From science to practice and policy

Tokyo was an excellent venue for the 2018 IWA WWC, and the congress was a catalyst for progressing towards a water-wise world.

Solving together the problems common to all megacities, Tokyo was the platform upon which the know-how and knowledge of the IWA colleagues was exchanged and deliberated in 2018. As a gateway to Asia and the world, Tokyo also provides attractive business opportunities to all the participants.

The IWA World Water Congress & Exhibition is the global event for water professionals covering the entire water cycle. As the Congress rotates through cities and countries each event has an extra emphasis on issues of specific interest to the region. The 2018 edition took place in Tokyo and had as key focus the digital economy, megacities, diffusion of innovation, disaster resilience and sustainability. Check the  programme online.

Japan has proactively and continually shared the experiences and know-how with other countries. Keeping this tradition the country would like to share water-wise best practices and technologies. Japan’s Quality, Japan’s Experience – Stability & Resilience

Tokyo Expertise in Water Management

Tokyo has strong relationships with many countries around the world, especially with neighbour countries in Asia. This network has been mutually nurtured over the years and has the capability to effectively attract large numbers of water professionals from all over the world to Tokyo.

Water supply and sanitation in Japan is characterized by numerous achievements and some challenges. The country has achieved universal access to water supply and sanitation; has one of the lowest levels of water distribution losses in the world; regularly exceeds its own strict standards for the quality of drinking water and treated waste water; uses an effective national system of performance benchmarking for water and sanitation utilities; makes extensive use of both advanced and appropriate technologies such as the jōkasō on-site sanitation system; and has pioneered the payment for ecosystem services before the term was even coined internationally.

The global event for water professionals.

The IWA World Water Congress & Exhibition brought together 9815 water, environment and related professionals from more than 100 countries and offers new insights into how pioneering science, technological innovation and leading practices shape the major transformation in water management that is underway.
