Sniffer dog trained to detect burst water pipes
For the first time a sniffer dog has been trained to detect water leaks and could be used to track down burst pipes in the future.
Snipe, a 16-month-old cocker spaniel, has undergone weeks of training by ex-military personnel to detect problem pipes by sniffing out tiny amounts of chlorine in tap water.
The dog has now been recruited by United Utilities (UU), which supplies around three million homes in the North West of England, in a UK first for dog leak detection.
Snipe will be used in trials to assess if his sniffing skills can pinpoint water being wasted in rural areas where leaks are hard to detect.
Owner Ross Stephenson, 32, the MD of Cape SPC, a pest extermination expert firm in Liverpool, has been putting Snipe through his paces since late last year.
He said: “All I did was start off with normal tap water, and then putting in extra chlorine levels to make it stronger.
“So we just put a tiny bit of that in, so the dog understands the strongest odour is the one we want them to find.
“We would have eight glass pots; one of them will have it in and every time the dog sniffs that pot he will get rewarded - a tennis ball.
“What I had to do was take the pots outside first and start doing it in different environments and then I would take the pots away and then ended up having normal tap water, pouring it on the ground and getting the dog to search that.
“So we want the dog to sit and stand and stare where the source is, so try to get the dog to stay there for 30 seconds: a ‘passive indication’.”
Stephenson, from Bristol, set up his firm after leaving the military two years ago, where he served with the Royal Veterinary Corps as a Corporal, deploying to war-torn Afghanistan and Iraq.
His business partner Luke Jones, 27, from Bargoed, south Wales, served in the same military unit, using dogs to search for weapons, explosives and IEDs before transferring his skills to teach dogs to sniff out bed bugs - and now detecting water leaks.
Jones added: “All the principles are basically exactly the same, it’s just a different setting. And less stress.”
UU, responsible for a network of 42,000 kilometres of pipes, fixes around 27,000 leaks a year, with a team of 140 personnel, using high-tech drones, camera and sound detection equipment – and now their new recruit Snipe.
Tap water contains one part chlorine per million parts water, with a dog’s nose calculated as being able to detect one particle of an odour or scent in a billion.
In December the Consumer Council for Water said that England and Wales lost 3.1 billion litres of water every day from leakage.
