In a toilet (1) comprising a toilet bowl (2), the water-saving system comprises: - a first emitter (21) for emitting a first beam having a first wavelength (λ1) comprised between 300 and 495 nm, a second emitter (22) for emitting a second beam having a second wavelength (λ2) comprised between 590 and 900 nm, at least one detector (30, 31) for receiving said first and second beams, the first emitter, second emitter and detector(s) being installed on the toilet such that the first beam and second beam pass through the water contained in the toilet bowl before being received by the detector(s); - a controller (8) for receiving and processing data from said detector(s), said data representing the waste level in the toilet bowl; - a flush volume actuator (10) actuated by said controller for flushing a variable volume of water as a function of said data, so as to minimize said volume of water. |
