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.
