A flush water control arrangement includes a water control pusher alignedly extended towards a flushing shaft, and an automated actuation unit which includes a motorized unit and an automated plunger arm movably extended towards the water control pusher. When the motorized unit is activated in responsive to a presence of a user, the automated plunger arm is driven by the motorized unit to move the water control pusher so as to actuate the flushing shaft between the first and second positions for complete a flushing operation. The water control pusher is actuated to push at the second position of the flushing shaft to complete the flushing operation with a relatively high volume of water. The water control pusher is actuated to push at the first position of the flushing shaft to complete the flushing operation with a relatively low volume of water.
