The uncontrolled of urban built up area growth, as well as the lack implementation of Rain Water Harvesting (RWH) led to an increase of runoff coefficient, so the abundant volume of rainfall in the rainy season directly flows to the river and thrown into the sea. This is supported by the growth of population which triggered the urban built up area expansion as the effect of high migration to Makassar city. Due to this phenomena , the green open space is reduced and as coastal city which intrusion of seawater into land make city lack of ground plain water.
