Solving Diversified Water Infrastructure Issues

The needs for water infrastructure are becoming more and more diverse, including the repair and improvement of aging facilities in developed countries, the improvement of the quality of sewage treatment and the expansion of treatment capacity in response to urbanization in emerging countries, the development of water supply, sewage disposal, and decentralized treatment facilities in developing countries, and seawater desalination in island nations. JGC Global is committed toJGC Global is not only involved in the development of these diverse water infrastructures, but also offers proposals that contribute to reducing the environmental impact of water infrastructure development, such as reusing water and eliminating wastewater.Translated with www.DeepL.com/Translator (free version)

Why JGC?

  1. 1.We propose water infrastructure business plans from a comprehensive perspective. We propose water infrastructure plans that meet the needs of the community and the customer from an integrated perspective that includes business planning, design, construction, and maintenance management.

    ⟨Business alliance with Nissui-Con⟩

    In April 2021, JGC Global signed a business alliance agreement in the field of water infrastructure with Nissui-Con Corporation, a consultant company specializing in water. Through synergies between JGC Global's engineering and project management capabilities and JGC Global's solution technologies for reducing environmental impact and JGC Global's extensive technical expertise in water infrastructure, JGC Global aims to realize water infrastructure that is both environmentally compatible and economically viable.Translated with www.DeepL.com/Translator (free version)
