A Multi-Level System utilizes the Enviro-Septic Leaching pipe by placing one leach area on top of the other, seperated 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.
During the winter months Presby Environmental, Inc. conducts training classes for installers, designers, plumbing code inspectors, code enforcement officers, and realtors to train them in the installation and design of these Multi-Level Systems.
