Belfast Water came on Wednesday morning. The had used a metal detector and an acoustic sensor and heard hissing under the road so they dug up a section. The pipe was not there. They used an instrument that put a signal in the metal pipe and a sensor to locate the signal. This put the pipe under the ditch. It was some 8-9 feet deep which is why the metal detector didn't pick it up. The patch was completed by the afternoon and they filled in their holes and used the backhoe to pack it down. Later they will patch the road.
