[57] ABSTRACT A water supply control system has a faucet actuating means for actuating a water supply faucet to supply water, a light-emitting means for intermittently emitting light as at least a first period, a light-detecting means for detecting light emitted from the light-emitting means and reflected by a portion of the body of a user of the faucet, and for producing a detecting signal indicative of whether the light id detected or not, and a control means for controlling the faucet actuating means to actuate the faucet based on the detected signal from the light-detecting means. The control means comprises an auxiliary light-emitting means for enabling the light- emitting means to effect a plurality of light emissions at a second period shorter than the first period, based on the detected signal from the light-detecting means, and a decision means for applying a control signal to the faucet actuating means to control the faucet based on the number of times in which the light is detected by the light-detecting means, among the light emissions caused by the auxiliary light-emitting means through the light- emitting means.
