Can i build over a mains water pipe? Can ypleas else help? I am putting an extension up on the side of a house, the ground is made up ground, so we are piling. As we dug the trenches, we uncovered a water mains pipe that feeds the cul-de-sac. It is definitely a mains pipe, cast iron, blue covering. It should not go through my clients property however, I think somebody has moved the boundary fence a while ago. I am looking to email Thames water to ask for their advice. My problem is; do I email them, and inform them? And then I get a resounding no and the an expensive quotation to move the pipe? ( any idea how much?) or keep quite and just build over it? Or build over it, protecting it, with a 18mm steel concrete brace? The customer is thinking about cancelling the contract. And finally, Should the architect have picked this up at the planning stage, as they have been granted full planning permission?
