UNSPSC 32151502: Light module

UNSPSC 32151502 Light module is a Commodity code that encompasses control system components and integrated automation equipment installed as part of water treatment plant modernization projects, including operator interface terminals, programmable logic controllers, and related supervisory control and data acquisition upgrades. State and local governments procure these products primarily through water utilities and municipal departments of watershed management seeking to replace aging industrial control infrastructure. The products are typically purchased as components of larger system integration contracts that bundle equipment supply with engineering design, installation labor, Factory Acceptance Testing, and operator training. Issuing bodies include city departments of watershed management and municipal water authorities managing treatment plant operations.

Recent activity concentrates in Georgia and California, with representative opportunities including the City of Atlanta's Hemphill Water Treatment Plant SCADA Improvement (RFP posted May 8, 2026, due May 29, 2026) and Chattahoochee Water Treatment Plant SCADA Improvement (pre-advertisement notice, same dates), both soliciting comprehensive modernization replacing General Electric iFix systems with Schneider Electric AVEVA Wonderware HMI systems and upgrading to Allen-Bradley ControlLogix controllers and PanelView Plus 7 operator interface terminals. The Eastern Municipal Water District in Riverside County, California issued RFB #3921 (posted March 26, 2026, due April 30, 2026) procuring three 500-horsepower Variable Frequency Drives in NEMA 1 enclosures for the Palomar Booster facility. The City of Santa Fe on behalf of Buckman Direct Diversion issued RFP FY26-RFP-036 (posted February 9, 2026) for PLC replacement and SCADA modifications involving Schneider Electric Unity Pro XL software and M580 PLC replacements across 13 water system sites. These opportunities are part of municipal infrastructure modernization cycles driven by aging control system hardware and the shift toward standardized, Ethernet-based industrial automation platforms.
