Water is the basis of any life -
a reliable water supply system
is the basis for survival of any civilization!

The district of Gunung Kidul in the Yogyakarta Special Province classifies as one of the poorest regions in Java and the whole of Indonesia. One of the essential reasons is the acute water scarcity during the months of the dry season. In addition to the poor harvest in agriculture, the drinking water supply is strongly impaired. As a consequence to the poor living conditions the intellectual people of the population have migrated away and thus causing the stagnation of the region’s development.

During the 1980s a British Consulting Agency carried out an extensive survey of the region and reported evidences of large deposits of water under ground. However a self-sustaining solution of water supply was not found.

In the summer of 2000, a team from the Institute for Water Resources Management, Hydraulic and Rural Engineering, University of Karlsruhe entered the Caves, which was made possible through an initiative of the national nuclear agency of Indonesia BATAN. Later with the support from BMBF, the Federal Ministry of Education and Research of Germany and along with an intimate collaboration with several Indonesian institute partners, a feasibility study was carried out to find out ways of developing the available resources.

Subsequently after the feasibility study, since the autumn of 2002, the inter-disciplinary joint project was granted aid from the BMBF. The governor of Yogyakarta, Sri Sultan Hamengkubuwono X would patronize it from the Indonesian side. Scientists from Civil Engineering, Geo- and Environmental sciences and Geography along with industry-partners in the specialized fields of tunnel construction and turbine development, would intensively participate in the realization of the pilot project, "Underground Water Management in Wonosari", Yogyakarta.

The further extension of this scheme is to initiate strong ’capacity building’ measures through elaborate training and exchange programs, which is an essential part of the German-Indonesian co-operation.

We sincerely hope that the team effort of all the partners would finally contribute to the improvement of the living conditions of the Gunung Kidul population during dry seasons and kick-start a series of projects in similar Karst regions around the whole world.
