Stone and pipe septicStone and Pipe Septic System

A stone and pipe effluent disposal area is the most common type of leach field.

Stone and systems have been around for many years and continue to be a popular choice that are backed by many engineers.  

The effluent disposal area is a bed of 1-1/2" septic stone which is laid on top of approximately 2'-3' of a suitable receiving layer (usually bank run sand).  Then 4" perforated septic pipe is laid out according to the state approved plans. Then an additional 4” layer of septic stone is applied followed by backfill, filter fabric, and loam.
