This is an old one I know but if anyone is out there...my neighbours fitted a sewage system when they were building their house.
It is sited near our boundary and runs loudly, in a very quiet neighbourhood, 24/7. The council are involved (again) after 8years of it and I am loosing hope that it will ever change.....I bought the house for its large garden, full of birds and native trees, hedgerows and flowers, but now watching bats in the evening or any sort of time of the day requires earplugs. The neighbours dislike me so any resolution will accelerate the disturbance I experience in other ways. Has anyone sued in court? Any advice would be helpful.
