READILY CLEANABLE DUAL PURPOSE WATER STORAGE SYSTEM AND METHOD

摘要

A water storage system comprising a tank having a first inclined or conical floor at the bottom of the tank, a second inclined or conical floor above the first inclined or conical floor, dividing the tank into upper and lower compartments, one or more inlet(s), an overflow outlet, a first draining outlet located at the sloping end of the first inclined floor or at the convergence of the first conical floor, a second draining outlet located at the sloping end of the second inclined floor or at the convergence of the second conical floor, and a consumer supply outlet located above the second inclined floor or above the second conical floor, wherein the upper compartment holds potable-grade water and the water from the lower compartment is reserved for fire fighting needs and used for non-potable purposes with periodic replenishment from upper compartment

主权项

1. A readily cleanable dual purpose water storage system comprising:
an overhead water tank for storing water; 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 said water tank comprises:
a first inclined floor at the bottom of the tank, wherein the first inclined floor is inclined at a pre-determined continuous and effective slope towards another point on the periphery to form an inclined floor;a second inclined floor located above the first inclined floor at a predetermined height, thereby dividing the water tank into upper and lower compartments;one or more inlet(s) located near the top of the upper compartment for letting water to be filled into said tank;an overflow outlet;a first draining outlet located at the lowest point of the slope of the first inclined floor, with a stop cock fitted thereto;a second draining outlet located at the sloping end of the second inclined floor such that water and impurities from the upper compartment moves down to the lower compartment; anda consumer supply outlet located at the side wall above the starting end of the second inclined floor through which water is supplied to consumers; wherein the upper compartment holds potable grade water for supply to consumers and the water in the lower compartment, which comes out of the first draining outlet, is (a) reserved for fire fighting needs and (b) used for other non-potable purposes with simultaneous replenishment from the upper compartment.
