2018/10/11 6th Workshop on Decentralized Domestic Wastewater Treatment in Asia was held in Tokyo

The 6th Workshop on Decetralized Domestic Wastewater Treatment in Asia was held in Tokyo

 

 

On 19th September, 2018, "The 6th Workshop on Decentralized Domestic Wastewater Treatment in Asia"

hosted by the Ministry of the Environment of Japan was held in Tokyo, Japan. There were many attendances

from participants of the IWA World Water Congress & Exhibition 2018, which was held at the same period.

 

Based on the results of the workshop held five times in the past (two times in Tokyo, one time in Bangkok,

one time in Jakarta, and one time in Yangon). This workshop shares the experiences of Asian countries and

gains common recognition about issues and directions to be addressed in the future. Towards further promotion

of decentralized domestic wastewater treatment in Asia, we aim to build networks and strengthen cooperation

among stakeholders in each country. In September 2015, the United Nations' SDGs (sustainable development goal)

was adopted, and in the sanitation field, a target of 6.3 "By 2030, improve water quality by reducing pollution,

eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of

untreated wastewater and substantially increasing recycling and safe reuse globally " was set up. Looking ahead,

in order to attain this SDGs, it is expected that the decentralized wastewater treatment will further accelerate

in Asian countries.

 

In this workshop, there were around 100 participants in total, including about 50 participants from Japan

(of which 5 presenters) and 50 participants from overseas countries (of which 7 presenters). Regarding to the

participant from Japan, it is included the Ministry of the Environment, JICA, Japan Sanitation Association,

and Johkasou System Association and several construction consultancy companies.

 

In the opening ceremony, Mr. Takayuki Matsuda, director of Office for Promotion of Johkasou,

the Ministry of the Environment of Japan gave an opening address as an organizer. The main goals of this workshop

and the willingness every participant shall get fruitful success were mentioned in his speech.

 

Representatives from Asian countries introduced “Current Situation and National Policies Regarding to

Domestic Wastewater” in the morning session. In the afternoon session, “O & M, and Human Resource

Development” and “Performance Evaluation Test” were set as the discussion themes. Under the leadership

of the Chairs, we had lively discussion. And there are many participants related to the IWA World Water

Congress & Exhibition 2018, this should suggest the high interest on the decentralized wastewater treatment.

 

In conclusion, each Chairs (Dr. Kawamura, Mr. Hashimoto, Dr. Ebie, Dr. Kumokawa) reviewed and summarized

their sessions, and the workshop had closed. In the end, there was a remark from Dr. Yang Min from Research

Center for Eco-Environmental Sciences, Chinese Academy of Science Chinese that opportunity for networking

is important, to hold workshop continuously in the future are expected. And more, Dr. Viet Anh Nguyen,

presenter from Vietnam proposed to hold the next workshop in Vietnam to promote the decentralized wastewater

treatment in Vietnam.

 

The next "Workshop on Decentralized Domestic Wastewater Treatment in Asia" is planned to be held in Vietnam.
