UNSPSC 47101516: Turbidimeters

UNSPSC 47101516 Turbidimeters, a Commodity code, spans water quality monitoring instruments that state and local water utilities, treatment facilities, and environmental agencies procure to measure cloudiness and particle suspension in drinking water, wastewater, and surface water systems. Recent solicitations show turbidimeters are typically purchased as single units or small quantities to replace aging equipment or support compliance with EPA and state water quality standards, often bundled with controllers, analyzers, and multiparameter sondes that monitor chlorine, pH, temperature, conductivity, and dissolved oxygen in real time across treatment plants and distribution networks.

Water utilities dominate the issuing body mix: municipal water departments and county water resources divisions in Florida, Texas, Arizona, Georgia, and California have posted the most recent activity. The City of Tampa, Hillsborough County, and the Texas Commission on Environmental Quality appear repeatedly in recent opportunities. Solicitations range from single-source procurements for replacement equipment to open competitive bids for new monitoring systems. Representative recent opportunities include the City of Tampa's Intent to Single Source for Wallace and Tiernan analyzers to monitor chlorine, pH, and temperature at the David L. Tippin Water Treatment Facility (estimated annual cost $75,000, comment period closed July 16, 2026); the Texas Commission on Environmental Quality's IFB for YSI EXO multiparameter sondes and conductivity sensors (bids due July 17, 2026, anticipated contract value under $90,000); and the City of Tampa's RFQ for a Surface Scatter 7sc Turbidimeter with SC4500 Controller (quotes due June 1, 2026). Sole-source and single-vendor procurements are common because water agencies standardize on manufacturer-specific equipment for spare parts, service interoperability, and regulatory compliance, creating switching costs that lock in incumbent vendors. Florida and Texas show the strongest recent activity, with additional opportunities in Arizona, Georgia, and California. Geographic concentration reflects sunbelt population growth and heightened regulatory scrutiny of drinking water quality, particularly for PFAS and algae-related contamination in states managing rapid urban expansion.
