Tutorial - Leach Fields & Beds
Leach Fields and Beds
These disposal systems include a shallow bed of leach stone, about 1-ft thick, with a network of perforated pipes installed in the top of the leach stone. A layer of peastone is placed over the entire bed to prevent topsoil from mixing into the leach stone.
Pictures show a leach field under construction and a finished leach field without cover soils. Pea-stone is applied over the top of the leach stone to prevent soil from plugging the leaching system.
