The cities of Tenggarong and Samarinda in East Kalimantan are in need of a new source of drinking water, since their current source, the Mahakam river, is said to be polluted. The client of this project, Arsari Enviro Industri, owns a large concession named ITCI of a partly degraded forest 90 kilometers East of Samarinda. This report suggests several design possibilities how to capture water in the ITCI concession area and how to transport it to the aforementioned cities. These design possibilities are based on hydrological and geological research. Additionally, the financial, technical and social feasibility of these solutions is evaluated. From the technical and social analyses it was found the project is feasible. However, during the financial analysis it became apparent that without external or government party involvement it is not feasible.
