UNSPSC 31250000: Pneumatic and hydraulic and electric control systems

UNSPSC 31250000 Pneumatic and hydraulic and electric control systems is a Family code encompassing the procurement of electric valve actuators, flow meters, control panels, and related instrumentation that state and local governments deploy across water and wastewater infrastructure. Recent solicitations reveal concentrated activity in submersible pump controls, electromagnetic flow meter transmitters, pressure and temperature instrumentation, and replacement actuators for treatment plants and lift stations. Water utilities are the primary issuing bodies, including city water and wastewater departments, county water authorities, and regional treatment authorities. Cities of Fort Worth, St. Petersburg, Phoenix, Santa Monica, and Thousand Oaks; Hillsborough County and other Florida and California jurisdictions; and Great Lakes Water Authority dominate recent activity. The code captures both one-time equipment procurements and call-out maintenance agreements structured as indefinite-quantity contracts with firm pricing or on-call service arrangements.

Water and wastewater treatment plants account for the largest share of solicitations under this code. Recent opportunities include the City of Fort Worth Water Department's RFP for submersible pump service and repair on an as-needed basis with proposals due November 5, 2026; the City of St. Petersburg's sole-source procurement for a Flowserve Limitorque electric valve actuator for the North East Water Reclamation Facility with proposals due August 11, 2026; the City of Phoenix's five-year IFB for pressure and temperature instrumentation equipment with offers due August 18, 2026; and the City of Santa Monica's ITB for laboratory analysis of water, wastewater, and stormwater samples with bids due October 21, 2026. Geographic activity spans Texas, Florida, California, Arizona, Michigan, and Georgia, with Florida and California generating the most recent volume. Set-asides and preferences vary by jurisdiction; some solicitations apply DBE-N compliance (Phoenix, City of Tallahassee) or local-vendor preference (Henry County, Georgia), while others are open competitive or sole-source procurements tied to proprietary equipment already installed in operating systems. Most state and local buyers structure awards to the lowest responsive, responsible bidder and impose prevailing wage, insurance, and regulatory compliance requirements specific to drinking water or wastewater permitting.
