  3. 4. Sanitation We 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.
  4. 5. Heating System <ul><li>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. </li></ul>
  5. 6. Cooking and drinking water <ul><li>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. </li></ul>
  6. 7. Housework <ul><li>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 ! </li></ul><ul><li>A dishwasher uses 20 liters of water …(6% of the water) </li></ul><ul><li>93% of water is used to clean and to wash ourselves … </li></ul><ul><li>You use 8% of the water for your car washing and some other washing … </li></ul>
  7. 8. Swimming pool & Gardering <ul><li>To 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. </li></ul>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.
  8. 9. Good advice <ul><li>Take a shower instead of a bath </li></ul><ul><li>When you wash dishes, don’t let the water drip </li></ul><ul><li>Use your washing machine only when it’s full of clothes. </li></ul><ul><li>Clog every leak as soon as possible </li></ul>
  9. 10. Conclusion <ul><li>Water is essential for life, with no water , we would not survive. It is used in nearly everything we do, we use it to wash things, heat the houses, have fun and more. </li></ul><ul><li>If water ever became hard to find, the humanity would have major problems, that’s why we must do our best to preserve it ! </li></ul>
