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.
Qatar University (Arabic: جامعة قطر; transliterated: Jami’at Qatar) is a public university in Qatar, located on the northern outskirts of the capital Doha.
As of 2014, there are over 16,000 students. Courses are taught in Arabic (in education, arts and social sciences courses) or English (in natural sciences, engineering and business courses). The university is the only government university in the country. The university hosts seven colleges – Arts and Sciences, Business and Economics, Education, Engineering, Law, Sharia and Islamic Studies, and a College of Pharmacy – with a total of almost 8000 students at a 13:1 student-teacher ratio.
Students entering the university are placed in a “Foundation Program”, which ensures the acquirement of skills such as math, English, and computer technology.
Many of its academic departments have received or are currently under evaluation for accreditation from leading organizations. In addition to undergraduate academics, QU has a research infrastructure including research labs, an ocean vessel, technical equipment and a library housing thousands of books, including a collection of rare manuscripts.
The university serves on behalf of the government and private industry to conduct regional research, particularly in areas of the environment and energy technologies. Qatar University has a student body of fifty-two nationalities, 65% of which are Qatari nationals. About 35% are children of expats. Women make up approximately 70% of the student population, and are provided their own set of facilities and classrooms.
QU has an alumni body of over 30,000 graduates.
