UNSPSC 47101546: Grit removal system

A type of device that gathers the sand and soil piled up on the grit chamber and releases to outside.

UNSPSC 47101546 Grit removal system is a Commodity code describing proprietary screening and solids-handling equipment that state and local water and wastewater utilities procure to remove sand, gravel, rags, and other grit from raw water and wastewater treatment processes. State and local buying under this code centers on replacement parts, OEM maintenance, and capital retrofit projects for installed screening and separation equipment; recent solicitations show municipalities acquiring grinder replacement systems, mechanical bar screens, and related drive shaft and actuator components to maintain or upgrade existing treatment infrastructure.

Purchasing bodies issuing under this code are primarily municipal water departments and county water resources departments, including the City of Holly Hill, the City of Tampa, the City of Phoenix, Gwinnett County (Georgia), Collier County (Florida), and the City of Atlanta. Geographic activity concentrates in Florida, Georgia, and Texas, with scattered opportunities in Arizona and other states. Representative recent opportunities include the City of Holly Hill's procurement of a WesTech DS43 Dual Shaft Drive replacement for Softener #2 (sole-source, September 2020 award), Gwinnett County's invitation for bids on Beaver Ruin Diversion Pump Station Grinders Replacements (IFB, bids due November 20, 2026), the City of Phoenix's sealed offers for Sanitaire membrane diffusers for wastewater aeration (IFB-26-0382, five-year contract), and the City of Tampa's request for quotes on Sweco Vibro-Energy Separator replacement parts (RFQ, June 2026). Sole-source and manufacturer-specific notices predominate in this code's recent activity, reflecting the proprietary nature of most treatment equipment and the technical requirement for OEM compatibility; competitive opportunities tend to cluster around annual parts supply contracts or capital construction projects involving grinder or screen replacement at multi-facility systems.
