NIGP 92692: Wastewater Facility Odor Monitoring

NIGP 92692 Wastewater Facility Odor Monitoring, an Item code, encompasses chemical treatment services and atmospheric monitoring equipment deployed to detect and control hydrogen sulfide and other hazardous gases at wastewater lift stations, pump stations, and treatment facilities. State and local governments are actively procuring hydrogen sulfide control through chemical injection—hydrogen peroxide and Peroxide Regenerated Iron Sulfide Control (PRISC)—and fixed atmospheric monitoring instruments with sensors, controllers, alarms, and calibration systems designed to detect hydrogen sulfide, methane, oxygen depletion, chlorine, ammonia, ozone, chlorine dioxide, and carbon monoxide across confined spaces, process basins, and underground vaults. Issuing bodies include cities, counties, and regional water authorities; the City of Orlando, City of Phoenix Water Services Department, Orange County, Collier County, the Great Lakes Water Authority, Marion County, and Pasco County all posted opportunities under or closely aligned with this code in recent months.

Recent activity concentrates in Florida and the Southwest, with the City of Orlando posting an IFB for hydrogen sulfide control service at three lift stations due September 9, 2026 (IFB260556); the City of Phoenix Water Services Department soliciting sealed offers for atmospheric monitoring instruments—fixed installations under a five-year contract with DBE-N program participation requirements, offers due September 4, 2026 at 2:00 p.m., with a non-mandatory pre-offer conference August 25, 2026 via WebEx (IFB-27-0435); and Marion County posting a notice of intent for sole-source procurement of HIVENT, HIBOCS, HICARB, and HIVON odor control equipment, media, parts, and services from Heyward Florida Incorporated for wastewater treatment plants and lift stations, with a competition-determination deadline of July 21, 2026 (26SS-111). The Great Lakes Water Authority in Michigan posted a 2027 Job Order Contract RFQ for multi-project water and wastewater management with submittals due August 27, 2026 (REQ0009487). Larger infrastructure bids in the same jurisdictions—Orange County's septic tank retrofit and bridge replacement projects, Collier County's RO treatment skid rehabilitation—indicate sustained public wastewater investment momentum in Florida.
