A recent installation of rainwater harvesting system have been increased and all of rainwater harvesting system use its roof surface as water catchment area. However, it has limited uses because of limitative catchment. Therefore this thesis suggest way of collecting rainwater in not only roof surface but building wall if place of high population density like metropolis use rainwater as water for living. To achieve this, we do experiment work in a rainy day using three of scaled model which have different slenderness ratio and evaluate possibility amount of collecting rainwater through the building wall. In addition, we compute a water catchment coefficient to provide baseline data about collecting rainwater in building wall.
