<p>The invention consists of a system that exclusively uses gravitation and the energy contained in the water supplied by water utility systems, as energy sources to collect, store and reuse bath grey water in individual household applications. The invention is characterized by the combination of a small size hydraulic turbine (2) and a small size hydraulic rotating pump (6), both coupled through a common rotating shaft (4), forming a single device used to extract energy from the water being supplied by the 'water utility system and simultaneously use that energy to pump recovered bath grey water to a higher level of gravitational potential energy. A grey water accumulation tank (3) located at a lower gravitational potential energy level together with a grey water storage tank (5) located at a higher gravitational potential energy level complete the core of the system.</p> |
