Abstract – This paper is focuses on detection of water leaks in pipe using fuzzy algorithm. In current correlation technique, it is employed to detect, position, and characterize the water leaks using the leak noise produced. But this technique is proved to be very efficient for only metallic pipes and this method is not true for plastic MDPE pipes. The leak noise signals are measured at two locations across the pipes. The speed of sound will be calculated with good accuracy and in this paper MDPE pipes are evaluated and it has been found that most of the leak signals are tested for MDPE pipes lie in the frequency band of 30 to 250 Hz with the upper frequency limit changes with flow rate ad leak characteristics.  In order to find the exact position of the water leaks in pipes, we use fuzzy algorithm. In this paper we can easily find the exact leak position in both metallic and Medium Density Polyethylene pipes (MDPE pipes).
