My neighbour has a smallholding of a few fields. The mains water supply crosses those fields. A secondary pipe is teed off this supply, then divides and one leg goes to their house, the other leg goes under our boundary wall to our house. The secondary pipe has sprung a leak on my neighbour's property. The leak is before both my neighbour's and our stopcocks. But it's not obvious whether the leak is on my neighbour's leg, our leg or the common feed, because we don't know the precise pipe layout to the nearest foot. The water supply people have told my neighbour it's his responsibility, although in the past they have repaired other leaks to the main supply pipe on his property. I've a feeling they have the secondary pipe designated as a 'private pipe' or some-such on their maps. AIUI many decades ago it was part of a private supply, before the water company put mains water into the area.
Main supply ____________________________________________ | | | secondary pipe | | | | < neighbours our house | X = stopcock my boundary wall < represents only a few feet, hence our uncertainty as to which < of our pipes is actually leaking. But that's not relevant IMO. <
But AIUI, the water company is responsible for the supply pipe up to the stopcock, whether that stopcock is out in the public road or some distance onto the owner's property, and surely they can't just absolve themselves of that responsibility simply because that's how they've got it shown on their maps. Is there an 'official' web site that gives chapter and verse on the division of responsibility between the householder and the water company for the supply pipe?
