Sump container designed to permit gravity flow of flood water from a basement floor through the cover into the sump container and to permit the pumping of water from the container through a discharge conduit passing through an opening in the cover. The cover has a transverse opening to receive a discharge conduit for water pumped from the container to an outside drain, a dividing line through the transverse opening and separating said cover into two removable cover sections, and an air-sealed water inlet through the cover to permit flood water to flow into the container while retarding the escape of odor, radon, moisture and pump noise from the container.
