Hi all, I have been battling with my local water authority with some ground movement problems next to a manhole. I have had builder round insists its a drainage issue causing the movement of the ground (water board responsibility). water board say they've been out, cleared the drains and inspected with cctv, they are all fine and the issue is nothing to do with them. I have since lifted the manhole and I am no expert but they look poor and its conceivable that the manhole could be the issue. I would like some opinions from people who know far more than me about drains so I am armed with some correct information when I call the water board.
