Water is a human need for life. The need of domestic water for each person <br /> <br /> <br /> is different, it is usually affected by the number of population and human living <br /> <br /> <br /> standard. One of the way to cater domestic water for human is creating a small <br /> <br /> <br /> dam to save water in wet season and to use water in dry season. <br /> <br /> <br /> The location of this study is in Wabloy Village, Lolong Guba, Buru District, <br /> <br /> <br /> Maluku Province. This study of small dam consist of hydrological analysis, <br /> <br /> <br /> hydraulical calculation, stability analysis, and budget calculation. This design <br /> <br /> <br /> including design of main dam, spillway and rotating basin. Then I also calculate <br /> <br /> <br /> the stability of this dam, and budget estimation. <br /> <br /> <br /> There are a few conclusion about this study. Those are, the planned volume <br /> <br /> <br /> capacity of this dam is 195.480,9 m3 which is able to fulfil the raw water need of <br /> <br /> <br /> 16.464 people by using 13,79 l/s of discharge. And another conclusion is that the <br /> <br /> <br /> stability of this dam is already calculated as a safe stability with a safety factor of <br /> <br /> <br /> 1,5 (when it doesn’t consider earthquake) and 1,2 (when it consider earthquake).
