Études expérimentales en laboratoire et in situ de la relation entre la pression et le débit de fuite dans les réseaux d'eau potable

Abstract

Water loss through leaks are practically inevitable in drinking water distribution systems. For municipalities, reducing water losses at an optimum level thus becomes a priority to contribute for sustainable and integrated water resources management and to provide water at affordable cost. Most solutions that can be implemented to reduce water losses through leaks at an optimum level are generally known and applied through a certain level within Québec municipalities. However, proactive pressure management remains an underdeveloped solution at the present time since its recent international expansion and its limited broadcast in Québec, particularly for the relationship between pressure and leak flow. The objective of this master thesis is to analyze and validate, with laboratory and in situ experimental studies, the relationship between pressure and the leak flow. The laboratory setup allowed carrying out tests and uncertainty analysis in a controlled environment while the municipal water distribution system was allowed to validate the results in situ. Laboratory and in situ experimental studies results are near those recognized internationally. However, uncertainty analysis demonstrates acceptable errors for the laboratory experimental study, but very significant ones for the in situ experimental study given the lack of water consumption metering.
