A flood control system for use in a structure having a basement floor below ground level is provided. The flood control system comprises a sump, a main pump positioned in the sump, and a secondary pump positioned in the sum. The secondary pump is raised relative to the main pump to a predetermined elevation. The main pump is energized when a height of water within the sump is at a first level. The secondary pump is energized when a height of water within the sump reaches a second, higher level and is de-energized when a height of water within the sump drops to a third level. A cover is releasably mounted to the sump. The cover includes a first section for covering the main pump and a separate second section for covering the secondary pump. At least one of the first and second sections is hingedly mounted to the sump. A controller is operatively connected to the main pump and the secondary pump. The controller is responsive to water level within the sump to selectively energize at least one of the main pump and the secondary pump.
