Hi J,
I recently went through the whole processes with WW. Our extension was being built near, but not over the shared sewer which also ran parallel to the rear of our property / extension.
They wanted the same for me, also to inspect works to the sewer as we progressed. They were pretty rigid with what they wanted, and also insisted on a survey of the sewers on the highway as we planned to build a porch too; turned out these sewers were over 7 metres from our build but I was still required to fork out for this.
My engineers drawings included ground beams and pad foundations in sections to avoid pressure over the sewer line and we shifted an inspection chamber 400mm back away from the extension.
I hindsight, I think it would have been easier to just apply to have the sewer diverted, moving it further away from the extension. We could have then gone with traditional foundations and the whole build would have been a lot smoother.
