For running communication cables to dwellings and other buildings to enable the distribution of information (e.g. in a cable television system) to or collection of information from those buildings, use is made of the pre-existing underground pipes which serve to drain sewage and/or surface and storm water away from those buildings. The cables preferably are secured to the surface of the sewage-draining pipes, preferably along the soffit of those pipes and for example by clips fixed at intervals. |
