The adoption of the “Project on establishment of the sustainable community network to enhance self-supporting environmental improvement focusing on a community river in south Jakarta area” was accepted by JICA Grassroots Technical Cooperation Projects (special program). Nagasaki City is to become the project’s autonomous proposing municipality, while Nagasaki University (project manager Prof. Takashi Hayase, Graduate School of Fisheries and Environmental Sciences), Nagasaki Institute of Applied Science, Prefectural University of Kumamoto, and Nagasaki Eco-Net are to act as the implementation agencies. This project took over the “Project on the Establishment of Community Network for Sustainable Development through Environmental Activities at a Model Primary School,” which began in 2010 and continued for three years.

In the previous project, we approached municipalities around elementary schools and conducted community network development and educational activities for sustainable development. Through discussions on environmental improvement with residents, a river pollution issue caused by waste and raw sewage was raised, and cleaning and awareness activities by residents began. However, after a short while, some people started to lose hope and say that “no matter how much we work, the river will never be clean.” Observing from a bridge, we found that there were many things flowing in the river. Therefore, at the end of the project, we installed a methane fermentation toilet which prevented raw sewage flow and could also remove methane gas (energy).

For this project, as a short-term improvement to the environment, we set up 10 toilets with special methane handling functions to help reduce the amount of waste flowing directly into the river while also reducing overall pollution in the area. In addition, we hope to introduce water-basin management techniques, and create supportive relationships with communities up and downstream to help build a more sustainable region.

Many communities in Jakarta are eagerly awaiting the completion of their sewer systems. This project will look to act as a model for implementing sewer management system models in other underdeveloped areas.
