This sounds unbelievable, I know - but it's true ... our next-door neighbours, 'till recently, fairly normal people, are actively flooding the foundations of the extension we're currently building. WHAT CAN WE DO???They are shoving a hose pipe into a gravel bed on their side of the garden wall and leaving the tap run and run and run. Our garden is lower than theirs and is flooding again and again and again. The builders are going spare! They've tested the water and have confirmed that it's treated, tap water, not rain water. They called the Council in, who also took a water sample, and have siad they'll meter next-door's water. The Council guy called to the house ref a 'suspected water leak out the back', but the neighbour told him he didn't know what he was talking about, and closed the door on his face,When we called to see the house last night, it was going on again, hosepipe jammed into wet gravel on their side of the wall - our site, dry on Friday afternoon was fill or water, and the 'lady' of the house was pottering about in her kitchen. (She's a solicitor, by the way!!).We called to the police station on the way home. They said they'd never heard the like - and told us to talk to the Council .... What's the best thing for us to do??(Neighbours objected to the PP, by the way, and appealed to ABP - lost out both times - but this is ridiculous!)
