PIPE ROVER & LEAK DETECTION PROGRAM
Leak detection and managing water losses – as well as pipe integrity - are of significant interest to the industry. A range of solutions are being considered for application. Dean Barnett from Western Water is the program leader.
New Technology calling
A 2017 program is being developed and an invite any technology provider that are interested in participating in an IWN trial to contact Dean Barnett.
Echologics - ePulse. This technology uses noise within pipelines to conduct pipe integrity testing.
UVS - SewerSerpent IWN trial. This technology can diagnose leaks within the sewer network up to 225mm diameter.

Concrete sewer pipe testing – in development
IWN is partnering with Latrobe University to develop a concrete sewer pipe tester to analyse H2S damage and determine the remaining life for pipelines up to 300mm diameter.
A prototype was field tested in February. Testing of the prototype version 2 is expected to be undertaken in June 2017.
WIOA Victorian Network Operators Development Program
A new WIOA Victorian Water Industry Network Operators Development Program is being developed by a steering committee. This will result in a WIOA Network Operator Development Program and one Network Operator of the Year Award. The Water Distribution Program now has a section on the IWN Pipe Rover & Leak Detection program and IWN structure.
Pipescan+ - trial completed
Pipescan+ is a device that can be manually fed into a live water main to assess pipe integrity. While not currently recommended for ongoing application, recommendations have been made for future development of the technology and IWN are hopeful of conducting trials of the improved technology in the future.
p-CAT – trial completed
Transient pressure wave technology developed by the University of Adelaide enables non-invasive diagnosis of pipeline condition over long distances. The trial recommendation is that p-CAT is suitable as a business as usual tool for pipe condition assessment with support technologies to pinpoint pipe integrity issues.
Satellite leak detection - trial completed
This trial used satellite technology developed to find water on other planets. Because drinking water has a particular spectral signature, the system can use geological, meteorological and hydrological factors to indicate leaks underground.
The first trial commenced in late 2015 with a second trial conducted in late 2016. The satellite technology successfully identified a number of leaks across an area of more than 3000 square kms of both regional and metropolitan areas. Whilst improvements to the technology had been made between the two trials, the second trial report identified more work was required to improve the accuracy of the technology in Victoria.
A second trial of this technology commenced in later 2016 and looking at infrastructure in the CBD and regional locations. The report for this trial is being finalised.
Investigations are underway with other potential providers.
