UNSPSC 70171506: Ground or surface water modeling services

UNSPSC 70171506 Ground or surface water modeling services (Commodity) encompasses the design, testing, and monitoring of water and wastewater infrastructure—particularly treatment systems, distribution networks, injection wells, and facility control systems—rather than computational hydrology or groundwater flow simulation. State and local governments procure under this code for operational water quality testing, facility-specific instrumentation upgrades, environmental compliance services, and specialized technical support tied to active treatment plants, distribution systems, and regulatory reporting. Recent solicitations show city water departments, county utilities authorities, state correctional facilities, and regional wastewater agencies requesting vendors to perform routine water testing and analysis, design or upgrade SCADA and monitoring systems, conduct mechanical integrity testing of deep injection wells, provide environmental compliance documentation, and supply specialized laboratory services and control equipment for potable and reclaimed water systems.

Activity is concentrated in Florida, Georgia, California, Illinois, and Connecticut, with municipal water departments and utility authorities as the primary buyers. Representative recent work includes the City of Orlando soliciting hydrogen sulfide control services at lift stations (IFB, September 2026); Clackamas County Water Environment Services requesting sealed bids for aeration basin refurbishment including SCADA upgrades (BID 2026-78, due November 10, 2026); Hillsborough County Capital Projects Management requesting bids for a 1500 kW diesel generator installation at the Valrico Reclaimed Water Facility with a 5% SBE goal (IFB2600406, estimated $4.7 million, due November 18, 2026); the Illinois Department of Corrections seeking Class B or higher certified water system operators for routine testing and reporting at correctional facilities (multiple ITBs in June–July 2026); and the City of Phoenix Water Services Department requesting sealed offers for atmospheric monitoring instruments to detect hazardous gases at water and wastewater facilities (IFB-27-0435, five-year term, due September 4, 2026). Most opportunities require active state or federal certifications, compliance with EPA and state environmental regulations, proven experience on comparable projects, and comprehensive insurance including professional liability coverage.
