I leave in a neighborhood and my house is located at the bottom of a hill. When it rains i catch all the water from my neighbors. I have french drains all over the yard, but whenever I have a sudden downpour they become flooded with water. My house in situated beside a major roadway with a drainage ditch in between my house and the roadway that feeds into one of the concrete manholes. I am considering a pump buried in some large stones that would run about 150ft to the drainage ditch on side of the road. What exactly would anyone recommend such as pump and pipe size?
