Electronically controlled water flow restrictor to limit the domestic wastage of water

Water scarcity affects more than 4 billion people in the world. One of the most critical challenges faced by the world is water shortage. The proposed idea aims to conserve water, by introducing a regulatory system that reduces the rate at which water is obtained at the outlets in a house after a specific volume. The proposed system must be installed at the inlet of every house. Once 80 percent of a specific maximum volume of water is reached, the rate of water flow at all the outlets of house will automatically decrease. The volume of water used is detected by a water flow sensor. A micro-controller receives the input data and electronically reduces the outlet rate of water flow by using a solenoid electro-valve. If this system is implemented in every household, the global scarcity of water can be effectively reduced.
