There are several ways to avoid wasting water such as: when take shower, when wash the dishes, when washing a car, when washing a motorcycle and washing the house.
To take shower is a simple way to save water. It because when we pass dove in order to lather we can close the tap avoiding wasting water on this way. We need to to this because I want to highlighted water has finite resources. In my city for example more then one time a district called Vale verde occurred lack of water.
It is very common seeing women washing her house with water hose and I consider it a wasting water because they can only brush the trash instead of doing so. The same instance is valid when I talk about washing the motorcycle and washing the dishes. Is recommended close the tap always.
Finally, if everybody had aware the right way of use water I have no doubt water consumption will decrease a lot .
