he
distribution box (D-Box) is located in or just before the disposal
field. A D-Box is a small tank that has one inlet and multiple outlets
that uniformly disperse the flow of the effluent to several lines of a
disposal field. A D-Box is very useful when inspecting a failing
disposal field to determine possible problems within the system.
In the cold winter months where there is no protective snow cover,
freezing can be a problem for the D-Box. Some methods to help prevent
freeze-up would be to either provide a layer of insulation over the
D-Box cover, or to connect the effluent line to a bottom inlet.
