CHAPTER 1 INTRODUCTION 1.1 BACKGROUND Rainwater harvesting system (RWHS) is a direct collection of water from roofs and other purpose built catchments. It is also as the collection of sheet runoff from a made-man ground or natural surface catchments and rock catchments for domestic, industry, agriculture and environmental use (Abdul Hamid & Nordin, 2011). Normally, RWHS is depended to the size of the roof catchment area and the available rainfall. RWHS usually have six components. There are the catchment area, gutter and downspout, a filtration system, a storage system, a delivery system and a treatment system. According to (M. Martim & W. Watkins, Jr, 2010, pp. 2000-2009) RWHS is a roof collection system which has three main…show more content…
The government is trying to promote the application of RWH systems in buildings, houses, mosques and others. Therefore, the RWH systems are not considered as a new phenomenon. The RWH systems apply an environmental friendly design. People throughout Malaysia lack enough knowledge of knowing the benefits RWH systems. Within the support and effort of government in promoting the application of RWH systems, the numbers of buildings and others using the RWH systems increased. The establishment of National Hydraulic Research Institute of Malaysia (NAHRIM) make people aware to study how the importance of RWH systems actually. Based on NAHRIM, approximately RWH systems begun implemented during of drought crisis in 1998 which brought unpleasant water supply disruptions for Klang Valley folks. Although, the application is still ongoing, the implementation of RWH systems in building offices not widely use. This implementation is executed more on green building offices. From these circumstances, it seems like RWH systems only competence to the green buildings because RWH systems is non environmental impact and it design for green. Here, we will look how far differences of efficiency RWH System between green building and non green building on this study. Besides, RWH systems are described as water and energy efficiency that had further explained in background. Although, RWH
