A pipe network for supplying a utility to a multitude of service connections includes a plurality of acoustic sensors mounted at the service connections. The acoustic sensors are preferably integrated in ultrasonic flow meters. The method comprises the steps of obtaining information about a time of change of a fluid pressure and then establishing a first noise indicator from the noise measured by the acoustic sensors before said time of change, establishing a second noise indicator from the noise measured after said time of change; and then correlating one or more first noise indicators and second noise indicators with the fluid pressure to identify service connections subject to leak indications. A leak detection system based on a mathematical cross correlation of noise indicators and fluid pressure in a fluid pipe system is also described.
