ABSTRACT:
An emergency water tank reservoir system for a structure having a water supply system including a water supply line is described. The system includes a water tank structure having a top wall, a bottom wall, and a side wall forming a closed tank. The tank structure has an inlet port formed in the side wall and an outlet port opening formed in the side wall. A sediment drain valve opening is disposed into the bottom of the tank at or adjacent the lowest point within the tank for periodically flushing sediments from the tank. A water spout opening is formed into the tank and disposed at an elevation above the sediment drain valve opening for withdrawing water from the tank in emergency situations. A bypass water line is coupled between the inlet and outlet port via a bypass valve system for selectively providing a water bypass line to bypass the tank structure. An inlet check valve is connected at the tank structure inlet port for permitting water flow through the inlet port into the tank structure and preventing water flow from the tank structure out of the inlet port. An outlet check valve is connected at the tank structure outlet port for permitting water flow from the tank structure out of the outlet port, and preventing water flow into the tank structure through the outlet port.
