgia procured multiple water treatment chemicals including liquid sodium chlorite and liquid chlorine for its Filter Plant and Wastewater Treatment Plant (sealed bid, due June 8, 2026).

Recent procurement activity concentrates in Georgia and Texas, with additional activity in Arizona and broader municipal water utility procurement. The City of Phoenix Water Services Department solicited atmospheric monitoring instruments-fixed for hazardous-gas detection at water and wastewater facilities under DBE-N guidelines (IFB-27-0435, due September 4, 2026), while Henry County, Georgia sought annual groundwater and methane gas monitoring services at closed landfills with a local-vendor preference (RFP #27-06, due September 10, 2026). The City of Fairburn, Georgia issued an RFP for retention pond cleaning and sediment removal (RFP 26-008, due June 4, 2026), and the City of Cumming, Georgia solicited construction proposals for clearwell improvements including a six-million-gallon clearwell installation (RFP, due June 26, 2026, with mandatory pre-proposal conference May 12, 2026). Hartsfield-Jackson Atlanta International Airport (City of Atlanta) requested grease interceptor maintenance and inspection services (RFP/GS/DOA/2604-1260177, due June 29, 2026). Pricing structures are typically unit-price or all-inclusive models with firm pricing for the initial contract period and capped annual increases thereafter; evaluation emphasizes technical qualifications and experience alongside cost.
