--- title: Ultrapure Water Systems for Semiconductor Manufacturing | Veolia description: Veolia delivers ultrapure water systems for semiconductor manufacturing, ensuring reliability, optimal yield and advanced digital control for the industry's most demanding standards. --- [![Veolia logo](https://campaign.veoliawatertechnologies.co.uk/hubfs/vwt-global/images/header-logo-capsule.png "Veolia logo")](https://www.veoliawatertechnologies.co.uk/) # ULTRAPURE RELIABILITY for Advanced Semiconductor Manufacturing Engineered for purity, reliability and yield. Veolia delivers ultrapure water systems that meet the world’s most demanding semiconductor standards. Ultra pure water (UPW) is used in fabrication plants for removing inorganic salts and organic matters from the wafer surface, the presence of which directly affects the number of chips or devices that can be produced. With 1,500 litres of UPW typically used to wash one silicon wafer, it's safe to say that UPW is the invisible foundation of semiconductor manufacturing. For over forty years, Veolia has engineered, built and operated UPW systems for the world’s most advanced fabs, combining global expertise with precision manufacturing and digital control. Our solutions deliver absolute consistency and uptime, enabling faster production ramps, higher yields and lower total cost of ownership. ## HOW VEOLIA HELPS YOU ACHIEVE UPW RELIABILITY Veolia partners with the world’s leading semiconductor manufacturers to deliver ultrapure water systems engineered for today’s most advanced nodes - and tomorrow’s. Our expertise spans the full UPW lifecycle: from system design and fabrication to commissioning, operation and continuous optimisation. Whether you’re building a new fab or upgrading an existing facility, we deliver repeatable purity, digital control and long-term reliability across every drop. ## OUR EXPERTISE AT A GLANCE ### ![1-Dec-03-2025-10-15-22-3654-AM](https://campaign.veoliawatertechnologies.co.uk/hs-fs/hubfs/1-Dec-03-2025-10-15-22-3654-AM.png?width=348&height=232&name=1-Dec-03-2025-10-15-22-3654-AM.png)[UPW SYSTEM DESIGN](https://campaign.veoliawatertechnologies.co.uk/en-gb/microelectronics-upw-system-design?hsLang=en-gb) Modular, scalable systems engineered for next-generation semiconductor fabs.         * Learn more. * ### ![2-Dec-03-2025-10-15-22-3803-AM](https://campaign.veoliawatertechnologies.co.uk/hs-fs/hubfs/2-Dec-03-2025-10-15-22-3803-AM.png?width=348&height=232&name=2-Dec-03-2025-10-15-22-3803-AM.png)[TECHNOLOGY & PERFORMANCE](https://campaign.veoliawatertechnologies.co.uk/en-gb/ultrapure-water-technology-performance-for-microe?hsLang=en-gb) Advanced RO, EDI, and polishing systems delivering \<500 ppt TOC and \>18 MΩ·cm resistivity. *Lea**rn more. * ### ![3-Dec-03-2025-10-15-22-4266-AM](https://campaign.veoliawatertechnologies.co.uk/hs-fs/hubfs/3-Dec-03-2025-10-15-22-4266-AM.png?width=348&height=232&name=3-Dec-03-2025-10-15-22-4266-AM.png)[PRECISION MANUFACTURING](https://campaign.veoliawatertechnologies.co.uk/en-gb/microelectronics-upw-precision-manufacturing?hsLang=en-gb) ISO 9001-certified cleanroom fabrication for consistent, contamination-free builds. * Learn more.* ### ![4-Dec-03-2025-10-15-22-3157-AM](https://campaign.veoliawatertechnologies.co.uk/hs-fs/hubfs/4-Dec-03-2025-10-15-22-3157-AM.png?width=348&height=232&name=4-Dec-03-2025-10-15-22-3157-AM.png)[DIGITAL CONTROL & MONITORING](https://campaign.veoliawatertechnologies.co.uk/en-gb/microelectronics-ultrapure-water-digital-control-monitoring?hsLang=en-gb) Protect your yield by anticipating process deviations before they impact production.
