THE PRESENTED INVENTION IS CONCERNED WITH WATER CONSUMPTION SAVING THROUGH PERFORMING CERTAIN IMPROVEMENTS IN THE CISTERN MECHANISM IN ORDER TO PREVENT WATER LEAKAGE AND CONTROL THE WATER OUTPUT BASED ON REQUIREMENTS. THE NEW INVENTION INCLUDES THE USE OF AN ECCENTRIC WHEEL THAT PROVIDES COMPLETE CONTROL FOR THE FILLING VALVE. ALSO, IT PROVIDES HIGH CONTROL ON THE WATER LEVEL BY A SUPERFICIAL WHEEL THAT TURNS AROUND ITS VERTICAL AXIS IN TWO DIRECTION. ALSO, THERE IS AN ADDITIONAL CONTROL ON THE FLUSH VALVE TOGETHER WITH TWO CONTROL UNITS CONCERNED WITH THE FLUSH DISTANCE AND THE LEVEL OF THE EXCESS WATER
