Abstract
Design solutions to mitigate the following four fatal flaws in the conventional pump system design; namely, (1) surprise pump-failure in single pump designs that can result in costly water damage; (2) the threat of fatal high voltage electrocution due to flooding; (3) grid power outage and no energy supply to support the needed pumping power that results in water damage; (4) foil odor from the standing water in the well after a period of low seeping rate with or without activated pumping. The principles described herein can completely mitigate the above four fatal design issues.
