Water is a basic need for humans, the environment and the Earth. Governments, engineers and researchers have worked together toward securing water supplies and managing water quality around the world. The International Water Association is one of the biggest international organizations working to achieve such goals.

Tokyo will host the IWA World Water Congress & Exhibition 2018 from Sept. 16 to 21. The event is expected to attract 6,000 people from more than 100 countries to discuss technology, public policies and other subjects to achieve sustainable water management practices.

In preparation for the exhibition, The Japan Times held a forum in Tokyo on June 11 to discuss topics that included what to expect, Tokyo's significance as the host city and what the country can do to help the world.
