Water companies are regulating discovering rods to find subterraneous pipes notwithstanding there being no systematic justification they work, an Oxford University scientist found.
Sally Le Page pronounced her relatives were astounded when a technician used dual “bent tent pegs” to find a mains pipe.
She contacted all a UK’s H2O companies, and a infancy reliable engineers still use a centuries-old technique.
However, a series pronounced a apparatus was not standard-issue equipment.
The routine of regulating discovering rods, also famous as dowsing, has been in use for hundreds of years.
A dowser will typically reason a rods, customarily made like a minute Y, while walking over land and being warning for any transformation to find water.
Evolutionary biologist Ms Le Page, whose relatives live in Stratford-upon-Avon, first contacted Severn Trent Water around Twitter.
It replied: “We’ve found that some of a comparison methods are only as effective than a new ones, though we do use drones as well, and now satellites.”
Other companies that gave a identical response were:
- Anglian Water
- Thames Water
- Scottish Water
- Southern Water
- Welsh Water
- United Utilities
- Yorkshire Water
Ms Le Page said: “I can’t state this enough: there is no scientifically rigorous, doubly blind justification that discovering rods work.
“Isn’t it a bit stupid that large companies are still regulating sorcery to do their jobs?”
In a matter released later, Severn Trent said: “We don’t emanate discovering rods though we trust some of a engineers use them.”
All a companies emphasised they do not inspire a use of discovering rods nor emanate them to engineers, and pronounced complicated methods such as drones and listening inclination were preferred.
Northern Ireland Water, Northumbrian Water, South West Water and Wessex Water pronounced their engineers do not use them.
