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 that describes mechanical or automated equipment and related services for the removal of grit, sand, and coarse solids from wastewater and water treatment influent streams. State and local water and wastewater utilities procure grit removal systems as standalone capital equipment replacements, as part of broader preliminary treatment upgrades, and as integral components of treatment plant modernization or capacity expansion projects. The equipment typically includes mechanically cleaned bar screens, dual auger compactor units, and rake-based screening assemblies that separate solids before they reach downstream treatment processes. Recent solicitations also show procurement of replacement parts, maintenance services, and retrofit installations for existing grit removal equipment at operating facilities.

The issuing bodies are predominantly municipal water departments, county water and wastewater utilities, and special-purpose water treatment agencies across the Southeast, Mid-Atlantic, Southwest, and West. Collier County, Florida; City of Huntsville, Texas; City of Palm Bay, Florida; and Paulding County, Georgia appear as repeat buyers in the recent record. Representative recent opportunities include Collier County's South County Water Reclamation Facility Preliminary Treatment Screen Replacement (IFB, October 2025, estimated budget $3.21 million) involving installation of Multi-Rake Bar Screens and Wash and Press units; Paulding County Jail Bar Screen installation (ITB, bids due July 31, 2026) covering mechanical bar screen equipment within a precast concrete structure with compactor and slide gates; City of Huntsville's AJ Brown Wastewater Treatment Facility bar screen and auger compactor installation (RFP, bids due April 7, 2026, estimated $375,000); and City of Tampa's procurement of replacement Sweco Vibro-Energy Separator grit remover parts (RFQ, June 2026). Activity concentrates in Florida, Texas, and Georgia, with secondary activity in California and other states. Most procurements are capital equipment installations or major rehabilitation projects; standalone parts and service contracts appear less frequently but signal ongoing maintenance demand at aging facilities.
