Drainage becomes an essential tool in an urban area. A city can be said neat and orderly if its drainage facility can accommodate any existing water discharge, either from rain or the flow of household disposal. Jalan Pope Pekanbaru is the connecting road between Tuanku Tambusai road and Arifin Achmad street. Pope road condition is very strategic then Pope street becomes one of business area in Pekanbaru. ). This study aims to determine the capacity of the drainage channel of the city of Pekanbaru whales against the intensity of rainfall in the city of Pekanbaru. The method used is direct survey sampling to the field then analysing precipitation, frequency and probability of rain by using four types of distribution used in the field of hydrology that is Normal Distribution, Normal Log Distribution, Log Person Distribution III and Gumbel Distribution type 1, rain intensity with mononobe method. Because short-term data is not available, Calculates the discharge plan and the drainage channel. Based on the results of the 5-year Planet Bit Flow analysis using the Gumbel type 1 method of 247.53 m / s, the flow of existing drainage (Q) is 0.6245 m / sec, while the peak flood flow (Qp) is m / seconds
