UNSPSC 32151901: Bulkhead pass through connector

UNSPSC 32151901 Bulkhead pass through connector is a Commodity code that, based on recent state and local solicitations, encompasses industrial control system components and related automation equipment — particularly programmable logic controllers, SCADA system replacements, valve positioners, and continuous emissions monitoring equipment used in water treatment, energy generation, and municipal infrastructure facilities. State and local governments procuring under this code include municipal water districts, city departments of watershed management, independent school districts, county governments, and city purchasing offices. The City of Austin Purchasing Office and the City of Atlanta Department of Watershed Management appear repeatedly in recent solicitations, reflecting sustained capital investment in water treatment plant modernization and energy facility upgrades.

Recent activity spans multiple states with particular concentration in Texas and Georgia. The City of Austin has posted two quotation requests for valve positioners and emissions monitoring equipment (IFQ1100AGM1029 for a digital valve positioner due October 20, 2026, and IFQ1100BAS1098 for a Woodward positioner valve due August 5, 2026). West Basin Municipal Water District in California issued an RFP for Torrance Refinery Water Recycling Plant Programmable Logic Controller Replacements due November 5, 2026, involving Modicon M580 processor installations and SCADA system integration. The City of Atlanta issued back-to-back solicitations in fall 2026 for SCADA improvements at its Chattahoochee and Hemphill water treatment plants (both due October 14, 2026), calling for Schneider Electric controller replacements and comprehensive system modernization. The City of Santa Fe, New Mexico, solicited PLC replacement and SCADA modifications for the Buckman Direct Diversion water system via RFP FY26RFP036. Northside Independent School District in San Antonio consolidated athletic equipment and related services procurement under IFB2026137 due October 19, 2026, though this solicitation appears tangential to the code's industrial controls focus and does not represent typical activity under the commodity.
