2. Water is fundamental… for life…

3. Where will all this WATER end? How can we preserve it ?

4. ECO-LIVING AND SAVING MONEY Eco living is a priority for our future! As we can hear and read natural resources soon will run out, first among them, the water. Despite the knowledge that is necessary for good survival of man and nature, very often it is most our careless use. Just think of the many occasions when you can use recycled rainwater, thus preserving the water-bearing strata and wells. Rain water for many uses is better than the waterworks RAIN WATER More surface More collection With an area of 180 m2 are collected on average 92000 liters With 750 m2 are collected on average 383000 liters With 1500 m2 are collected on average 767000 liters

5. AVOID WASTE WITHOUT SACRIFICES The pie describes the average consumption of water and the possibility of using rainwater when drinking water is not mandatory. Washing machine Watering flowers Car wash Flushing Wc Drinking and Cooking Dishwasher Body cleansing Drinking water Rainwater

6. How the does recycle system work? Collection: all impervious surfaces, which are not subject to the transit of vehicles, are suitable as assembly areas. Filtering : at the entrance of the tank is set up a filter that separates water from other elements. Storage : the heart of the system is the storage tank. We recommend underground tanks. These are hidden from view and protected from accidental damage and maintain the water cooler. Home use : the unit manages a house with dual plumbing system to separate drinking water which feeds the taps from rainwater for other uses.

7. THIS IS AN EXAMPLE OF A SYSTEM Surface collection Subirrigation excess rainwater Drainage Rainwater collection tank Drinking water pipeline Dirty rainwater drain Well of input filtering rainwater Pipes rainwater Management control

8. For our school situated in Corso Vittorio Emanuele II… our goal would be to install a rainwater collection system
