NIGP 03169: Odor Control Equipment (Indoor)

NIGP 03169 Odor Control Equipment (Indoor), an Item code, encompasses supplies and services for neutralizing odors in enclosed municipal facilities and wastewater infrastructure. State and local governments procure wall-mounted battery-operated dispensers, chemical dosing systems, hydrogen sulfide monitoring equipment, and associated refills and maintenance services to manage odors in police departments, water utilities, fire stations, convention centers, wastewater treatment plants, and lift stations. The issuing bodies include cities, county utilities, and water resource departments across multiple states.

Recent solicitations show activity concentrated in the Southeast and Southwest. The City of Phoenix issued IFB-26-0067 in March 2026 (due April 3, 2026) for a five-year odor control services contract covering 82 city sites with an estimated 2,750 odor control devices annually and metered mist systems; the procurement carries DBE and small business participation plan requirements. The Waterford Utility Commission in Connecticut issued a bid solicitation in April 2026 (due April 21, 2026) for comprehensive odor and corrosion control chemicals including 35,000 gallons yearly of Bioxide AQ, dosing controller systems at seven pump stations, hydrogen sulfide monitoring equipment, and emergency response services. Smaller-scale activity appears in lift station projects at the City of Orlando (Lift Station 2 Replacement, IFB26-0036, due January 29, 2026, and five lift stations project, IFB26-0001, due April 30, 2026), which involve ancillary odor management as part of broader wastewater infrastructure replacement. Activity also appears in water treatment operations—Gwinnett County, Georgia issued a bid for particle counters at filter plants in March 2026 (due May 8, 2026) that indirectly support water quality monitoring. Florida and Georgia municipalities dominate recent opportunity volume, with secondary activity in Connecticut and Arizona.
