common ducting
More likely "dog in the manger" economics. It needs the utility regulators and local authorities to bang heads together and make the suppliers agree on a common wayleave type of system so they can use each other's ducts. At the moment they all want their own and no-one else in it, leaving our local pavements like some sort of mad quilting project. The road is those 1930s big concrete slabs, which they don't like going through, and they make a horlicks of the reinstatement when they do.
