4 Outline of project
Yogyakarta, located in the central Java Island, Indonesia, is a very well known city to all over the world because of its long history and the gigantic religious sites, Borobudor and Pulanbanan. Yogyakarta, where the sewer network/flushing system has been developed, has been suffered from water pollution in the public waters because of the increase of its population and tourists since 1980s. Therefore, in 1990, Indonesian government requested to Japanese government to assist development of sewerage system and support operation & maintenance after construction of sewage treatment plant.
After receiving Indonesia's request, Japanese government made efforts to assist both Indonesian national government and Yogyakarta city by sending JICA Experts; Grant Aid (Construction of sewage treatment plant and main sewer pipes); conducting technical seminars, etc..
