<![CDATA[De Naila Village Housing is located in Menganti Subdistrict, Gresik, there is an area that is still under construction, so an appropriate drainage system planning is needed. Therefore, this research is planned to combine manual calculations with EPA SWMM 5.2 software. The method used in this research is a descriptive method described in hydrological and hydraulics analysis. After both analyses are successful, the results of the analysis are included in the EPA SWMM 5.2 software. The results of this study obtained the De Naila Village Housing drainage network scheme forming an elbow pattern. The total runoff discharge is 3,193 m3/s. The area drainage channel uses a u-ditch cross section originating from PT Waskita Beton Precast, with the smallest dimension of 0.3x0.3 meters for tertiary channels, whilethe largest dimension is 1.2x1.2 meters for primary channels. drainage network design in De Naila Village Housing using EPA SWMM 5.2 software shows the continuity error value of all drainage channels is less than 10%. The number of storage ponds is 3 units with dimensions of 40x40x1,5 and 30x30x1,2 meters. The highest river discharge was 33,026 m3/s at a height of 5 meters. In the rainy season the maximum height is at 3 meters]]>
