Characterizing water use at mosques in Abu Dhabi

In areas where Muslims constitute much of the population, mosques can account for a significant portion of overall water consumption. Among the various uses of water at mosques, ablution (i.e., ritual cleansing) is generally assumed to be the largest, by far. As part of an initiative to reduce water consumption at mosques in Abu Dhabi, we collected data on ablution and other end uses for water from hundreds of mosques in and around Abu Dhabi City. This paper takes a closer look at how water is used at mosques in Abu Dhabi and presents a set of water use profiles that provide a breakdown of mosque water consumption by end use. The results of this research indicate that cleaning the mosque (primarily the floors) and some of the other non-ablution end uses at mosques can account for a significant portion of the total water consumption and significantly more than was anticipated or has been found in other countries.
