UNSPSC 47101530: Odor control equipment

UNSPSC 47101530 Odor control equipment (Commodity) covers the chemical additives, mechanical equipment, and integrated services that state and local water and wastewater utilities deploy to suppress hydrogen sulfide odors and mitigate corrosion in collection and treatment infrastructure. Recent solicitations show state and local governments buying ferrous salts and biocides injected directly into wastewater streams, portable and skid-mounted misting systems for landfill and treatment-plant perimeters, New York Blower centrifugal fan systems with carbon adsorbers and biofilters, and comprehensive vendor-supplied dosing controls, hydrogen sulfide monitoring, and emergency response. The issuing bodies are primarily municipal utilities and county departments of water and waste management—the City of Dallas Water Utilities, City of Atlanta Department of Watershed Management, Collier County (Florida), Orange County (California) OC Waste & Recycling, and smaller utility commissions in Connecticut and Georgia—with scope ranging from single-item equipment purchases to multi-year service contracts. Work involves equipment supply, installation, technician labor, and ongoing maintenance; many procurements carry insurance and staffing qualifications tied to hazardous chemicals and wastewater operations.

Recent activity concentrates in the Southeast and Southwest. The City of Dallas is seeking a 36-month ID/IQ contract for ferrous sulfate and ferric chloride injection services with estimated value of $10 million, due June 26, 2026 (BR2600030262), with a mandatory Small Business Enterprise participation goal under its DRIVE policy and a local preference allowing five percent bid deduction.
