Readily cleanable water storage system and method

A readily cleanable water storage system comprising:

• an overhead water tank for storing water,
• wherein said water tank comprises:
• a floor;
• one or more inlet(s) for letting water to be filled into said tank;
• a draining outlet with a stop cock fitted thereto;
• an overflow outlet;
• a consumer supply outlet through which water is supplied to consumers;
• and
• a pump for pumping water from a water supply source to the overhead water tank for storage of water before supply to the consumers,
• wherein the floor of the tank is inclined at a pre-determined continuous and effective slope either towards another point on the periphery to form an inclined floor or from all sides to form a conical bottom with the supply outlet located at the side wall of the tank above a starting end of the inclined floor or above the conical bottom, and the draining outlet is located at the periphery of the inclined floor at the sloping end or at the convergence of the cone formed by the conical bottom, as the case may be, in order to completely discharge the water stored in the tank when draining outlet is opened so that no stale water is retained and wherein said inlet(s) is/are provided with multiple openings or pores to discharge jets of inlet water at different points on the starting end of the inclined floor of the tank or at various points on the inclined surface of the conical bottom of the tank thereby helping to dislodge the impurities adhering to the bottom of the tank more reliably.
