“It’s about protecting the network by operating in a calm environment,” says consultant
An online training initiative designed to reduce human error in the way hydrants, valves and pumps are operated has now certified over 6,000 water network operators.
Aquam’s Calm Network Training, which is accredited by the Institute of Water, ensures that candidates achieve an understanding of the causes of transient surge in the water network.
Research shows that human error in how hydrants, valves and pumps are operated is a major cause of surge effects in water supply networks. Surge is a major cause of leaks and bursts in pipe infrastructure.
United Utilities (UU) was first to take up Aquam’s online Calm Network Training after launch of the scheme in 2014. The water company made it mandatory for its contractors to complete the course, which involves a video tutorial and multiple-choice assessment. Over 3,000 operators of UU’s potable water network have achieved certification to date.
Severn Trent Water has also made Calm Network Training mandatory and has trained over 1,600 users of its networks. Eight other UK utilities have also taken advantage of the comprehensive and flexible training programme.
Beyond reducing surges, the benefits of the training can include increased lifespan of existing infrastructure, reduced leakage and water wastage, fewer incidents of discolouration and contamination of the water supply caused by ingress, and fewer customer complaints about leakage, water quality and supply interruptions.
Aquam consultant Roman Boryslawskyj said: “The good news is that much of the harm done to pipe infrastructure can be avoided by modifying the way the network is operated. This can be achieved by ensuring operators are thoroughly trained, which utilities must do under their duty of care.
“It’s about protecting the network by operating in a calm environment; then you don’t disrupt customers. Each burst attracts an average of 35 complaints and costs £1,000 a time – and that’s just an average cost.”
