Unitywater (QLD) is seeking technology based services to identify leakage in their trunk water main network infrastructure.
Unitywater maintain and operate more than $3.1billion in water and sewage infrastructure in Queensland. If water loss through leakage occurs, it can be a significant and costly problem.
An Expression of Interest (EOI) has been released to the market to find a solution that can monitor a large portion of the water trunk network and identify sites of leakage or potential leakage.
Unitywater has previously trialled technologies that include a tool which travelled through mains detecting leaks, unmanned aerial vehicles fitted with high definition colour and thermal cameras, and pipeline frequency injection leakage detectors.
Some of these techniques may still be used in the future, however Unitywater is searching for a broader solution.
Unitywater’s trunk main pipes range from 300mm in diameter to 1,500mm and make up 910km (16 per cent) of the water network.
Any leakage detection system operating on the trunk mains network must be repeatable and cause little or no impact on the day-to-day operations of the water supply network.
The expression of interest is performance based, with no preferred or methodology, and is open to hearing from both local and international providers.
Unitywater provides water supply and sewerage services to Moreton Bay, Noosa and Sunshine Coast residential and business customers in Queensland.
Unitywater has more than 5,731km of water mains, spread over a large geographical area and with a diverse range of pipe sizes, materials and ages, which is why they wish to reduce costs and increase operational efficiency through innovative, efficient methods of non-destructive, leak detection on trunk water mains.
The EOI submissions close 29 January 2016. For more information on the submission process contact [email protected].
