Ageing of water supply networks is a real problem which leads to leaks and bursts. A great challenge is to discover the state of degradation of the buried pipes. This paper describes the knowledge of Veolia Water – SADE of a non-destructive technology to inspect cast iron water pipes and the methodology developed to define its performance in terms of probability of detection of defects.

Acceleration Signals

The implementation of strategies for controlling water leaks is essential in order to reduce losses affecting distribution networks of drinking water. This paper focuses on leak detection by using vibration monitoring techniques. The long-term goal is the development of a system for automatic early detection of burst leaks in service pipes. An experimental campaign was started to measure vibrations transmitted along water pipes by real burst leaks occurring in actual water supply networks. The first experimental data were used for assessing the leak detection performance of a prototypal algorithm based on the calculation of the standard deviation of acceleration signals. The experimental campaign is here described and discussed. The proposed algorithm, enhanced by means of proper signal filtering techniques, was successfully tested on all monitored leaks, thus proving effective for leak detection purpose.

Operational Data

Abstract Daily exploitation of the water network, collecting of data concerning the failure of water pipes and knowledge of the repair team are the basis of the data used in the process of effectively removing and identifying failures. The paper proposes a methodology to identify the risk of failure of the water supply system that uses risk indexes according to the proposed three-stage scale of risk levels. An example of application methods for the actual operational data broken down by analysis and risk assessment for bus cables and a separate analysis for the distribution network.
