After running 140 feet of main line back to the house from the street at a depth of around ten feet, a second line to the new house is going in the same trench at a depth of about five feet. I am six days into this "one day job" so far. Toward the back of the property we found solid table rock some 4 feet down. Some times you wish you had never opened "that can of worms". Why go to the National when you could be doing this ?
