UNSPSC 47101503: Carbon filtration equipment

UNSPSC 47101503 Carbon filtration equipment is a Commodity code capturing state and local procurement of water treatment filtration systems, membranes, media, and related equipment that remove particulates, microorganisms, and contaminants from drinking water, wastewater, and recycled water streams. Recent solicitations show state and local agencies buying reverse osmosis and deionized water systems maintenance, replacement sand and carbon filter media, microfiltration membrane modules, particle counters, and turnkey installation and service for operating treatment plants. The issuing bodies span water utilities (municipal water districts, county water departments), state agencies managing multi-facility water systems, and city departments operating drinking water and wastewater treatment infrastructure. Texas State University, Hillsborough County, Collier County, and West Basin Municipal Water District appear repeatedly as active buyers. Geographic activity concentrates in Florida (Hillsborough and Collier Counties), California (West Basin), Texas (Texas State University), Georgia (Gwinnett County, City of Atlanta), and Connecticut (City of Meriden), with additional activity in North Carolina and Arizona.

Representative recent opportunities include Texas State University's RFP for reverse osmosis and deionized water systems maintenance and services with proposals due August 10, 2026; Hillsborough County's sole-source procurement for deionized water systems maintenance from Thomas Water Purification LLC, with an estimated contract value of $76,530 over two years and a challenge deadline of July 14, 2026; West Basin Municipal Water District's Request for Qualifications for submerged microfiltration membranes pre-qualification for the Edward C. Little Water Recycling Facility, with SOQs due May 26, 2026; and Collier County's sealed bid for SCRWTP lime softening improvements including blend tank construction and associated chemical injection systems, with bids due July 1, 2026 and an anticipated project budget of $3.29 million. The California Department of Water Resources issued an Invitation for Bid on comprehensive water treatment system services across the State Water Project's four field divisions, with bids due June 9, 2026 and a mandatory pre-bid conference on May 26, 2026; the contract includes DVBE participation requirements of a minimum 3 percent and prevailing wage compliance. Fort Worth's RFP for filter media on an as-needed basis establishes a 30 percent small business goal, while several sole-source procurements for proprietary equipment (Fluid Control Specialties for Hillsborough County at $1,458,835 estimated value, DXP Enterprises for Hillsborough County at $6,600,000 estimated value) indicate vendor lock-in around incumbent systems integration.
