Definition:
A sump pump is a special electrically operated water pump usually installed in a home's basement. Sump pumps come in pedestal and submersible models with submersible types being the most common. The sump pump removes water that has collected in a sump pit either from leakage into the home, high water table or from flooding. Once a certain level of water is attained, the sump pump turns on and discharges the water away from the house, either into the back yard or into the municipal storm water system (not the sewer system).
