The water may enter via the perimeter drains of a basement waterproofing system, funneling into the basin or because of rain or natural ground water, if the basement is below the water table level . </P> <P> Sump pumps are used where basement flooding happens regularly and to solve dampness where the water table is above the foundation of a home . Sump pumps send water away from a house to any place where it is no longer problematic, such as a municipal storm drain or a dry well . </P>
