Malaysia is a country located on the equator line which is a humid and hot climate throughout the year. Therefore, Malaysia will receive a huge rainfall every year. It is estimated Malaysia receives rain between 50 mm to 500 mm monthly [1] and receives rainfall between 1500 to 3000 mm per year with an average of 2400 mm [2]. Ministry of Energy of Green Technology & Water of Malaysia, [3] has also emphasized nine water demand management strategies, particularly in the domestic, industrial and agricultural sectors in Malaysia. Water demand management is an effective method of managing sustainable water resources in the country. One of the strategies is the exploration and use of alternative water sources such as rainwater as one of the main water sources to reduce the pressure on existing water resources and can reduce water usage involving money. Therefore, with this rainwater harvesting system initiative can help to ensure the sustainability of water supply for next generations and future development. Sustainable development focuses to provide a balance between economic and social development to address environmental requirements [4]. Besides that, rainwater harvesting system is a very effective innovation that have currently been done in Malaysia. Sustainable construction also has begin to expand and focused on preserving the environment. Due to the government's commitment towards green development, through the ‘Green Growth Development' proposal and the launch of 'Green Building Index' (GBI), rainwater harvesting systems are being implemented as green initiatives to promote efficient water usage [5]. Most developments in Malaysia are still not implementing this system due to lack of awareness of sustainable construction and rainwater harvesting system is considered a new phenomenon in Malaysia [6].
