If you had to work out where to dig so that you didn’t cut off the water supply to an entire town, would you rely on a Ouija board for your answer? Probably not, but that is in effect what at least two UK water companies (now ten out of the twelve UK companies, see update below) openly admit to doing in 2017. Except instead of asking a Ouija board, they are asking divining (or dowsing) rods.
My parents were trying to install a new water pipe from the mains, which required knowing where the existing mains water pipes were underground. After calling out a technician from Severn Trent, the water company that services the whole of the Midlands, my parents couldn’t believe their eyes when they saw the man from Severn Trent slowly walking around holding two “bent tent pegs” to locate the pipe.
