NIGP 03169: Odor Control Equipment (Indoor)

NIGP 03169 Odor Control Equipment (Indoor), an Item code, encompasses specialized equipment and services state and local governments procure to manage odorous gases at treatment facilities, utility operations centers, and confined spaces. Recent solicitations reveal that jurisdictions are buying fixed atmospheric monitoring instruments with sensors and alarms designed to detect hydrogen sulfide, methane, oxygen depletion, chlorine, ammonia, ozone, chlorine dioxide, and carbon monoxide; proprietary odor control media and replacement parts; installation, commissioning, and operator training; and preventative maintenance and repair services on boiler and chiller systems that generate or contain odorous byproducts. Issuing bodies include large cities with water and wastewater operations (Charlotte, Phoenix) and county-level wastewater authorities (Marion County), alongside regional purchasing cooperatives like Sourcewell that aggregate demand across multiple jurisdictions. The work typically requires vendor qualifications including manufacturer certifications, local parts stocking, trained and certified technicians, and the ability to service specialized equipment from multiple original equipment manufacturers.

Geographic activity centers on North Carolina, Arizona, and Florida, with broader multi-state reach through cooperative purchasing vehicles. Representative recent opportunities include the City of Phoenix Water Services Department issuing IFB 27-0435 for atmospheric monitoring instruments—fixed installations with a five-year term, firm-and-fixed pricing for the initial year, sealed-offer submission due September 4, 2026, and a mandatory pre-offer conference on August 25, 2026; and the City of Charlotte posting RFP 26920271769 for boiler and chiller maintenance and repair services at CATS facilities, with proposals due October 15, 2026. Marion County Procurement posted a notice of intent on July 13, 2026 for sole-source procurement of HIVENT, HIBOCS, HICARB, and HIVON odor control equipment and services from Heyward Florida Incorporated for use at wastewater treatment plants and lift stations, though this does not constitute an open competitive solicitation.
