The mound septic system was originally developed in the 1940s in North Dakota. Known as the “NODAK disposal system”, it was designed in response to the state’s harsh climate and variable site conditions. This septic system featured a septic tank that pumped wastewater to an above-ground gravel mound with distribution pipes running its length and width. The concept is still used today in places with especially slow or fast permeable soils, shallow soils over porous rock, or a high-water table.
