I am not sure where to post this but I need some advice and wanted to know if anyone knows anything about septic systems! We are buying a house that is in need of a new septic system. The sellers are paying for it and the septic guy suggests that the new system go to the front of the side of the house, there is a slight slope or hill, its not steep but that is where it most likely will go. When I mentioned this to someone they told me that is not a good idea because the tank can overflow if it is on a hill. But from my understanding from the septic person, the fields will be on the hill but the tank towards the backyard, which is flat. Does anyone know if the hill is a bad idea period? Also I heard that 'mound systems" are a bad idea, does anyone know anything on this subject? I want to make sure that we don't run into a problem with the location. Thanks!
