UNSPSC 31250000: Pneumatic and hydraulic and electric control systems

UNSPSC 31250000 Pneumatic and hydraulic and electric control systems is a Family code that encompasses water treatment automation components, measurement instrumentation, valve actuation equipment, and related control infrastructure that state and local water and wastewater utilities deploy across treatment plants, distribution networks, and lift stations. Recent solicitations show state and local buyers acquiring control panels with programmable logic controllers and proprietary transducers, submersible pump control systems, electromagnetic flow meters, multi-turn valve actuators, pressure regulators and analyzer assemblies, variable frequency drives for pump motors, and integrated instrumentation packages for water quality monitoring and system automation. Counties, cities, and water authorities—particularly in Florida, Texas, and California—are the primary issuing bodies, with Hillsborough County and the City of Dallas appearing repeatedly as active buyers; water and wastewater utilities dominate procurements, alongside a smaller number of regional water supply facilities and municipal treatment plants.

Recent activity centers on equipment replacement and infrastructure upgrades at operating treatment facilities. Hillsborough County's sole-source procurement for Neptune AMI water meters and associated control infrastructure (estimated $58.4 million over three years, challenge deadline June 29, 2026) represents the largest identified opportunity; additional significant procurements include Orange County, Florida's Eastern Regional Water Supply Facility ground storage tank and variable frequency drive improvements (estimated $11 million, bids due June 9, 2026) and Collier County's lime softening improvements blend tank construction with integrated chemical injection control systems and instrumentation (estimated $3.29 million, bids due July 1, 2026). Smaller component and equipment purchases appear regularly in Dallas, including cartridge split mechanical seals, universal input panel meters, and filter pad assemblies (multiple IFBs with due dates in June and July 2026). Hillsborough County also solicited centrifuge mobile sludge dewatering unit equipment rental ($6.6 million over five years, bids due July 27, 2026) and sole-source procurements for proprietary system support—Heartland Concentrator System operational and technical services ($228,000, one year, challenge deadline July 2, 2026) and Wallace & Tiernan controllers and Depolox analyzer maintenance ($611,692 over five years, challenge deadline May 8, 2026). Activity is highest in Florida and Texas; California and Georgia show smaller procurement volume. The code shows active, ongoing buying centered on water infrastructure automation, system compatibility lock-in, and proprietary equipment support across mid-sized and large municipal utilities.
