1. Water Cycle The water evaporates from the rivers, seas, lakes and forms clouds. When the temperature decreases the water vapor becomes liquid and rain occurs. Water returns to the surface.

2. Resevoir – El Gergal A part of the water can be stored in a reservoir.

3. This water isn´t drinkable so it´s necessary to divert it to a water station where the water is treated (decantation, filtration and the adding of chlorine and fluorine) and turned into drinkable water. The water is then stored in a big water tank and after it is distributed to our houses.

4. We use water to wash, to shower, to clean, to drink, to cook, etc. After using the water, it becomes dirty again where it then goes to a waste water plant.

5. In this plant the waste water is treated in order to get rid of contaminants before draining into the rivers. Water Treatment Plant - Ranilla
