A Multi-Level System utilizes the Enviro-Septic^® Leaching pipe by placing one leach area on top of the other, separated by a layer of sand.  This allows for twice the amount of leaching surface within the same area.

This procedure is used for areas with limited area for leach beds or problem sites that require a large amount of bacterial surface to treat high strength waste water.  Restaurants, laundry mats and other commercial operations may find this beneficial.
