UNSPSC 41104805: Nitrogen blowdown evaporators

UNSPSC 41104805 Nitrogen blowdown evaporators is a Commodity code that state and local governments are procuring under for wastewater treatment and land application consulting services, specifically engineering support for operating nitrogen and water balance models at municipal wastewater facilities. The City of Lubbock's recent solicitation shows that buying under this code centers on day-to-day operational modeling and maintenance of high-nitrate wastewater treatment systems designed to prevent groundwater contamination through balanced crop uptake at agricultural land application sites. Issuing bodies soliciting under the code include municipal wastewater authorities managing permitted land application operations, with professional engineering services being the primary deliverable rather than equipment procurement alone.

The City of Lubbock, Texas posted RFQ2619882SR on September 1, 2026, seeking Statements of Qualifications from engineering firms to operate water and nitrogen balance models at the Lubbock Land Application Site and Hancock Land Application Site, with responses due September 30, 2026. The scope requires day-to-day model operation and maintenance to ensure compliance with Texas Commission on Environmental Quality wastewater permits and prevent nitrate leaching into groundwater. Qualified firms must demonstrate professional engineering expertise in wastewater treatment, agronomy, hydrogeology, or related disciplines sufficient to manage nutrient cycling and water balance in agricultural land application settings. The source does not identify other recent opportunities under this code or specify contract value, term length, or geographic reach beyond the Lubbock area.
