In the province of Yogyakarta in Java, the district of Gunung Kidul is considered to be one of the poorest areas in Indonesia. Here, water shortages greatly affect the population, especially during the dry season, which lasts from April to October. Sanitation Systems in Gunung Kidul consist, either pit latrines or pour flush toilets. Without any treatment the liquid phase infiltrates in to the ground and the septic tanks are hardly ever emptied, thus posing an evident contamination potential to groundwater. So, the current situation about waste water and its treatment is inadequate. Due to this reason within the Integrated Water Resources Management Indonesia Project (IWRM) a so called pilot village Pucanganom was selected to develop an appropriate waste water treatment system considering basis conditions and resultant indicators which were weighted by the Analytical Hierarchy Process Method (AHP). The following paper will describe the application of the method to find an adaptable sanitary system for a village in Gunung Kidul, Indonesia.
