Abstract

Land use change due to the development of residential areas, offices and shops in Kenangan Bawah of Taliwang City has caused inundation problems due to the reduction of rainwater absorption area. The purpose of this research is to analyze the factors affecting drainage with infiltration well systems and the capacity of infiltration wells needed. This research uses quantitative method with infiltration well construction management method approach. The results of this study are the factors affecting the management of infiltration well drainage are planning factors by taking into account the hydrological and hydraulics conditions of the existing drainage, infiltration wells using concrete buis construction with a diameter of 80 cm and a depth of 200 cm with an infiltration capacity of 0.017 m³/sec of 22 units with an implementation cost budget of Rp 180,650,000.00 (one hundred and eighty million rupiah six hundred and fifty thousand rupiah).
