New research shows how a special tool called a noise logger can detect leaks accurately and efficiently, before major roadwork is required.
The world is approaching a water crisis. According to the International Water Management Institute, 33 per cent of the world’s population will experience water scarcity by 2025.
One main cause is leaks. Twenty to 30 per cent of treated water is lost in systems because of this simple and fixable problem.
Repairs need to be as precise as possible because excavation and resurfacing is a costly undertaking. Digging up more than one location, or more area than is needed for the repair, can lead to a problematic domino effect including traffic disruption, commuter frustration and loss of business.
Meanwhile, there are major public health risks associated with contaminants entering the water system through holes in pipes.
Luckily, researchers from Concordia University in Montreal have an innovative solution. In an article recently published by the American Society of Civil Engineers, Tarek Zayed, professor in the Department of Building, Civil and Environmental Engineering, shows how a special tool called a noise logger can detect leaks accurately and efficiently, before major roadwork is required.
Concordia University (commonly referred to as Concordia) is a Canadian public comprehensive university with campuses and facilities in Montreal, Quebec, Canada.
Founded in 1974 following the merger of Loyola College and Sir George Williams University, Concordia is one of the two universities in Montreal where English is the primary language of instruction. As of the 2011-2012 academic year, there were 45,954 students enrolled at Concordia, making the university among the largest in Canada by enrollment. The university has two campuses, set approximately seven km apart: Sir George Williams Campus in the downtown core of Montreal, in an area known as Quartier Concordia and Loyola Campus in the residential district of Notre-Dame-de-Grâce. With four faculties, a school of graduate studies and numerous colleges, centres and institutes, Concordia offers over 300 undergraduate and 100 graduate programs and courses.
The university was ranked 11th among Canada’s comprehensive universities in the Maclean’s 24th annual rankings. Internationally, Concordia was ranked 461-470th overall in the 2014 QS World University Rankings and is also included in Times Higher Education’s list of the top 100 universities worldwide under 50 years old. Nationally, the 2012 Higher Education Strategy Associates’ University Rankings placed Concordia 9th in the field of social science and 20th in science and engineering. The university’s John Molson School of Business is consistently ranked within the top ten Canadian business schools, and within the top 100 worldwide. Furthermore, Concordia was ranked 7th among Canadian and 229th among world universities in the International Professional Classification of Higher Education Institutions, a worldwide ranking compiled by the École des Mines de Paris that uses as its sole criterion the number of graduates occupying the rank of Chief Executive Officer at Fortune 500 companies.
Concordia is a non-sectarian and coeducational institution, with over 175,000 living alumni worldwide. The University is a member of the Association of Universities and Colleges of Canada, the International Association of Universities, the Association of Commonwealth Universities, the Canadian Association of Research Libraries, the Canadian University Society for Intercollegiate Debate as well as the Canadian Bureau for International Education and the Canadian University Press. The university’s varsity teams, known as the Stingers, compete in the Quebec Student Sport Federation of Canadian Interuniversity Sport.
