Abstract


Rapid growth at the time of the event demanded space and resources. Changes in land use in green areas into residential areas which reduce natural infiltration areas which make it difficult for air to absorb and cause surface runoff. Based on these conditions, it is necessary to develop a rainwater management method to reduce flood discharge, either managed by being infused, collected or channeled out of the area with the smallest possible discharge. By implementing a drainage system with an environmental or ecodrainage perspective in the Karawaci Kingdom Park housing area, it is possible to reduce runoff discharge that occurs. Some of the ecodrainage technologies that are applied in the slumping areas are rainwater storage, infiltration wells, biopores, bioretension and retention ponds. Based on the results of the calculation of the housing runoff discharge value of 0.22286 m3/s. By implementing an ecodrainage system, it can reduce 52% of the total area discharge and the rest will flow into the retention pond before being run off to the receiving water bodies. Due to limited land, the pool storage capacity is 900 m3.
