Abstract: A cable guide includes a substantially cylindrical pipe section with a substantially outwardly projecting flange at one end. A channel is formed in the outside surface of the pipe section and extends from a first point at one end of the cable guide to a second point at the other end of the pipe section and further extends through the flange. The two opposite ends of the channel are located at different positions around the circumference of the pipe section. The channel is sized and configured to provide a passage for accommodating a cable. The channel forms a ridge on the inside surface of the pipe section which is shaped so as to minimize the disturbance to the flow of waste water through the cable guide and, therefore, to decrease the likelihood of blockages occurring.

Abstract: A network and method of laying network cables in water supply pipes is disclosed. A building is situated near a roadway along which is laid a trunk cable. A water supply pipe branches off the water main to enter the building. A water supply pipe is provided at the time of construction of the building and is an underground pipe. It is conventional to provide a dedicated (and usually underground) conduit for a branch cable, which is expensive and disruptive. In the present invention the branch cable is laid along water supply pipe, enabling the cable to cross between the trunk cable and the building with minimal disturbance of the ground therebetween. This is achieved by introducing cable to pipe by use of a suitable Y-junction at location and removing the cable from the pipe by use of a second such Y-junction at location.
