Description of a preferred embodiment

As shown in the attached figures, it appreciate a system for the reuse of wastewater domestic, particularly applicable to reuse wastewater generated in bathtubs, sinks and the like. Such a system comprises a ducting (1) from the bathtub body (2) or element similar usable in daily hygiene, which sends waste water already used towards a demineralizing device (3) through drive means, such as, for example, a pump (4) of the type of double speed The pipe (1) is connected to the hole overflow of the bathtub (2) and the drain hole located in the base of the bathtub itself (2).

The mineralizing device (3) is coupled to a feed pipe (5) that provides a flow of water from the supply network that has a solenoid valve (12) responsible for opening and cutting the water supply. In this way, the flow of wastewater from the bathtub (2) or similar and the water flow of the supply network pass through a ozonation device (6) until a deposit is accumulated (7) that it is provided with heating means, and in which a accumulator tank (7) is connected through a pipe (8) with the water outlet tap (9) connected to the bathtub (2) or Similary. Once the water is inside the reservoir accumulate (7), the heating process is carried out for an approximate period 3-4 minutes at a maximum temperature of 40 degrees centigrade

In addition, a level buoy (13) is included in the inside the accumulator tank (7) that is linked to the unit of electronic control and management, so that when the buoy of level (13) reaches a predetermined level or position, sends a signal through the control unit to the solenoid valve (12) provided in the power supply pipeline of the supply.
