"The #2 Workshop on Decentralized Wastewater Treatment in Asia" was held

On 2014/12/1 (Mon) to 2 (Tues), for 2 days, The 2nd Workshop on Decentralized Sewage Treatment in Asia, jointly hosted by the Ministry of the Environment and the Ministry of Natural Resources and Environment, Kingdom of Thailand, was held in Bangkok, Thailand.

Based on the results of the first workshop held in Tokyo in 2013/11, this workshop aims to support the achievement of the MDGs goals related to sanitation in Asian countries and to develop a decentralized wastewater treatment system that contributes to water environment conservation. In order to solve the problems related to the proper dissemination of wastewater treatment, discussions focused on 2 important themes: 1. The role of decentralized wastewater treatment in the dissemination of wastewater treatment, 2. Systems and standards related to decentralized wastewater treatment. The purpose is to share the experiences of each country, gain a common understanding of the issues and directions that should be addressed in the future, and aim to build networks and strengthen cooperation with relevant parties in each country for the promotion of decentralized wastewater treatment in Asia.

This workshop was held as a side event of the International Water Association (IWA) "1st Expert Meeting on Water Management and Sanitation in Developing Countries" and held at the Asian Institute of Technology (AIT).

From overseas and Thailand, 35 Thai environmental administrators, 5 overseas experts from outside Thailand, and 5 local johkasou manufacturers, etc.; from Japan, the Ministry of the Environment and the Japan Sanitation Consortium (JSC), johkasou System Association, and 15 other stakeholders; and about 20 other participants from the IWA plenary session, totaling more than 80 people attended.

On the 1st (Monday), a tour of the johkasou manufacturing factory and johkasou facility was conducted. In the morning, the 35 participants of the workshop visited the Ayutthaya factory of Aqua Nishihara Co., Ltd., a Japanese johkasou manufacturer, and observed the manufacturing process of johkasou. In the afternoon, they moved to the Environmental Research and Training Center (ERTC) of the Ministry of Natural Resources and Environment and visited the johkasou facility and artificial wetland facility. In the evening, a reception was held by the Ministry of the Environment and the Ministry of Natural Resources and Environment, Thailand.

The workshop on the 2nd (Tuesday) was held at the International Conference Hall of AIT and consisted of three sessions: the current status and issues of decentralized wastewater treatment, the case study of johkasou, and the regulations and standards of decentralized wastewater treatment. Done.After that, panelists held a discussion session on the theme of "Promoting Decentralized Wastewater Treatment in Asia".

At the workshop venue, many questions and comments were exchanged between the participants and presenters regarding the content of the presentations, and lively discussions were held on the current status and challenges of on-site wastewater treatment in each country.

The workshop ended with the unanimous adoption of a declaration on the future promotion of on-site processing and improvement of sanitary conditions in Asia.

Through this workshop, the current status and issues of on-site sewage treatment in Asian countries became clearer, and as a new movement, each country agreed to discuss a common performance evaluation system. A trend was formed to develop discussions on professional and practical themes.In the future, it is hoped that each country will share information on on-site sewage treatment and promote on-site sewage treatment in Asia through close cooperation in order to improve sanitation and conserve the water environment in Asia.
