Second life of water / Washbasin

The amount of water wasted is as considerable as the amount of water we actually get to use. This washbasin helps us reuse such wasted yet clean water.
If the hands touch the pouring water, the used water goes down the drain. However, if the hands don’t touch it (for example, when we shave while the water keeps pouring) the water goes down a separate hole. This hole is covered with a cap which opens and closes with a light pressure and the unused water keeps falling, pushes the cap, opens it, and then finally goes down the hole. This isolated water, therefore, is collected and can later be reused.
