Parents have a building that used to be a cottage on their property. It's right on the waterfront and their house is up hill from that. Anyways it has a septic field and we are finishing the inside to make a guest house/apartment. We need to run a line uphill from that building and tie it into the main sewer line for the property. I'm thinking we will need a transfer pump to move fluid up the hill? Also wondering if a ditch witch? would dig deep enough to run that type of pipe? What type of pump if I need it would I look for? And anyone know what that type of job bills like? By the foot?
