Abstract

Pulogangsa settlement is one of the settlements in Ambon City that is often flooded. The cause of floods in Pulogangsa settlements is the overflow of rivers and the limited space for recap. Thus, the solution given is the application of the Well of Recapture. These wells are made to collect rainwater and then impregnated into the soil. This paper requires rainfall data and home type data to calculate the intensity of rainfall and discharge, and the soil permeability data to design the absorption wells. The method used to calculate the rain intensity is Mononobe method, for the calculation of the design debit used Rational method, for soil permeability value is done by visual color analysis and soil structure visually, and for the calculation of the well height used Sunjoto method 1988. Based on the result of analysis, radius of well (R) 0,5 meter and height of well (H) 3 meter. The number of wells placed is 149 wells. So the volume of water that can be impregnated is 351.214217 m3.
