UNSPSC 32152002: Supervisory control and data acquisition packaged system SCADA

A process control system that collects data from sensors and or machines and sends them to a central computer for management and control. Common components include human to machine interface HMI, remote terminal unit RTU and programmable logic controller PLC.

UNSPSC 32152002 Supervisory control and data acquisition packaged system SCADA, a Commodity code, covers the procurement of SCADA systems and related control components—typically PLC replacements, HMI upgrades, network modernization, and integration services—used by state and local water utilities, wastewater treatment authorities, and municipal energy facilities to monitor and automate critical infrastructure. State and local governments acquire integrated SCADA packages to replace aging control architectures, modernize process monitoring across multi-facility networks, and maintain operational reliability in active treatment plants and water distribution systems. Issuing bodies include municipal water districts (West Basin Municipal Water District), city departments of watershed management and utilities (City of Atlanta, City of Austin, City of Santa Fe), county and regional water authorities (Salt Lake City Corporation), wastewater treatment operators (Maryland Environmental Service, Dorsey Run facility), and independent school districts (though school-district activity under this code appears to be a mislabeled opportunity unrelated to SCADA systems).

Recent solicitations reflect a strong concentration in water treatment plant modernization across the South and Southwest. The City of Atlanta has posted two substantial SCADA upgrade RFPs—for Hemphill and Chattahoochee water treatment plants (both due October 14, 2026 / September 30 posting, with earlier pre-advertisement notices in May 2026)—requiring end-to-end PLC and HMI replacement with Schneider Electric AVEVA Wonderware platforms, 360-day project timelines, and Factory and Site Acceptance Testing. West Basin Municipal Water District (Torrance, California) is seeking RFP responses for PLC replacements at the Torrance Regional Water Recycling Plant (due November 5, 2026), including reverse osmosis and biofilm SCADA recommissioning using Modicon M580 processors and integration with an existing Emerson Ovation DCS system. Salt Lake City Corporation issued an RFP for five-year on-call SCADA and telemetry consulting services across four water treatment plants and multiple distribution systems (RFP SLCI26095, closed June 26, 2026), with emphasis on Ignition and Wonderware platforms and Modicon / Allen-Bradley PLC support. The City of Santa Fe is seeking PLC replacement and SCADA modifications for Buckman Direct Diversion water treatment (RFP FY26-RFP-036, with proposals due January 9, 2026, though this date appears to conflict with the posting of August 17, 2026). Maryland Environmental Service issued an IFB for replacement of a lime system PLC and related controls at Dorsey Run Wastewater Treatment Plant (due November 6, 2026) with a 20 percent MBE participation requirement. Activity is concentrated in Georgia (City of Atlanta), California (West Basin), Utah (Salt Lake City), Texas (City of Santa Fe, City of Austin), and Maryland (Dorsey Run), with municipal water and wastewater utilities dominating the buyer base.
