Development of a long duration, free swimming, inline acoustic leak detection inspection tool
Abstract Acoustic leak detection inspection tools have become a common technique to identify minute pipeline leakage before the leak and the defect producing it can become a larger problem or even a rupture level event. While these inspection tools only identify small defects once they reach the through wall stage and result in leakage, they can be an effective means of demonstrating the ...

Device combines pressure monitoring with acoustic leak detection
In the world of municipal water and sewer maintenance, leaks are money. Not only does that mean money down the drain, but technically right out the drain as well. Those additional treatment and conveyance costs mean not only decreased revenue, but also increased costs in leak detection and pipeline repair. To combat the issue, Syrinix has launched the PIPEMINDER-ONE Acoustic, a device that ...

Wastewater force main management – internal corrosion survey using inline methods
In our first post about Wastewater Force Main Management, we looked at how preliminary analysis helps operators develop a plan for managing their system. After completing this process, operators can begin putting the plan into action with preliminary surveys on specific force mains. For those at WEFTEC, you can visit Pure Technologies at Booth #1382 to find out more information on successful ...

Who does water actually belong to? - Pipe location for tracking down theft of water in Peru - Case Study
Water makes you important Water is nowadays such a precious commodity that some countries which in fact already have too little drinking water for their own demands are selling rights to water sources to international companies or are even exporting water they desperately need themselves. The better the water supply functions in a country, the lower the risk of a drinking water shortage ...

Successful trunk main correlations in Australia, the land of long pipes - Case study
The Aquasscan TM Successfully locates leaks at distances over 1KM in Sydney. The Gutermann Aquascan (Trunk Main) correlator provided a series of high performance correlations in trials performed in Sydney, Australia. Sydney Water provided a 1.2 KM of 600mm OD Steel trunk main for a series of tests to be performed to evaluate the performance. The testing was administered by Veolia Water & ...

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 ...

Distributed Thermal-Acoustic Data Integration
Silixa has developed a technique called Distributed Thermal Acoustics (DTA) to monitor simultaneously the thermal and acoustic profile along a hybrid optical fibre cable in submarine environments. Using its world leading distributed fibre optic technology (ULTIMATM DTS and iDASTM) Silixa deployed an optical fibre cable along the seabed and across the water column in an active gas seepage field. ...

Is zero leakage becoming an attainable goal?
As Ofwat prepares its draft methodology for AMP8, FIDO CEO Victoria Edwards asks if it’s possible to replicate the UK’s past leaps in leakage performance without a game-changing leap in technology. In 2018, the UK’s National Infrastructure Commission called on water companies in England and Wales to halve leakage to protect long term water supplies. That means reducing ...

Condition assessment program continues in North Queensland
Justification of an ongoing condition assessment program can, at times, be difficult for water utilities. However, successful inspections that deliver actionable outcomes on how to manage aging assets make this justification much easier. Certainly that was the case for Mackay Regional Council (MRC) when it engaged the services of Pure Technologies (Pure) to conduct a variety of condition ...

Modified log-normal particle size distribution in acoustic spectroscopy
The modified log-normal distribution is a smooth continuous distribution depending on four parameters: median size, standard deviation, minimum size and maximum size. This distribution introduced by Kottler [J. Franklin Inst. 250 (1950) 339] and Irani [J. Phys. Chem. 63 (1959) 1603] gives an opportunity to restrict the particle size range. This distribution is asymmetrical on the logarithmic ...
