UNSPSC 40161609: Water purification system

Its purpose is the elimination of pathogenic microorganisms contained in water that have not been eliminated in the initial stages of water treatment.

UNSPSC 40161609 Water purification system is a Commodity code that encompasses replacement components, analytical monitoring equipment, treatment chemicals, and circulation systems that state and local water utilities deploy to treat potable water and manage water quality. The code sees activity across municipal water departments, regional water authorities, and specialized water treatment plants procuring equipment ranging from mechanical drive shafts for treatment tanks to analytical instrumentation, chemical supplies for coagulation and disinfection, and aeration systems to prevent algae growth and fish kills. Issuing bodies include city water treatment departments (City of Holly Hill, City of LaGrange), regional water supply authorities (Tampa Bay Water), and state resource agencies (Utah Division of Wildlife Resources). Recent solicitations show two distinct procurement paths: sole-source acquisitions when utilities are locked into proprietary equipment ecosystems, and competitive sealed-bid procurements for commodity chemical inputs where multiple suppliers can meet specifications.

Activity appears concentrated in the Southeast and intermittently in the Mountain West. The City of Holly Hill, Florida issued a sole-source notice in October 2026 for a replacement drive shaft unit (WesTech DS43 Dual Shaft) for softener #2 at its water treatment plant, valued at $113,067.00, due September 22, 2020 (though posted much later), comprising equipment and turnkey installation services. Tampa Bay Water, a regional water supply authority in Florida, posted a sole-source notice of intent on October 6, 2026 to procure Evoqua/Wallace & Tiernan analytical equipment, replacement parts, and consumable supplies from Water Treatment & Controls Technology, Inc., with an objection period closing October 27, 2026. The City of LaGrange, Georgia issued a sealed-bid solicitation (IFB) on May 7, 2026 for water and wastewater treatment chemicals including activated carbon, aluminum sulfate, sodium chlorite, liquid chlorine, and ferric chloride, with sealed bids due June 8, 2026 at 2 p.m. EST. The State of Utah Division of Purchasing issued an IFB on May 4, 2026 for a solar-powered lake water circulator system for Matt Warner Reservoir with a response deadline of May 13, 2026 and a project budget of $66,800.
