System for collecting water, the unit of deviation of rainwater collection system, rainwater in a pru00c9dio having a captau00c7u00e7o on the roof with at least two drains to the gallery of rainwater through the rail system. A system water collection pipe for collecting water blocks downward from a roof.A descending tube (27) is located adjacent to a unit of deviation of rainwater (31). The unit comprises a box (36) with a tube (27) in a downward opening (37) in the bottom of the box (36).The chute (14) has two openings side by side (39 and 40), the opening (40) has an extravasation in the form of a vertical wall (41), while the opening (39) has a plate of the valve (42) articulated to the front edge in (43). A pneumatic actuator (44) is used to move the valve plate (42) into the closed position.When the valve is closed, the opening (40), and a vertical wall (41) serves as an extravasation of return of rainwater through the box (36). The tube of the tank (17) has an opening (45) with a vertical wall (46), which has its upper edge (47) disposed at a position lower than the upper edge (48) of the wall (41) of the drainage.All the tubes descendants are endowed with units of deviation. A controller includes a rain sensor to detect an event of rain with a retardation time is imposed on the first rinse the roof before the valves close the tubes descendants.When the tank is filled, a ball is used to command the controller to open the valves, if they are closed, or keep them close, in the case of a new event of rain and the tank is already full.
