UNSPSC 41104203: Base exchange equipment

UNSPSC 41104203 Base exchange equipment is a Commodity code. State and local governments use this code to procure replacement parts, equipment, and services for wastewater and water treatment facilities—particularly specialized mechanical systems, instrumentation, and control devices that are proprietary or manufacturer-specific. Recent solicitations show a consistent pattern of sole-source and single-source procurements driven by system integration requirements, OEM exclusivity, and operational criticality. Water and wastewater authorities procure drive shafts for treatment plant components, valve actuators and control systems, pressure and temperature transmitters, laboratory analyzers, and SCADA equipment under this code. The issuing bodies are primarily county water departments, municipal water utilities, and independent water districts; repeat purchasers include the City of Tampa Water Services, Marion County Utilities (Florida), Collier County Water and Wastewater, and Orange County Utilities (Florida), each pursuing multiple single-source procurements for equipment integration with legacy infrastructure.

Geographic activity concentrates in Florida, Georgia, and California, with recent opportunities posted from Marion County, Collier County, the City of Tampa, the City of Plant City, City of Valdosta (Georgia), Gwinnett County (Georgia), Long Beach Public Utilities (California), and Santa Clara County (California). Representative recent procurements include the City of Holly Hill, Florida sole-source procurement of a WesTech DS43 Dual Shaft Drive replacement and installation services for softener #2 at the Water Treatment Plant (SS202001, notice posted October 19, 2026, responding by September 22, 2020, $113,067.00 total); Marion County, Florida's Notice of Intent (27SS-006, posted October 12, 2026, due October 16, 2026) to procure specialized covert surveillance equipment and camera systems for law enforcement; the City of Tampa's Intent to Single Source Swan Analytical Instruments parts, service, and support for water production operations (26X01275, posted October 5, 2026, due October 2, 2026); and Eastern Municipal Water District's RFP for meter verification, calibration, certification, preventive maintenance, and repair services (RFP3856, posted June 9, 2026, due July 15, 2026, serving Riverside County, California). Sole-source justifications consistently cite OEM exclusivity, SCADA system integration, technical compatibility with existing equipment, and the proprietary nature of replacement components, limiting competition to authorized distributors or the original manufacturer.
