In the province of Yogyakarta in Java, district of Gunungkidul is considered to be one of the poorest areas in Indonesia. Here, water shortage greatly affects the population, especially during the dry season, which lasts from April to October. The peculiarity of Gunungkidul is that despite high rainfall of about 1,800 mm per year, the water supply of the population is not guaranteed. Because of the karstic underground, rainfall rapidly seeps into the ground without sufficient surface storage. The current situation of sanitation systems consist of pit latrines or pour flush toilets and results in an inadequate waste water treatment. Untreated liquids infiltrates into the ground, thus posing a significant threat to groundwater quality. Owing to this reasons mentioned above, an integrated water resources management (IWRM) was established in the district of Gunungkidul. The aim of the IWRM-Indonesia project was to develop adaptable and sustainable technologies for the supply of the population in the project area with water in sufficient quantity and quality as well as the improvement of the waste water treatment situation, which is the focus of the study presented herein.
