UNSPSC 32151906: Control system splitter

UNSPSC 32151906 Control system splitter, a Commodity code, describes network infrastructure and control signal distribution components deployed in industrial automation and water/wastewater treatment facilities. State and local governments procure these splitters as part of larger SCADA modernization and process control system upgrades that replace obsolete programmable logic controller (PLC) networks with contemporary Ethernet/IP and fiber-optic architectures. The solicitations under this code reflect demand from municipal water utilities and transit authorities executing comprehensive system replacements—typically involving migration from legacy ControlNet or proprietary networks to IP-based infrastructure with distributed intelligence across multiple process areas. Issuing bodies are dominated by municipal water authorities and treatment plant operators, with the City of Atlanta Department of Watershed Management appearing twice in recent activity (Hemphill and Chattahoochee water treatment plants), alongside specialized-purpose entities such as the Eastern Municipal Water District in California and city-sponsored authorities managing critical infrastructure. These buyers procure splitters as components within engineering procurement and installation (EPI) or turnkey integration contracts that bundle equipment supply, labor, testing, and training.

Geographic activity clusters in the Southeast and West, particularly Georgia and California. Recent representative opportunities include the City of Atlanta's May 2026 pre-advertisement notice for SCADA improvements at the Hemphill Water Treatment Plant (PE66062NONST2026000000376, RFP with May 29, 2026 response date), which specifies conversion of ControlNet networks to Ethernet/IP architecture with new 5580 ControlLogix controllers and comprehensive system modernization across 16 filter consoles; the City of Atlanta's parallel solicitation for Chattahoochee Water Treatment Plant upgrades (PE66062NONST2026000000374, May 29, 2026 deadline), involving similar network conversion and multi-building integration; and the City of Santa Fe's February 2026 PLC replacement and SCADA modification RFP (FY26-RFP-036) for the Buckman Direct Diversion, requiring Schneider Electric M580 controller deployment across 13 water system sites. These procurements typically mandate qualified prime contractors with five or more years of comparable end-to-end SCADA integration experience, specific PLC and HMI platform certifications (Allen-Bradley ControlLogix, AVEVA Wonderware), and documented past performance on water treatment facility upgrades. Splitters are rarely solicited as standalone commodity line items; they enter procurement as specified components within larger system architecture contracts where control signal distribution and network segmentation are engineered as part of site design and integration planning.
