alternative systems, such as a mound, low pressure pipe, or at-grade system, as well
as conventional system.
Distribution Box
A watertight chamber below the outlet level of a septic tank or treatment unit and from
which effluent enters the absorption system.
Domestic Sewage
Sewage which is normally characterized as and is similar to residential wastewater, not
commercial or industrial activity, and which originates primarily from kitchen, bathroom,

such similar type of work as designated by the Director of the Johnson County
Environmental Department or her designee.
