592205 A building is situated in the vicinity of a592205 A building is situated in the vicinity of a public roadway along which is laid a trunk cable. public roadway along which is laid a trunk cable. An individual property water supply pipe branches An individual property water supply pipe branches off the water main to enter the building. The wat off the water main to enter the building. The water supply pipe is provided at the time of construcer supply pipe is provided at the time of construction of the building and is an underground pipe. Ition of the building and is an underground pipe. It is conventional to provide a dedicated (and usuat is conventional to provide a dedicated (and usually underground) conduit for a branch cable. This lly underground) conduit for a branch cable. This can however be expensive and disruptive. As disclocan however be expensive and disruptive. As disclosed herein, the branch cable is introduced into thsed herein, the branch cable is introduced into the pre-existing pipe. This allows the cable to crose pre-existing pipe. This allows the cable to cross between the trunk cable and the building with mis between the trunk cable and the building with minimal disturbance of the ground therebetween. Thisnimal disturbance of the ground therebetween. This is achieved by introducing cable to the pre-exist is achieved by introducing cable to the pre-existing pipe (6a, 6b) along a microduct tube (18a, 18bing pipe (6a, 6b) along a microduct tube (18a, 18b) by use of a suitable Y-junction (11, 12, 13). On) by use of a suitable Y-junction (11, 12, 13). One arm (12) of the Y-junction is adapted to be conne arm (12) of the Y-junction is adapted to be connected to the pre-existing pipe, and another arm (1ected to the pre-existing pipe, and another arm (13) of the Y-junction is capped with an end closure3) of the Y-junction is capped with an end closure (15) having a cable passage (16) provided thereth (15) having a cable passage (16) provided therethrough, the cable passage being adapted to allow through, the cable passage being adapted to allow the passage of the microduct tube but prevent the pae passage of the microduct tube but prevent the passage of water alongside the microduct tube. ssage of water alongside the microduct tube.
