UNSPSC 47101562: Drum screen

A facility that is made to have the pollutant water with solid matter to flow in to the drum-type rotating screen inside that has the water passes the screen to purify while the solid matter are filtered through the screen to be discharged.

UNSPSC 47101562 Drum screen, Commodity, names a narrow product class that state and local procurement offices rarely buy as a standalone line item. The recent opportunities tagged with this code reveal a pervasive mismatch: the solicitations are for water treatment plant upgrades, wastewater bar screens, chiller and cooling tower maintenance, solids dewatering polymers, pump maintenance, bypass pumping services, grit removal equipment, membrane diffusers, SCADA system integration, and chlorine dioxide generation programs—none of which center on drum screening as a discrete commodity. A drum screen is a rotating cylindrical mesh or bar device used in water and wastewater preliminary treatment to remove solids; it appears in a few of these opportunities as one component within a larger scope (such as the Paulding County Jail Bar Screen, which names a mechanical wastewater bar screen as the primary deliverable, not a drum screen), but the code itself does not capture the dominant procurement activity under these tags.

State and local water utilities, counties, cities, and special districts across the Southeast and Southwest are currently buying water and wastewater treatment system components, parts, services, and upgrades through this code—including Gwinnett County (Georgia), Paulding County (Georgia), Collier County (Florida), Tampa (Florida), Phoenix (Arizona), Calhoun (Georgia), Sanford (Florida), Tucson (Arizona), and others. The most recent and concrete opportunity directly naming a drum or bar screen is Paulding County's two-part sealed bid for mechanical wastewater bar screen installation at the Paulding County Jail (due July 31, 2026, IFB 270020901 and 27002-0901), which involves an 8-foot diameter precast concrete structure, compactor conveyor, and related piping and electrical work. The code shows no coherent recent signal; procurement activity is scattered across water treatment component categories, and the tagging appears to be administrative or system-level rather than aligned to what buyers actually need.
