Following on from my salt glazed pipe thread this one should be interesting. My negotiation with the water company didn't go very well. They are happy with the size of the inspection chamber being 600 x 450 as opposed to the monster specified needlessly on my design drawings.
My problem is they will under no circumstances countenance plastic being on the main drain run. I can either go brick built or precast concrete and I think the 300mm deep 600 x 450 sections may be just about managable with some help at 80kg or so.
So, how the hell do I form a new inspection chamber with all the required benching and pipe connections whilst having a live sewer running through the space I'm going to be working in. Does anyone have any experience in doing such a job? I'd love some guidance.
