The aim of this study is to build an affordable rainwater storage system for all type houses with easy installation and friendly user. The current con- straints on the installation of rainwater storage system in the market requires a fairly expensive cost, and skilled technical workers to install it. In contrast, the Smart Kit RWH, is friendly built in a complete set that is easy to install and easy to maintain by homeowners. This system is very suitable for the use in agriculture and farming. This Smart Kit RWH consist of water storage tank, existing gutter and main pipe, first flush diverter and some connector pipe to create this complete system. This product is limited to storing untreated rain water quality, and the quality of rainwater collected can be used as water storage for household and sanitary equipment such as flushing cistern and other potable water usage. Nevertheless, this contributes to the good and the benefits of individuals, communities and nations. This product able to help the rural population in particular of having problems in getting clean water. Hopefully, with the production of this system, it can foster the public's awareness of the advantages and benefits of installing rainwater storage systems at home, plantation and farming.

Introduction 1.1 Background of study In this century, the world has realized the re-use of rainwater for home, landscaping and agriculture is very needed. Before the sys- tem was expanded, rainwater had already been collected or cap- tured through the roof of the house and stored in reservoirs. Rain- water is a free source of water that has a near-pure quality of wa- ter. It can be used to supply drinking water as well as non-drinks. For drinks, this rainwater needs to be treated to remove or kill the bacteria contained therein. Rainwater harvesting is the process of collecting, storing, and later reusing rainwater from surfaces such as roofs [1]. The rainwater collection and reuse system or also known as the rain water harvesting system are one of the Best Management Practice in effective water management. The system aims to delay surface runoff flow and promote efficient use of water. Nowadays, most regions around the world have adopted rainwater harvesting to mitigate the effects of floods due to cli- mate change. The rainwater harvesting system was introduced after the 1998 drought by Ministry of Housing and Local Gov- ernment [2]. The initial initiative of RWHS implementation in Malaysia began in 1998 following the water crisis in Kuala Lum- pur. The impact of this water crisis has brought awareness to the Malaysian government to find solutions on how to deal with and mitigate the crisis of the absence of clean water resources. In that case, an effort has been made in Malaysia where the installation of a rainwater collection system was issued by the Ministry of Hous- ing and Local Government which aims to encourage the public to be more sensitive and know about the installation of rainwater collection systems [3-4]. In an effort to intensify the implementa- tion of the installation of rainwater storage systems, by looking at and studying research sources for researchers, the cheap and easy- to-install rainwater harvesting systems will be built to ensure that all societies are able to have a clean water storage system from rainwater. In addition to helping make a positive impact on the environment, there are also many advantages to using this rainwa- ter harvesting system. Among them is, there is no cost to use rain water except for initial costs for system installation [4-5]. With the creation of a cheap and easy-to-install rainwater harvesting sys- tem, it directly contributes to the huge savings of water users in Malaysia, as well as controlling the use of clean water that is often in high demand in Malaysia. The government is also able to make the country as the focus of the world because of its success suc- cessful installation of rain water harvesting system for all levels of society. Therefore, the aim of this study to build facilitate people to install affordable rainwater storage systems. As we know cur- rent constraints installing a rainwater storage system in the market requires a fairly expensive cost, and skilled of technical workers to install it. This Smart Kit RWH is consist of water storage tank, existing gutter and main pipe, first flush diverter and some con- nector pipe to create this complete system.
