The drainage system is an infrastructure which controls the water to prevent the flood and to maintain the public health. There are two concepts of the drainage system, conventional drainage and eco drainage. Universitas Gadjah Mada still using the concept of conventional drainage. In this final project, the writer evaluates the drainage system at Universitas Gadjah Mada Yogyakarta using EPA SWMM 5.1 software. The methodology used by the author is the research methods used in this final project are interviews, observation, participation, and literature. The analysis using in this final project are hydrology analysis, land-use analysis, hydraulic analysis, and management and maintenance analysis. The evaluation of the drainage system will use the calculation of the area is based on the location of the rain station with the calculated average method. Hydrology analysis using frequency analysis and SCS-CN rainfall effective method. Land-use change analysis in the Universitas Gadjah Mada area. Hydraulic analysis using EPA SWMM 5.1, and the management and maintenance analysis of drainage system of Gadjah Mada University. Based on the result of the simulation scenario, installation of the low impact development using permeable pavement that provides a significantly reduced runoff. The runoff coefficient using permeable pavement is 0,23. The peak of runoff using permeable pavement is very slowest than another. Permeable pavement installation is considered very effective.
