Purpose of the Exhibition

The Sewage Works Exhibition is Japan’s largest annual exhibition on the theme of sewage systems. It is held for local governments and other entities that manage the business of sewage systems to exhibit the latest technology and equipment developed by Japanese companies and organizations involved in the wide range of fields related to sewage systems. It is also held for the general public to encourage understanding and inspire interest in sewage systems.
The water business is undergoing worldwide change, as illustrated by increased calls for the development and popularization of globally competitive technologies. Amid such changes, the Sewage Works Exhibition seeks to help create a global brand for Japanese sewage systems by working proactively to attract visitors and exhibitors from around the world.
The exhibition provides many different offerings, including exhibitor presentations, which are opportunities for companies and organizations to introduce their technologies and equipment; concurrent projects such as technical tours for showing people the equipment and machinery of wastewater facilities; and exhibitions and events for the general public.
