## 20091127 Fr Use Of Water In Households Group 1 1+2Presentation Transcript

• Use of water in households The various ways in which water is used by households.
• Summary
• 1: Sanitation
• 2: Heating System
• 3: Cooking and drinking water
• 4: Housework
• 5: Swiming pool & Gardening
• 7: Conclusion
•
• 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.
• 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 & Gardering
• 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.
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.
