Circuit Diagram of water level indicator

How do it working 

When water level being lowers most point then blue led is glow. And water reaches to medium point then yellow led is glow, similarly when water level reaches to top most point then red led is glow that means water tank is full. In this condition circuit with buzzer gets completed and buzzer starts beeping.
