Abstract: 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

Abstract: A readily cleanable water storage system and a method of maintaining cleanliness of water in said system are disclosed. The system comprises an overhead water tank, wherein said water tank comprises a floor, at least one inlet, a draining outlet with a stop cock, an overflow outlet, a supply outlet and a pump, characterized in that 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 the conical bottom and the draining outlet is located at the periphery of the inclined floor at sloping end or at the convergence of the cone formed by the conical bottom.

Abstract: A rescue device for marooned victims consists of a pair of holding arms (10, 10?) for holding the victims and a pair of seating arms (11, 11?) for providing seating facility to the victim. A motor (20) mounted on top of holding arms (10, 10?) moves arms (10, 10?) and (11, 11?) in a direction opposite to each other. The two pair of arms (10, 10?) and (11, 11?) rotate co-axially around main holding bar (40) in directions opposite to each other whenever motor (20) is activated without destabilizing the suspension above, wherein the holding arms (10, 10?) are closed in for holding the victims body by the arc or V shaped structures (30, 30?) when the seating arms (11, 11?) are closed in for providing a seating facility (16) through electrical means (50) and lock (51).
