This is done through the use of high efficient products in using water and studying how to apply them in buildings. Or buildings under construction. This study led to knowledge of the water saving rate after application. Since the world is currently pursuing the principle of sustainability and green architecture and the principle of recycling and reuse, it realized that some of the objectives of sustainability is to improve the efficiency of water use by recycling rain water, gray water and black water and reuse for purposes that do not require potable water such as agriculture, Cars and others. After comparing traditional buildings with buildings with water recycling systems applied and applying modern technologies that increase water use efficiency, these systems provide 80% water UR - http://172.23.153.220/th.pdf ER -
