A flushing control system for prisons and the like includes a fixture and a source of water. A solenoid operated valve is interposed between the fixture and the source for regulating the flow of water to the fixture. A capacitance sensor is operably associated with the fixture for requesting operation of the valve. A control mechanism is operably associated with the capacitance sensor and with the valve for causing operation of the valve to be delayed for a selected period after the sensor has been operated and for limiting the number of operations of said valve per unit time.
