This paper presents the development of rainwater harvesting (RWH) system at Sekolah Menengah Kebangsaan Iskandar Syah ( SMKIS ), Melaka to promote landscape sustainability. The proposed RWH system deployed an elevated tank, a sequential filter, and a storage tank. A fertigation pond and a turbine were installed as part of the RWH system in Taman Herba to promote an ecosystem for freshwater habitat and to generate energy. The RWH system was used as an alternative water supply to the Taman Herba and the fertigation pond as well as water supply for power generation. It was found that the RWH system has successfully reduced the rainwater flowrate in the existing drainage system by 50.9% and effectively reduced the utility bills for the landscape irrigation and the fertigation pond. The turbine generated 26.6 W power which is adequate to light up a scrolling message board at Taman Herba . Both the fertigation pond and the turbine embellished the Taman Herba landscape and are a good platform for experiential learning for the secondary students in SMKIS .
