im bidding on a job that needs drainage. the customer is getting an addition on in the back of the house and they have a ground water problem. the contractor doing the addition put in corregated pvc around the foundation (5ft deep) to help with the ground water from around the house that goes to a ditch where the pipe ends. the ditch is about 5 feet deep and is filled with water. i was thinking the attach the extisting pipe with pvc and run it into a dry well in the middle of the back yard then run it out the the round about 95 feet. my question is since the drainage pipe is 5 feet deep then the dry well would be around 5 feet deep also, if i put a pipe from the dry well ( 3 feet deep) will the water drain out to the road? i hope this makes sense!!!!! anyone have any other ideas???
