The quantity of storm water on AL ¿Shifa Hospital is heavy and concentrated in a short time. This study applies a holistic view for the potential of managing harvested storm water within Al-Shifa Hospital. Different options for storm water management in Al-Shifa hospital were investigated based on quantified storm water quantities, namely (1) storage approach to support direct residential uses, (2) storage approach to support irrigation, and (3) combination between irrigation and artificial recharge.
