Gravelfilled absorption beds are constructed in the sand fill, and effluent from a Mound Septic System design, install, maintain, repair: this document discusses the use of septic mound systems as an alternative septic system design. A septic mound is an engineered system involving fill to create a soil absorption system for the disposal of septic effluent.
Fig. 1. Schematic of the Wisconsin mound system showing septic tank, dosing and mound. dosing chamber contains a pump or siphon, which transfers effluent, under pressure, to a distribution network of small diameter pipes with small perforations which distributes the effluent uniformly over the absorption area of the mound.
septic tank and a subsurface soil absorption system with nonuniform distribution of the effluent to subsurface soil trenches or an absorption bed. Cover Material: The material used to cover a mound system, usually selected on its Mound Septic System Your mound is a drainfield that is raised above the natural soil surface, primarily built of sand.
Within the sand fill is a gravelfilled bed with a 2inch pipe to receive and distribute effluent, and are covered with native or imported top soil to allow vegetation to be planted. Technologies explored in the 1980 manual include the conventional system (a septic tank with a subsurface wastewater infiltration system), alternating leach fields, uniform distribution systems, intermittent sand filters, aerobic units, disinfection technologies, and evapotranspiration systems.

Check the pump chamber, pump, and entering the mound system. 3. Protect the mound from overloading after a prolonged power outage or pump during the first manual switching.
