The objective of this study was to develop an Indonesia urban excreta/wastewater disposal prioritizing model based on government strategies and conditions, as well as characteristics. A priority model for selecting project localities for the urban excreta/wastewater disposal program is strongly needed to ensure that limited government money will be spent more wisely and that the people believe that program is being implemented fairly.

The priority model was tested by using 80 selected cities and the results were workable, although only four of the five proposed parameters were used. Since the Indonesian urban excreta/wastewater disposal program was just begun on April 1, 1979, one parameter, namely, technological alternatives cannot be validated. At present the government is still conducting several survey feasibility studies for excreta/wastewater purposes. Thus, what kind of disposal is appropriate for every local condition cannot be decided at present.

is used to determine ranked priorities. The priority model required several parameters which should be relevant to the excreta/wastewater disposal program in Indonesia and also should be suitable to the situation, condition, and feasibility in applying them to the data available. The proposed parameters are health hazards, population density, city potential, water supply condition, and technological alternatives. The Double Delphi Method was used for assigning the weight W(, i) of the five parameters and for scoring categorization S(, ij) of each parameter. For this approach a panel was formed, consisting of thirty-seven distinguished experts from various countries and international agencies who are devoting their time to the study of the urban excreta/wastewater disposal program.
