While washing hands, a lot of water is wasted while we apply soap. Again if both the hands are dirty then even the faucet needs to be cleaned. To avoid this hassle and wastage of water, I have innovated a foot operated faucet. This arrangement does not use electronics and so it is cheap and repairable. Even third world countries will afford it.
A common man can help to conserve environment by using this device. Consider how much water is saved even if only 5 liters of water is saved per wash-basin per day by using this device. This device is very useful for home, office, factories, hospitals, schools, hostels, hotels and restaurants.
