The final report is made to determine the cause of puddle of water on the existing network of drainage network in the area of Amphibi Kelurahan 20 Ilir DII Kota Palembang. From the study of existing drainage network and the result of calculations by taking into account the wider catchment area discharge rainwater and sewage discharge, it was found that the amount of flow going. Result of discharge calculation compared to existings lines only need to be normalized, while the need for widening the drainage network/ channel redesign the drainage points which have larger discharge calculation of existings for all channels that will be able to accommodate the discharge flow. By calculation catchment area of 233.254 m² obtained the calculation of the dots in the normalization of the channel, T1-T2 = 0,889 m³/sec, T4-T2 = 0,786 m³/sec. While the points made redesign the channel T2-T7 = 3,438 m³/sec, T7-T10 = 5,024 m³/sec, T10-T11 = 7,048 m³/sec. Factors affecting this include conditions due to lack of public awareness to keep the drainage. Keyword : existing and catchment area
