In general drainage can be defined as a series of water structures that function to reduce or remove excess water from an area or land, so that the land can be used optimally. The purpose of this research is to plan the drainage system of the Istana Safira Dau housing in Malang Regency, which in general is not all planned. Analysis and data management methods used are manual calculations in accordance with the rational method for calculating discharges, and the formula for finding the water level using h SNI for channel discharge. After the calculation, the primary channel dimension is obtained with the base channel width b = 0.50 m and channel depth 0.50 m, secondary channel dimensions are channel width b = 0.40 m and channel depth is 0.40 m, tertiary channel dimensions is channel width = 0.30 m and channel depth 0.30 m with guard height for each channel is 3% of the planned channel depth. Rectangular cross section of a rectangular channel.
