Abstract: The supply of sustainable raw water has the aim of developing water resources, so that, water use can be efficient have an economic value, good quality, sustainable and everlasting. The research objective was to determine the sustainability status of raw water supply in the Ciliman watershed. The types of data used are primary data and secondary data. Data sources are collected from the field, library and experts. Data collection methods include library studies and surveys. The developed survey technique were in-depth interviews and questionnaire. The method of data analysis was done using the MDS approach with the modification of Rapfish to RapCiliman. The results of the study shows that the level of sustainability of management in general is categorized as sufficiently sustainable including, ecological dimension 56.53% (quite sustainable), 62.90% economic dimension (quite sustainable), 46.76% social dimension (less sustainable), institutional and legal dimensions 46.13% (less sustainable) and technological dimensions and infrastructure 66.49% (quite sustainable). The main lever attributes of sustainability include; ecological dimensions namely, flood frequency (3.77), drought frequency (3.49) and run off coefficient (2.53), economic dimension, namely: availability of raw water supply funds (8.40), water utilization rates (6.66) and investment climate (6.48), social dimensions, namely; public understanding of the sustainability of natural resources (4.82), population pressure (3.78) and community participation in watershed management (2.10), institutional and legal dimensions, namely: organizational capacity of the institution (8.89) and clarity of responsibilities for natural resource management (8.56), dimensions of technology and infrastructure, namely: water building value (9.49), acceptance level for technological innovation (8.61) and type of water supply installation (8.06).
