Three separate water leaks located over a distance of 826m using the AQUASCAN TM2 - Case Study
Introduction Locating leaks on large diameter water mains can be very difficult due to poor sound propagation and increased distances between fittings that can be used to perform correlations from. For a correlator to highlight a potential leak each sensor must be able to receive the signal from that leak. Once a correlation is highlighted it is then down to the software and the user of the ...

Pipeminder-S & Cobb County Marietta Water Authority Case Study
Cobb County Marietta Water Authority (CCMWA) has a large diameter transmission main loop carrying water around its jurisdiction. The loop is 75 miles long, with pipe diameters of 36 to 54-inch diameter and consists of both ductile and PCCP material. Undertaking condition assessment inspections or installing a typical leak detection monitoring system for the full length of the line was deemed cost ...

Counting the Drops: Leak Detection and Auditing Methods for Property Managers
Leaks are never good, whether it’s a leaky boat or a leaky pipe system. Even advanced water utility systems can experience water loses ranging from 10 – 40%, with these losses being proportional to the population of the urban area serviced by the water distribution system. Large cities like New York, Chicago, and Los Angeles are vulnerable to staggering amounts of water loss in ...

Pipeline infrastructure renewal at Miami-Dade Water & Sewer Department
Abstract Various governmental, professional and private studies have shown that the replacement costs of underground pipeline infrastructure is excessive and that best practice approaches for infrastructure risk management promote condition assessment programs to understand the actual condition of individual pipe sections in order to best allocate limited capital replacement and rehabilitation ...

Good Risk Prioritization Puts City Of Saskatoon On Top Of Its Game
While pipeline management may seem unaffordable, understanding the condition and targeting repair provides an alternate approach to wholesale replacement and allows operators to accomplish the same de-risking effort with less money. The City of Saskatoon operates more than 100 kilometers of water mains (400 mm diameter and larger) within the Water and Sewer Preservation Group. The City has an ...

Tackling Non-Revenue Water by Identifying Small Leaks
Small leaks sink big ships – the same can be said for large-diameter pipes in utility networks. While large leaks or ruptures are seen as newsworthy stories accompanied by images of water flowing down the streets; smaller leaks can often be more devastating. Left undetected, they can add up over time, contributing significantly to Non-Revenue Water, and eventually, they too can lead to ...

For Malaysia Water Operator, NRW Leak Detection Program Recognized As Major Success
At Singapore International Water Week 2016, one of Pure's licencees presented a poster on two acoustic-based technologies (tethered Sahara® and free-swimming SmartBall®) used to locate 674 leaks on large-diameter trunk mains operated by this Malaysia water operator. Conducted over four months, the in-line inspection and resulting repairs has saved total of 46.7 million liters of water ...

Small leaks matter
In the final part of the leak detection series, we explain why locating small leaks is and important part of a water loss management strategy. To see the first post in the series that outlines the problem of water loss in North America, click here. Many leak detection programs have a mandate to save the most water and focus on locating and repairing large leaks in favor of small leaks. However, ...

Hole Dug, Leak Found - City Of Ottawa Entrusts Smartball Platform To Look For Leaks In Tranmsission Main
When your inspection task is to survey a critical pipeline for leaks, nothing is more satisfying than trusting your technology to predict the leak location and then standing by as the client excavates the area to find a flow of water within one meter of exactly where you said it would be. The above-described "leak-where-predicted" recently happened with the City of Ottawa, when Pure Technologies ...

Leaks on large-diameter trunk mains – more than just non-revenue water reduction
Providing safe, reliable access to clean water is a major challenge for utilities around the world considering that roughly 12 billion gallons of water are lost every day globally. While many utilities are aware of the importance of reducing Non-Revenue Water (NRW), reducing it can be a challenge. The World Bank estimates that NRW costs utilities worldwide about US$14 billion every year. By ...
