The drainage paradigm that has been used in Indonesia is conventional drainage, which removes the rainwater runoff as soon as possible to the water body. The paradigm can be changed by managing the water resources at the plot or regional level that can be started from the educational area. Jatinangor Bandung Institute of Technology (ITB) Campus is an educational area located in Sumedang Regency, West Java. Jatinangor ITB Campus occupied an area of 460,353 m2 consist of 70.77% of open field and 29.23% of constructed area. Under the current campus construction condition, Jatinangor ITB Campus produced 2.65 m3/s runoff by 102.12 mm/day rainfall and 66.31 mm/hour rain intensity at 10 years return period (PUH). Drainage system optimization was needed to reduce runoff and improve water conservation at Jatinangor ITB Campus. The steps to design included analyzing rainfall data; existing area condition, soil, and the building roof; dimensions and supporting components; and analyzing the runoff discharge. By the conditions of low soil infiltration potency, the design of drainage system optimization that could be done was applying ecodrain like green roofs, wetponds, wet swales, and filter strips. The technologies were applied as a water resources management in plot and regional level so that will increasing the water conservation value, aesthetics, and biodiversity. By applying green roofs in three buildings and construct a wetpond on available land, runoff could be reduced by 0.082 m3/s.
