The 'Leakfrog' is expected to boost Thames Water's programme of leakage reduction, by detecting the amount of water escaping from customers' pipes - which accounts for around 25% of all water lost in Thames Water's supply area.
Once installed on a domestic circuit, Leakfrog measures the time between pulses on a meter which allows Thames Water to calculate how much water is being used.
"Around 170 million litres a day is actually lost from pipe work belonging to customers. Until now, this water loss has been extremely difficult to pinpoint and account for." said Thames Water's Director of Water Services, John Halsall.
"Now, with Leakfrog we can get a better idea of how much water is leaking from the customer's side. Leaks are not only an unnecessary waste of water, but left undetected can add hundreds of pounds to bills and cause damage to the property," he added.
Developed in partnership between Thames and Qonnectis, Leakfrog is a cost effective and network wide solution where hitherto leakage detection devices in use have been bulk and difficult to attach to a water meter and complicated to use.
"The frogs have been specially designed so that they can be easily fitted, in large numbers, to our meters, and they tell us if a leak is present, something our previous methods haven't been able to do on such a large scale," said Leakfrog inventor Nic Clay-Michael, a special projects manager at Thames Water.
