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.

Watersaving taps: reduce water quantity till 40 %; for example a shower can save 4 to 6 litres of water per minute. 2. Water saving taps.

3. Short hot water pipes Use short hot water pipes. You will save energy, because you don’t have to warm up the long pipe.

4. Smooth surfaces With smooth surfaces you will save cleaning water and it’s easier to clean up the underground.

b. Use durable sources like at Van Hall Institute. 1. Store the water and use it in the dry periods. 2. Use rainwater for flushing the toilets and to water the garden. 3. Reuse the water from shower and laundry again (water purification)

c. Rainwater recovery system to supply irrigation plant and WC flushes

As we saw at the Ecoconcept Center

d. Phytodepuration The phytodepuration is a chemical proccess that uses plants to filtrate the dirty water and reuse it for flushing toilettes and to wet the garden.

Phytodepuration

...Conclusion... There aren’t 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!!!
