UNSPSC 41104202: Deionization or demineralization equipment

UNSPSC 41104202 Deionization or demineralization equipment is a Commodity code covering reverse osmosis (RO) membrane systems, microfiltration equipment, and associated water treatment hardware that state and local water utilities deploy to meet drinking water and recycling facility standards, particularly for PFAS compliance and potable water production. State and local water districts and municipal water treatment authorities dominate the market — West Basin Municipal Water District in California, Collier County and the City of Lubbock in Texas, and the City of Calhoun in Georgia all posted major solicitations within the past four months for RO skids, membrane elements, and complete treatment trains. The scope of work spans turnkey system installation and rehabilitation (removal and replacement of pressure vessels, RO elements, pumps, and controls); supply of membrane elements meeting NSF certification standards; microfiltration pretreatment equipment; and associated spare parts and field support. One solicitation (City of Holly Hill, Florida, sole source procurement for a WesTech drive shaft unit) falls outside the code's primary scope, suggesting occasional miscoding of ancillary equipment procurement.

Recent activity concentrates in California, Florida, Georgia, and Texas. The City of Calhoun, Georgia posted a CMAR (Construction Manager at Risk) opportunity (PE76500NONST2026000000023, due July 30, 2026) for treatment plant upgrades at two drinking water facilities, requiring design and construction of reverse osmosis systems with microfiltration pretreatment; Collier County, Florida advertised sealed competitive bidding (Bid No. 26-8646, due April 24, 2026) for comprehensive RO skid rehabilitation with $4 million anticipated budget; and the City of Lubbock issued an ITB (ITB2619356SR, due March 5, 2026) for a complete reverse osmosis system producing reagent-grade water. West Basin Municipal Water District issued two separate solicitations — a Request for Qualifications for submerged microfiltration membranes (RFQTH0131, closed May 26, 2026) and an Invitation for Quotations for 852 RO membrane elements (IFQTH0119, closed February 26, 2026) for the Carson Regional Water Recycling Plant. These opportunities reflect sustained demand driven by EPA PFAS/MCL compliance mandates and aging membrane replacement cycles, with contract values ranging from under $150,000 for spare parts to $4 million for complete system rehabilitation.
