• The principes and examples

a. Waste preventing
b. Use durable sources

• Like in Van Hall Institute Holland

c. Rainwater recovery system

• Like in Ecoconcept Centre Italy

d. Phytodepuration

• Conclusion

a. Waste preventing

• 1. Water saving toilets.
• 2. Water saving taps.
• 3. Short hotwater pipes.
• 4. Smooth surfaces.

1. Water saving toilets.

• Water saving toiletreservoir. The toiletreservoir
  use 3 to 6 litres water at one time.

2. Water saving taps.

• Watersaving taps
• reduce water quantity

• litres of water per
• minute.

  because you dont have to warm up the long pipe.

b. Use durable sources like at Van Hall
Institute.

• 2. Use rainwater for flushing the toilets and to
  water the garden.
• 3. Reuse the water from shower and laundry again
  (water purification)

d. Phytodepuration

...Conclusion...

• There arent many differencies between the
  Netherlands and Italy about water. In both
  countries we save water in the same way, that is
• storing rainwater
• depurating the dirty water and reuse it, for
  example for flushing the wc, to wet the
  garden or for many other uses
• sparing the water.
• In both countries we try to increase the use of
  the techniques to spare the precious water!!! ?
