Abstract

L'invention porte sur un système de réutilisation des eaux ménagères par un toilette à chasse d'eau. Les eaux ménagères provenant d'éviers, de douches, de baignoires, de machines à laver et similaires sont pompées et conduites dans un réservoir de toilette. Si nécessaire, le réservoir peut être rempli avec de l'eau potable. Le système peut utiliser les réservoirs de chasse existants classiques, et ne nécessite pas nécessairement un quelconque réservoir de stockage supplémentaire. Le système peut utiliser un réservoir conçu spécialement.
