REDEFINING UPW SYSTEMS FOR MICROE

ENGINEERED FOR PRECISION. BUILT FOR PURITY.

For today’s advanced fabs, UPW functions as both a fundamental utility and a key performance driver. Veolia’s UPW system designs are the result of over forty years of engineering evolution, delivering absolute consistency, efficiency and control across every drop. Our modular, digitally integrated approach ensures fast ramp-up, simplified operation and reproducible purity that keeps pace with next-generation semiconductor manufacturing.

 Our Design Philosophy | 
 Built for Advanced Node Performance 

Every Veolia UPW system is engineered around one objective: to achieve the most stable and repeatable water quality possible for today’s advanced node manufacturing environments.
We design for:

  • Stability: Continuous compliance with resistivity, TOC and particle specifications under varying load.
  • Efficiency: High recovery and minimal chemical use through advanced RO and EDI configurations.
  • Reliability: Proven uptime and performance repeatability, enabling faster fab ramp and sustained yield.

Our design principles integrate process resilience, digital monitoring, and future scalability, ensuring your UPW system remains production-ready for every node transition.

CAPABILITIES | UPW FABRICATION & ASSEMBLY

Veolia’s UPW systems are built in controlled cleanroom environments to ensure contamination-free assembly and long-term performance. Our facilities combine precision manufacturing with rigorous quality control to guarantee that each skid, vessel, and valve performs to semiconductor-grade standards.

  • 3 UPW fabrication facilities

  • 152,000 ft² total constructed area

  • 45,000 ft² Class 100,000 cleanroom area (Guelph, Ontario)

  • 1,000 Cleanroom Classification for PVDF & PP piping

  • 10,000 Cleanroom Classification for staging and material handling

  • ISO 9001 Quality Management System

  • Fabrication methods aligned with SEMI and ASTM standards

    Each assembly undergoes hydrostatic testing, leak detection and full instrumentation verification prior to shipment,  ensuring plug-and-play commissioning on site.
