It is nearly the same, like saving energy: Only use it if you need it. So turn of the water while you brush your teeth, take a shorter shower, install water-saving shower heads or flow
restrictors and use the dish washer for full loads only.
Drink tap water
We wanna save water, because its a rare good and we need it to survive. An adult needs to drink around three liters a day, depending on temperature and physical exertion. Please drink
these three liters from your tap and do not buy bottled water. So you can avoid plastic bottles or you can save the energy which is used to produce glas bottles.
