Sambu Island is one of the largest oil supply islands in Indonesia. The Sambu Island Fuel Oil Terminal (TBBM) became the first Bonded Logistics Center (PLB) with oil and gas commodities in Indonesia. In the oil processing area, it is necessary to have an adequate drainage system so that rainwater does not mix with oil processing waste. Flood control caused by inadequate drainage system is done by re-planning the drainage system. In the process of redesigning the drainage system, a 10-year return period of 266.91 mm of rain was used with the Log Pearson III method. In planning the drainage channel is basically divided into 3 channels, namely tertiary, secondary, and primary channels. The open drainage channel used is rectangular, and for the closed part, the culvert uses a box culvert. In calculating the dimensions of the drainage channel redesign using the SCS CN method of discharge assisted by the SWMM application. Then a hydraulic simulation was carried out using the SWMM program to determine the water level and discharge in each channel.
