UNSPSC 41104207: Water analysis systems

UNSPSC 41104207 Water analysis systems, a Commodity code, encompasses analytical equipment, replacement parts, consumable supplies, and related instrumentation that state and local water and wastewater utilities deploy to monitor water quality, process control, and regulatory compliance. Recent opportunities show governments buying chlorine analyzers, turbidity meters, pH sensors and probes, pressure and temperature transmitters, level controllers, valve positioners, flow meters, specialized equipment for detecting hydrogen sulfide and other hazardous gases, calibration materials, and proprietary analyzer systems from manufacturers including Hach, Swan Analytical Instruments, Wallace and Tiernan (Evoqua), Siemens Process Instrumentation, In-Situ pressure transducers, and Digital Watchdog surveillance systems. Issuing bodies are predominantly municipal water departments and regional water authorities, with participation from county utilities and wastewater treatment facilities. Sole-source and single-source procurements dominate the recent activity, reflecting the proprietary nature of much equipment and the technical lock-in created by existing infrastructure integration; competitive open solicitations for water meter systems and calibration services appear occasionally but represent a smaller share of posted activity.

Florida municipalities and regional authorities account for the heaviest concentration of recent solicitations—notably Tampa (multiple single-source notices for Siemens, Wallace and Tiernan, Swan Analytical, Bernard, Beck, and Limitorque products), Tampa Bay Water, the City of Valdosta Georgia, and Marion County utilities. Representative recent opportunities include Tampa Bay Water's notice of intent to sole-source Evoqua/Wallace and Tiernan analytical equipment and consumables from Water Treatment & Controls Technology, Inc. (objection period ending October 27, 2026); the City of Tampa's intent to single-source Swan Analytical Instruments parts, service, and support (response deadline passed, but posted October 5, 2026); Marion County Board of Commissioners' sole-source notice for chlorine analyzers, NTU meters, and pH sensors (posted September 23, 2026, five-day public-comment window); and Eastern Municipal Water District's RFP for meter verification, calibration, certification, preventative maintenance, and repair services in Riverside County (proposals due July 15, 2026). The Purchasing Cooperative of America is also soliciting water meter systems and related items under RFP OD-450-26, available to PCA members nationally and statewide (proposals due October 27, 2026). Geographic spread spans Florida, Georgia, California, and multi-state cooperative arrangements, with sole-source activity the dominant procurement pattern reflecting vendor exclusivity and equipment compatibility constraints.
