HI
We are in the process of getting some plans drawn up for a 2.5 x 3m extension for the front of our house with a pitched roof. Unfortunately there is a foul sewer running along the front of our property (shallow, 100mm pipe) and this is adopted by Severn Trent Water (STW). Hence we are going through the process of applying to build over with STW.
The guy we have used to draw up the plans suggested that we replace the existing pipework and put a manhole either side of the build which seems fine. When he drew it for the STW application he put a bend in the foul sewer under the build because there is currently a manhole and a bend in that location. STW have rejected this and asked for the pipe to be straight under the build and then bend at the manhole cover outside the build.
Am I wrong in thinking that the architectural consultant should have known that putting a bend in the sewer pipe under the build would be a bad idea and rejected. He wants to charge us £200 to redraw the plans with a straight pipe for resubmission to STW which seems excessive.
I'm going to phone him this afternoon so any thoughts from more experienced people greatly appreciated.
Thanks
