Abstract

The growth of residential areas increases the need for an effective drainage system to prevent inundation. This study plans the drainage system of Anvaya Juanda Housing Estate, Sidoarjo Regency, using a descriptive quantitative approach, hydrological and hydraulic analyses, and the Storm Water Management Model (SWMM) 5.2. The analysis results show that the highest design rainfall intensity for the 10-year return period is 109.058 mm/hour, with U-ditch drainage channels ranging from 0.3 × 0.2 m to 2.1 × 1.2 m. Two detention ponds measuring 40 × 30 × 2 m and 60 × 25 × 2 m function as peak discharge retainers. The total runoff discharge from Sections 1 and 2 is 2.917 m³/s, while the total discharge of the river and housing runoff is 7.189 m³/s. The evaluation result indicates that the existing river has sufficient capacity to accommodate the additional runoff. Therefore, the proposed drainage system and detention ponds can support runoff and flood control in the residential area
