At the other house we paid about £350 5 years ago. There are 4 houses on our complex one septic tank next to the gate feeds 2 houses the manhole is less than 3 metres from it, they refused to put a pipe in as they only do one feed per complex, so he said they would take all our paving up approx 50m to feed into the mains from the other gate, and of course nothing goes back correctly Bonkers
