Wavespeed measurement in buried water distribution pipes and its significance in leak location
(2013-09-16)
To determine the location of leaks in buried water pipes, acoustic methods are often used. These have proven to be very effective in metallic pipes but have been problematic in modern plastic pipes. In this paper the reason ...

Measurement of Wave Attenuation in Buried Plastic Water Distribution Pipes
(Assoc Mechanical Engineers Technicians Slovenia, 2014-05-01)
Leaks in pipes are a common issue encountered in the water industry. Acoustic methods are generally successful in finding and locating leaks in metallic pipes, however, they are less effective when applied to plastic pipes. ...
An investigation into the effects of resonances on the time delay estimate for leak detection in buried plastic water distribution pipes
(European Assoc Structural Dynamics, 2014-01-01)
In water distribution systems, old metallic pipes have been replaced by plastic pipes due to their deterioration over time. Although acoustic methods are effective in finding leaks in metallic pipes, they have been found ...

A stochastic model for the speed of leak noise propagation in plastic water pipes
(2021-06-09)
A good estimate of the speed of leak noise propagation is necessary to pinpoint the location of a leak using acoustic correlators. Models currently exist for this purpose, but they do not consider uncertainties in the pipe ...
On the Acoustic Filtering of the Pipe and Sensor in a Buried Plastic Water Pipe and its Effect on Leak Detection: An Experimental Investigation
(Mdpi Ag, 2014-03-01)
Acoustic techniques have been used for many years to find and locate leaks in buried water distribution systems. Hydrophones and accelerometers are typically used as sensors. Although geophones could be used as well, they ...
On the effects of soil properties on leak noise propagation in plastic water distribution pipes
(2018-08-04)
In many countries, leaks are located in water distribution pipes by using the cross-correlation of pipe vibration measured either side of a suspected leak. However, in modern plastic pipes this can be problematic due to ...
