    You need to find a method to control the water electronically first. You can use a solenoid valve or a pump to control the water. What level of control are you wanting?

    Once you figure that out, you can create the circuit to drive it from a PIC.

    when tank is full it stop pump....one quarter full,buzzer on...a solenoid valve to control the flow of water going out... a pH sensor inside the tank...water level indicator
    i need a circuit to implement this and how to program the PIC 16F877A....
    any help will be very helpful...:confused:

    Okay, now you need buzzers and pH meters!? I think you need to define all of the behavior of your system.

    Draw out a block diagram of your system and we can work from there...

    a system indicating the water level in the tank...in parallel it stops the pump when water is full,when it is quarter full a buzzer is on...
    the pH in the tank,if water is too acidic or alkaline...
    a solenoid valve...controlling the flow out...if there is leakage,it closes.
    and if all these function can be displayed on an LCD....
    :confused:
