Abstract: “It has been noted that water crisis are reaching at alarming proportion in Pakistan, due to miss management and low literacy rate. Most of households use water pump to get fresh ground water and fill there overhead tanks, but due to less technical involvement enormous amount of the water is wasted. Automatic water control system provides significant solution to this issue. Methodology of this system is all depend on the electric conductivity of water and logical signals given to different logic gates. This system terminates the water pump from over flow and also shows indication at different levels of water in overhead tank.”
