Project description

Background:

Due to its location in the tropics, the Island Java (Indonesia) is in principle rich of rainfall. Anyhow the south coast area of Java suffers from water shortage during the 3-4 month dry season with only little precipitation. As a result of the special hydro-geological situation of the karst bedrock, most of the precipitation immediately trickles into karst caves. As a consequence there are no surface waters that could provide water during the dry season. The insufficient water supply is one main reason for poor living conditions in the rural areas and can be seen as one reason for the migration of young people ("brain drain") to large cities like Yogyakarta.

In contrast to the lack of surface waters, there are big amounts of subsurface (karst) water resources available with high potential for drinking water development. In this regard, Integrated Water Resources Management is expected to secure a sustainable development in drinking water development, allocation and sewage disposal considering particularly hydrologic, hygienic, ecologic, economic and social aspects as well as cultural conditions and institutional frameworks.

Goals of the project:

At first, during a 6-month-old pre-project-phase, integrated concepts for water resources management are developed in close cooperation of German and Indonesian project partners of science and industries. The intended key activities are subdivided into the following 6 work packages:

  • Management of water quantities (drinking water development, power generation)
  • Drinking water supply, water treatment, water quality
  • Sewage-/ Waste treatment
  • Ecologic and economic assessment
  • Technology assessment and socio-economic conditions
  • Implementation/ technology- and know-how-transfer (capacity-building)

The project is expected to set a good example for further projects.

Key activities of ITAS:

  • Analysis of the present economic and social conditions in the area under investigation
  • Analysis of fresh-water provision
  • Derivation of requirements from the integrative concept of sustainable development
  • Cost-benefit analysis for the assessment of alternative scenarios (drinking water supply, sewage- and waste treatment)
  • Consideration of social acceptance of intended technologies.
