Based on the results of the past 4 workshops (2 times in Tokyo, 1 time each in Bangkok and Jakarta), this workshop will share the experiences of Asian countries and gain a common understanding of issues and directions that should be addressed in the future. At the same time, the aim is to build a network of stakeholders in each country and strengthen cooperation toward the further promotion of decentralized wastewater treatment in Asia. Proper dissemination of decentralized wastewater treatment systems is expected to contribute to the improvement of public health and the conservation of the water environment in order to achieve targets 6.2 and 6.3 of the UN SDGs on sanitation in Asia.
Representatives from each country talked about regulations and systems related to decentralized wastewater treatment, the operation and management of decentralized wastewater treatment facilities, policies and regulations, examples and issues of administrative efforts, standards and performance evaluation test systems for decentralized wastewater treatment facilities, Successful cases in developing countries and the current status of sludge management were presented.In addition, Kubota johkasou System Co., Ltd. and Daiki Axis Co., Ltd., who are developing his johkasou business in Myanmar, made presentations on the implementation status and challenges of the johkasou business in Myanmar and other developing countries.In the Q&A session after the presentation, many questions and opinions were raised from the floor under the chairman's lead, and we were able to deepen the discussion on the content of the presentation.
In the panel discussion, not only the panelists representing each country, but also many opinions were expressed from the floor, and a lively discussion developed.Finally, a common understanding for promoting decentralized wastewater treatment in Asian countries was compiled and unanimously adopted as a joint declaration of the workshop.
In the future, it is expected that Asian countries will promote decentralized wastewater treatment as an important measure for domestic wastewater treatment in order to solve the problems of decentralized wastewater treatment that were clarified in the Declaration.
The 6th Workshop on Decentralized Wastewater Treatment in Asia will be held in Tokyo in September 2018 in conjunction with the IWA World Congress.
