Abstract

La présente invention concerne des solutions de conception pour atténuer les quatre défauts majeurs suivants dans la conception de système de pompe classique, à savoir, (1) défaillance inattendue de pompe dans une conception de pompe unique qui peut conduire à un dégât des eaux coûteux ; (2) menace d'électrocution mortelle par haute tension dans une situation d'inondation ; (3) coupure de courant de réseau et aucune alimentation en énergie pour fournir la puissance de pompage nécessaire, ce qui entraîne un dégât des eaux ; (4) mauvaise odeur provenant d'un film d'eau stagnante dans le puits après une période de faible taux de trempage avec ou sans pompage activé. Les principes décrits dans la description de l'invention permettent aux conceptions proposées de pallier complètement les quatre problèmes majeurs de conception mentionnés ci-dessus.
