Hi -- a quick couple of questions here regarding soil pipes. I'm digging the foundation for an extension as part of renovation work on an old house, and it's turned out that the soil pipe for the neighbour's house runs right down the middle of the trench for most of its length. I'm going to have to take it out; I'll put the new one in front of the trench, adding two shallow bends to get round the corner (I've okayed all this with the neighbour of course). I've not yet dug the trench to put it in.
The house as it currently exists has no plumbing. I'm not sure what the best course of action is for adding soil/waste pipes, or if there is a single best solution: Should I put junctions in the new soil pipe for the new kitchen, bathroom, and utility room that will be in the extension? Should I route them all into one section of pipe and join that to the new soil pipe? Should I route them into the existing inspection chamber (shown at the right in the drawings), which is a large concrete one with numerous unused entrances? Any advice you have would be great. The previous pipe setup was pretty ad hoc an chaotic so it's nice to have an opportunity to get everything in new, orderly, and accessible -- just not sure of the best way to go about it.
Here's a drawing of how it is currently, with the extension at the top:
