This research report explores rainwater harvesting systems in Klang Valley mosques, Malaysia, as a solution for water security in a region with high annual rainfall. Two case studies, the National Mosque of Malaysia (Masjid Negara) and Al-Muttaqin Mosque (Masjid Al-Muttaqin), are examined to understand their adoption and effectiveness. Qualitative methods, including on-site observations and interviews, are used to gather data. The findings indicate that rainwater harvesting systems are currently implemented in only two Kuala Lumpur mosques, highlighting limited adoption in the region. The National Mosque employs a gravity-fed system with a small tank for its office building, while Al-Muttaqin Mosque uses an indirect pumping system with a larger tank for ablution, toilets, and gardening. The study recommends wider adoption of rainwater harvesting in mosques and public buildings, particularly in areas with ample rainfall. This approach can lead to reduced water bills, raise community awareness of sustainable water management, and support water conservation efforts. States like Taiping, with high rainfall density, are encouraged to implement rainwater harvesting systems in all buildings to ensure water availability during scarcity episodes. Furthermore, mosques, as influential community centers, have a crucial role in promoting sustainable water practices among their congregations and communities. By setting an example through rainwater harvesting adoption, mosques can inspire broader implementation of this eco-friendly approach in Malaysia. Overall, utilizing rainwater as an alternative source is essential to mitigate water scarcity and contribute to environmental conservation efforts.
