Stegra has entered a corporate Private to Private Partnership (PtPP) with John Laing and Aquatech to design, build, finance, operate and maintain a new water treatment facility at Stegra’s industrial site in Boden, northern Sweden.

The comprehensive solution includes treatments for ultra-pure water, wastewater recycling, zero liquid discharge, compact strip production mill scale, and water for cooling systems, ensuring a holistic water management system for the steel plant. The water treatment plant will supply demineralized water to the electrolyzers used to create green hydrogen and purified water used in system cooling, as well as treating wastewater from the steel mill, returning 99.9% of the process water back to the system.

John Laing is an international investor and active manager of core infrastructure assets and Aquatech is a leading provider of zero-liquid discharge water treatment services. John Laing is making a long-term investment in the facility and led the structuring of a water treatment services agreement. The design and build of the water treatment plant equipment and its operation is undertaken by Aquatech under a 25-year services contract. The water treatment plant production is planned to start in 2026.
