UNSPSC 32152000: Process control or packaged automation systems

Complete packaged systems that automate control of a process and typically deal with analog signals from sensors and meters that are transmitted to specialized computers which cause the temperature, pressure and flow to be continually adjusted. Process control makes extensive use of analog to digital and digital to analog conversion.

UNSPSC 32152000 Process control or packaged automation systems (Class) encompasses SCADA system upgrades, HMI replacements, PLC modernization, control panel retrofits, and related industrial automation services that state and local governments procure to maintain and modernize water treatment plants, municipal utilities, and facility infrastructure. Water treatment plant SCADA modernization dominates current activity, with municipalities replacing aging General Electric iFix and legacy Quantum PLC systems with modern platforms such as AVEVA Wonderware, Schneider Electric architectures, and Allen-Bradley ControlLogix controllers. State departments, municipalities, and special-purpose water districts are the primary issuing bodies. The City of Atlanta Department of Watershed Management is the most active recent buyer, with two parallel SCADA upgrade procurements issued in May 2026 for the Hemphill and Chattahoochee Water Treatment Plants, both seeking comprehensive system replacements involving network architecture conversions, HMI deployment, Factory Acceptance Testing, operator training, and as-built documentation. The California Department of Veterans Affairs and City of Santa Fe have posted SCADA maintenance and PLC replacement work. Vendors must demonstrate five years of comparable integration experience, documented past performance on similar water or wastewater treatment projects, and qualified project managers and controls engineers with specific platform expertise (ControlLogix, AVEVA, Schneider Electric Unity Pro).

Recent opportunities cluster in Georgia, California, and New Mexico, with secondary activity in Florida. The City of Atlanta's Hemphill Water Treatment Plant SCADA Improvement (PE66062NONST2026000000376, pre-advertisement notice posted May 8, 2026, response deadline May 29, 2026) and Chattahoochee Water Treatment Plant SCADA Improvement (PE66062NONST2026000000374, same dates) represent the largest and most actively solicited work. Both procurements follow a 360-day project timeline with comprehensive scope spanning equipment procurement, network upgrades, Factory Acceptance Testing with four days of on-site validation, five consecutive days of operational testing, and three training sessions. The California Department of Veterans Affairs issued a quote solicitation for SCADA Maintenance Services at the Veterans Home in Yountville (0000038400, due April 2, 2026) limited to certified California Small Businesses and Micro Businesses, with a fixed quarterly maintenance rate of $10,000.00 and emergency repair add-ons. The City of Santa Fe posted RFP FY26-RFP-036 for PLC Replacement and SCADA modifications to the Buckman Direct Diversion system (due December 18, 2025), requiring Schneider Electric Unity Pro programming and seasonal installation windows October through March.
