Deskripsi
The increasing of land use can affect an extreme waterflow posed a threat of flooding and drought in downstream watershed. Handling runoff using the drainage system has been implemented. But the urban settlement land is very limits, so it's necessary to control runoff effectively and efficiently. The objective of this research is to apply zero runoff concept using infiltration wells in a small part of settlement in North Bandung. The used methods are a rational method and Sunjoto method. The research location is a part of settlement area in North Bandung. The results show that on 20-year rainfall return period, the runoff from drain 1 is about 0.0182 m3/s and from drain 2-3 is about 0.0104 m3/s. The first infiltration wells (A) (diameter of 0.8 m and a depth of 15 m) can infiltrate 0.0244 m3/s to absorb from drain 1 and the second one (B) (diameter of 1.2 m and a depth of 10 m) can infiltrate 0.0181 m3/s to absorb from drain 2-3. The infiltration wells can accommodate runoff in the 20-year rainfall return period, so the zero runoff concept can be applied in other settlement parts that exist in North Bandung area.
