Flood water retention assembly

A flood water retention assembly being configured to collect and selectively release flood waters, said assembly comprising:

• a plurality of repositories, each of said repositories being positioned proximate a lowland area prone to flooding, each of said repositories having an inlet and an outlet, each of said repositories having a minimum fluid capacity of 1,000,000 fluid gallons, each of said repositories being ventilated for leveling atmospheric pressure within said repository;
• a plurality of inlet valves, each of said inlet valves being fluidly coupled to said inlet on a respective one of said repositories, each of said inlet valves being positionable in an open position to facilitate water to flow into said respective repository, each of said inlet valves being positionable in a closed position to inhibit water from flowing through said inlet on said respective repository;
• a plurality of outlet valves, each of said outlet valves being fluidly coupled to said outlet on a respective one of said repositories, each of said outlet valves being positionable in an open position to facilitate water to flow out of said respective repository, each of said outlet valves being positionable in a closed position to inhibit water from flowing through said outlet on said respective repository;
• a plurality of drain conduits, each of said drain conduits being fluidly coupled to a respective one of said outlet valves, each of said drain conduits being in fluid communication with a drainage area wherein each of said drain conduits is configured to drain the water into the drainage area;
• a plurality of inlet conduits, each of said inlet conduits being fluidly coupled to a respective one of said inlet valves, each of said inlet conduits being in fluid communication with a body of water wherein each of said inlet conduits is configured to receive water from the body of water, at least one of said inlet conduits being in fluid communication with the body of water through another one of said repositories than said associated one of said repositories;
• and
• a pump being fluidly coupled to each of said inlet conduits, said pump being positioned adjacent to the body of water, said pump being positioned at ground level, said pump pumping the water into said repositories when said pump is turned on wherein said repositories are configured to contain flood waters thereby reducing flood damage to surrounding areas, wherein each of said outlet valves is selectively opened for draining the water at a selected rate into the drainage area wherein said repositories are configured to release the flood waters at a controlled rate, said pump having an output rate of at least 50,000 fluid gallons per second.
