stone bed disposal area acts as an underground retention and final
treatment area for effluent. Crushed stone 3/4 to 2 1/2 inches in
diameter is used in the construction of a bed. Sizing disposal beds is
accomplished by multiplying the design volume of wastewater, (expressed
in gallons per day) by the size rating parameter determined by the soil
profile classification. This bed provides a void space for the storage
of effluent and to allow it to drain into the surrounding soil. The
Subsurface Wastewater Disposal Rules require distribution piping
within all stone disposal areas (beds and trenches). The purpose is to
provide for an even distribution of effluent (as practical) throughout
the disposal area(s). We typically sell 4" schedule 20 perforated pipe
for distribution piping.
