Water will start running if hands are underneath the water tap, it will stop if hands are far from the water tap. The set up is done electronically. The rate of saving water is possible up to 80%.
3. Water saving devices
Devices which can be installed onto water taps or cisterns. Their costs are low and they have a high benefit considering the water economy. Besides, they are very easy to install.
4. Swivel sprayer
That is a device which mingles water with air. Water drops come out like pearls. It is proven that the rate of water savings is up to 40%.
5. Water saving shower heads or flow restrictors
These devices decrease the water quantity depending on the pressure. The rate of water savings is up to 60%.
6. Shower´s on-off switch for water quantity
