Water Savings in Places of Worship: A Case Study for St Mary’s Mosque in Australia

Abstract

Water is used for various religious purposes, including ablution for billions of Muslims around the world. Water savings in ablution can make a positive contribution towards achieving the water-related sustainable development goals (SDGs). A survey-based study was conducted at St Mary’s Mosque in Sydney, Australia, to understand the water usage during ablution and how water can be saved by Muslims in mosques. It has been found that the participants of the survey use 4 to 8 L of water to perform one ablution. About 82% of the participants are careful about saving water in ablution. It has also been found that about 70% of the participants believe that wastage of water during ablution is ‘haram’ (unlawful). Some 95% of the participants believe that religious motivation can play a significant role in saving water during ablution, and Imams can make a notable positive difference by encouraging their followers to save water during ablution. It has also been found that 64% of the participants are willing to use harvested rainwater for ablution. The findings of this study will help Muslims in Australia and around the globe to save water and contribute to the circular economy, as saving potable water (by reducing water use during ablution and using harvested rainwater at the source of water collection) saves energy and encourages responsible consumption.
