UNSPSC 47101547: Surface washing device

A type of device that gushes out the high pressure water on the surface of the filter sand in the water treatment facilities for removing the foreign substance precipitated on the surface of filter paper.

UNSPSC 47101547 Surface washing device is a Commodity code representing equipment and services state and local governments procure to clean, treat, and maintain water and wastewater infrastructure—a far broader scope than the code name alone suggests. The actual buying activity encompasses membrane diffusers for aeration basins, reverse osmosis and deionized water system maintenance, chilled and heating water loop treatment services, water treatment chemical supply, polymer blending units, bypass pumping services, hose pump parts, and specialized parts for water conditioning and lime softening systems. State and local water utilities, treatment plant operators, school districts, municipal authorities, and specialized facilities drive procurement under this code, with Texas State University, Collin College, the Tampa Convention Center, Collier County, Gwinnett County, Paulding County, the City of Waxahachie, the City of Phoenix, the City of Tucson, and multiple Florida municipalities and Georgia counties visible as recent buyers.

Recent solicitations span the South and Southwest with particular activity in Texas, Florida, and Georgia. Texas State University issued an RFP for reverse osmosis and deionized water systems maintenance and services due August 10, 2026. Collin College is seeking proposals for a Frisco Campus Chilled and Heating Water Loop Extension (IFB due July 28, 2026) valued at substantial design and construction, while the Tampa Convention Center is bidding comprehensive chilled water and cooling tower treatment services (IFB due July 28, 2026) with emphasis on data-driven optimization and SBE participation. Collier County awarded a $3.29 million lime softening improvements project at its South County Regional Water Treatment Plant (sealed bids due July 15, 2026), and Gwinnett County is soliciting solids dewatering and thickening polymer on annual contract (sealed bids due July 30, 2026) with a four-year initial term and four optional one-year renewals. The City of Phoenix is procuring Sanitaire membrane diffusers for two wastewater treatment plants on a five-year firm fixed-price contract commencing September 23, 2026 (sealed offers due July 2, 2026). Geographic concentration leans heavily toward Florida and Georgia water and wastewater utilities managing regional treatment infrastructure, combined with Texas higher-education and municipal facilities managing distributed systems across multiple campuses or service areas.
