ABSTRACT:
A flood control system for use with a building sewer line connected from a building to a city sewer line to prevent back flow of sewage in the line into the building during a flood which includes an underground tank installed in an in-line position with respect to the city sewer line and with at least a portion of the tank lying in a plane below the building sewer line. The city sewer line is cement encased at its point of juncture with the building sewer line beneath the building. The tank has a fluid pump mounted therein and connected by an overhead standpipe for pumping waste fluids from the bottom of the tank back into an inner sewer line for discharge exteriorally to a city sewer line. The tank further has a manually operable gate valve mounted therein. The gate valve is operably connected at one side to the city sewer line and connected at another side with the building sewer line. The gate valve includes a back flow valve which is operable to permit sewage flow only in one direction through the gate valve and in turn through the building sewer line and then to the city sewer line but which back flow valve is physically held in a closed position by any reverse flowing waste fluids to prohibit waste fluids back flowing from the city sewer line into the building and into said gate valve so as to hold the waste fluids and to prevent them from entering the building during flood conditions. The back flow valve is so positioned relative to the gate valve whereby the gate valve is located in the tank but between the back flow valve and the city sewer line permitting the back flow valve to function to shut off the sewage fluids flowing from the city sewer line in the event that the gate valve is left in an open position.
