UNSPSC 47101507: Grit chambers

UNSPSC 47101507 Grit chambers (Commodity) encompasses water treatment equipment components and related maintenance services, though the recent solicitation activity shows state and local governments buying substantially different products under this code—primarily reverse osmosis membranes, deionized water systems, filtration equipment, treatment chemicals, and blower parts rather than grit chambers themselves. The issuing bodies span state universities, county water departments, municipal water treatment facilities, and regional water districts. Florida counties (Hillsborough, Collier) and Georgia municipalities (Atlanta, Gwinnett County, LaGrange) appear frequently, alongside Texas cities (Fort Worth, LaGrange) and California water districts (West Basin).

Recent representative opportunities include Texas State University's RFP for reverse osmosis and deionized water systems maintenance and services (response due August 10, 2026); Collier County's sealed-bid procurement for SCRWTP lime softening improvements including a blend tank, chemical injection systems, and instrumentation (bids due July 1, 2026 at $3.29 million); West Basin Municipal Water District's RFQ for submerged microfiltration membranes for the Edward C. Little Water Recycling Facility (SOQs due May 26, 2026); and the City of Atlanta Department of Watershed Management's multi-step sealed-bid prequalification for Howden Turblex blower parts, repair services, and ancillary support across four equipment groups at municipal facilities (prequalification due July 31, 2026). Sole source procurements dominate the activity, with Hillsborough County awarding to Thomas Water Purification LLC for deionized water systems ($76,530 over two years), Collier County to Alfa Laval for a lime sludge dewatering belt filter press (contract term October 1, 2026 through September 30, 2029), and Hillsborough County to Fluid Control Specialties, LLC for advanced treatment parts and services ($1,458,835 over five-plus years). The code shows active procurement for water treatment infrastructure maintenance and component replacement, with emphasis on equipment compatibility, manufacturer certification, and regulatory compliance for drinking water and wastewater systems.
