SanitationWe see that baths and showers are a major part of the consumption, the water used through a shower is less dirty, we could use it again as a toilet flush.A normal person uses up to 50m3 of water per year.

Heating System• Hot water heating

systems are built around the premise of radiant heat. Water is heated by a boiler and then circulated throughout a building via a series of pipes that heat radiators. The radiators distribute the heat.

Cooking and drinking water

• We only use 7% of water (of the total water we use per day) in the kitchen to cook . And we use only 1% per day of water to drink, this is not a lot.

Housework

• If you use a washing machine do you know how many liters do you use per machine ? Well you use from 80 liters to 160 liters …(11% of the water ) That’s a lot, so don’t wash when you don’t really need to !

• A dishwasher uses 20 liters of water …(6% of the water)

• 93% of water is used to clean and to wash ourselves …

• You use 8% of the water for your car washing and some other washing …

Swimming pool & GarderingTo find the amount of water

which is in a swimming pool, you have to use this formula : Lenght x Width x Depth = Water volume. For example, in a swimming pool with 18 meters of lenght, 8 meters of width and 1.5 meters of depth, the water volume would be: 18 x 8 x 1,5 = 216 cubic meters which makes 216.000 liters.

The gardering water represents 7% of households’ water use. Instead of using drinkable water, you could use a bucket to keep the rain to water plants.

Good advice

• Take a shower instead of a bath

• When you wash dishes, don’t let the water drip

•Use your washing machine only when it’s full of clothes.• Clog every leak as soon as possible
