Neighbor discharging sump water into our yard
Our neighbor has been battling water in their basement since we moved here. They were pumping water into a dry well to the front of their house. They've decided this isn't working and decided to drain out the back. They installed a perforated pipe running along side of our property line (about 6 ft from the line) and is buried about 18 inches down. It immediately started flooding in our yard. We've asked them to divert the flow and they have refused, saying this was their only option. I haven't been able to talk to anyone at the township office who can help me (we are in southern NJ). Is this even legal? I'd like to not go that route as we do need to live next to each other and our children our friends.
