Supply and disposal pipe system between buildings and e.g. sewage system consists of concrete jacket tub containing various supply pipes and sewage/waste water pipes

摘要

Various supply pipes (3,4,5,6) are contained at least partially in a concrete jacket tube (1), which also contains a sewage pipe (7) and/or a waste water pipe (8). The jacket tube extends from a building, and may be formed as a sewage pipe, which extends to an inspection shaft of a sewage channel. The supply pipes are located above the expected water level within the tube and extend to the inspection shaft, and from there within a branch pipe to the main supply lines.
