Water Treatment
Where does our water come from?
Natural water comes from rivers and lakes and goes into
Dams, then, it undergoes a procees where it becomes
drinkable, called ETAP (Drinkable water treatment
station).
Where does the water go after using it?
The used water is evacuated by
canalizations to sewers and thenit's taken to the EDAR (Residual water treatment
station)
Residual water treatment
The objectives in the “depuration station” are:
·Eliminate solids and oxidable materials
·Eliminate toxic substances to avoid environmental damage and sanitary problems
Useful advice

Install water-saving systems
Use the washing machine only when it's full
Don't use the WC as a bin
If you have a garden, control the irrigation
Close the faucet when shaving or cleaning your teeth
