Waste is where the waste is dumped to. Some have the benefit of a sloped yard, where they can put in piping going to the ground level and sending it out onto flowers or woods. Some install a sump pit with a sump pump that is used to pump the waste to some place higher than the previous. Some have tapped into their sanitary lines, not sure that that is legal, and some have sent it down storm drains. Determine where you want the waste to go, and then figure a way to get it there, either by gravity or by pump.
