Primayer’s collaboration with Anglian Water continues to reduce leakage
The joint project between Primayer and Anglian Water has seen leakage reduction of 1.4 million litres of water per day in targeted areas. Anglian Water is now well set up to meet and most probably exceed Ofwat’s tough leakage targets for the AMP7 investment period 2020-2025. One of the biggest challenges facing water companies is finding leaks in non-metallic pipes and over long distances. Primayer’s new hydrophone sensor in the Enigma3hyQ noise correlator can detect and pinpoint leaks in plastic pipes up to 4.6m away.
This development has been called a game changer by Anglian Water’s smart water strategy manager Andy Smith, who said it would “revolutionise what we do”. 3,500 correlators are now being rolled-out across Anglian’s whole network, another 1,000 will follow. The 2,035 correlators currently installed have identified 1,600 potential leak locations, which have converted into 1,325 actual leaks. This represents a conversion rate of 83%, which is exceptionally high.
Richard Fielding, hydraulic optimisation engineer at Anglian Water, said: “The consistent performance from the Enigma3hyQ is enabling us to make a real step-change in how we manage leakage. In addition to locating previously undetectable leaks on plastic pipes, we are improving the service we provide our customers by detecting and repairing leaks before they become visible.
“The permanent nature of this technology also increases our efficiency by allowing us to prioritise the deployment of our detection teams to the parts of our network with the highest need, resulting in reduced travel time, increased productivity and a reduction of the associated health and safety risks of routine leakage detection surveys.”
