De Nora wins Johor River UV system refurbishment project

Industrie De Nora will supply Sentinel UV technology for a refurbishment at PUB’s Johor River Waterworks in Singapore, with installation planned for 2027. The project, awarded by Flotech Controls, points to continued demand for retrofit-ready water treatment systems that preserve existing infrastructure while improving reliability and efficiency. Why it matters: - The project supports Singapore’s drinking water supply by refurbishing UV disinfection systems at PUB’s Johor River Waterworks. - The retrofit approach is designed to extend the life of critical water infrastructure without replacing the full system. - The work underscores demand for water treatment upgrades that reduce material use, waste and carbon dioxide emissions. What happened: - Industrie De Nora said it was selected to supply Sentinel® UV technology with upgraded electronic ballast systems for the Johor River Waterworks project. - Flotech Controls, PUB’s appointed contractor, awarded the project. - The UV systems were originally commissioned in 2011. - Installation is scheduled for 2027. The details: - PUB commissioned a tender for replacement or refurbishment as the existing UV systems move into the later stages of their operational lifespan. - Flotech Controls proposed a refurbishment and retrofit approach with De Nora because of space constraints inside the building housing the UV systems. - The project is part of De Nora’s Sentinel® retrofit program. - The retrofit allows reuse of key system components while modernizing system performance. - The upgraded system is expected to deliver extended lamp life and a smaller footprint. - De Nora says the medium pressure UV technology is designed for demanding drinking water applications. - Flotech Controls selected the system for its reliability, ease of maintenance and ability to fit existing infrastructure without full replacement. Between the lines: - PUB’s choice signals a preference for upgrades that improve performance while limiting disruption to existing operations. - De Nora’s local sales and aftersales support in Singapore likely helped strengthen the bid in a market that values serviceability and continuity. - The selection also reflects a broader shift toward retrofit solutions in water utilities that want to preserve installed assets. What’s next: - De Nora and Flotech Controls are moving toward the 2027 installation window. - The refurbished UV systems will be used to support ongoing disinfection at Johor River Waterworks once the upgrade is complete. - The project may serve as another reference for De Nora’s retrofit-focused UV offerings in municipal water treatment.
