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.

• 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.

• 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.

keep the water turned off. – Take a shower instead of a bath– Only use the washing machine or dishwasher
when they are full– Repair leaks– Flush the toilet only when necessary
