  • Leakage–pressure relationship and leakage detection in intermittent water distribution systems

    Field investigations were conducted to identify the relationship between leakage rate and pressure in selected areas of the water distribution system of the Holy City of Makkah, Saudi Arabia. Noise correlators were used to detect leaks in areas where the water leakage exceeded 20% of the total water supplied. The leakage rate was found to be related to pressure raised to the nth power. The value ...
