Laying network cables in water supply pipes

摘要

A building (1) is situated in the vicinity of a public roadway (2) along which is laid a trunk cable (4). An individual property water supply pipe (6) branches off the water main to enter the building (1). A water supply pipe (6) is provided at the time of construction of the building (1) and is an underground pipe. It is conventional to provide a dedicated (and usually underground) conduit for a branch cable. This can however be expensive and disruptive. In the present invention the branch cable is laid along water supply pipe (6). This allows the cable to cross between the trunk cable (4) and the building (1) with minimal disturbance of the ground therebetween. This is achieved by introducing cable to pipe (6) by use of a suitable Y-junction (10) at location (10a) and removing the cable from the pipe (6) by use of a second such Y-junction (10) at location (10b).
