This project aims to conduct a water conservation initiative in school environment in Malacca state (Malaysia). Water footprint findings demonstrated that approximately 60% of total water use was due to toilet use. The rainwater harvesting system was selected as this method enables the use of a renewable source (rainwater), conveniently fit the existing building rooftop and plumbing system. The rainwater harvesting system at school lavatory has led to significant reductions between 24m3 and 278m3 of water use with water bill saving of USD285. Benefits gained from this water conservation initiative in school can be seen from environmental, social and economic perspectives.
Utilization of renewable resources via harvesting rooftop rainwater helps to reduce treated water use and to limit land impact while optimizing land use and landscape diversity in school environment. Moreover, responsible consumption of renewable rainwater contributes to wealth creation via water bill savings.
