UNSPSC 47101540: Chemical feeder

The equipment used to feed a proper amount of chemicals such as coagulant and coagulant aids according to water quality or water flow in treatment of water supply and industrial water.

UNSPSC 47101540 Chemical feeder is a Commodity code covering specialized chemical-delivery equipment and systems that state and local governments procure to support water treatment, wastewater reclamation, and facility operations. The code captures a range of equipment—from polymer blending units and lime slaking systems to chlorine dioxide generation systems, water treatment chemical feeders, and associated controls—deployed across municipal water plants, wastewater treatment facilities, and institutional infrastructure. Recent state and local activity reflects sustained investment in chemical treatment infrastructure modernization, particularly at water reclamation facilities serving mid-to-large regional systems; universities (Texas State University); and school districts and special districts managing chilled water and heating systems. Procurement bodies span state departments (Texas State University, California Caltrans), county water utilities (Collier County, Gwinnett County, Orange County), municipalities (Tampa, Phoenix, Waxahachie, Sanford, LaGrange, Calhoun, Cumming, Gray, Holly Hill, Winter Park), and special districts (Eastern Municipal Water District in California; School Board of Seminole County). Issuing bodies repeat frequently—Gwinnett County, Collier County, and the City of Tampa each appear multiple times in recent solicitations—indicating steady, recurring demand for chemical feeder parts, replacement units, maintenance contracts, and full-system upgrades.

The geographic spread reflects concentrated activity in Florida (Tampa, Palm Bay, Winter Park, Holly Hill, Sanford, Collier County) and Georgia (Gwinnett County, Athens-Clarke County, LaGrange, Calhoun, Rome, Gray, Cumming, Columbia County), with secondary activity in Texas (Waxahachie, Huntsville), Arizona (Phoenix), California (Riverside County, Caltrans statewide), and Oregon. Representative recent opportunities include the Tampa Convention Center solicitation (IFB 26P00432, due July 28, 2026) for comprehensive water treatment services including chemical feed equipment and monitoring technologies for chilled water and cooling tower systems; Gwinnett County's polymer procurement (PE77023NONST2027000000655, due July 30, 2026) for solids dewatering and thickening polymer on a four-year annual contract with optional renewals; the City of Waxahachie's RFP (RFP202654, due May 28, 2026) for a full-service chlorine dioxide generation program covering equipment, chemicals, and maintenance at two municipal water treatment plants operating at 9 and 10 MGD; the City of Calhoun RFP (PE76500NONST2026000000023, due July 30, 2026) for CMAR services to design and build reverse osmosis treatment systems with chemical feed systems for PFAS compliance at two drinking water facilities; and the City of LaGrange bid (PE74150NONST2026000000025, due June 8, 2026) for water and wastewater treatment chemicals including powdered activated carbon, liquid aluminum sulfate, sodium chlorite, and chlorine across an annual contract term. Sole-source and single-source procurements appear regularly (Collier County, Holly Hill, Winter Park, Hillsborough County), reflecting the technical specificity of proprietary equipment and the integration constraints of installed systems. Set-asides and preferences are minimal; one exception is the Calhoun CMAR procurement, which may include local participation scoring.
