Specific words and phrases. As used in this chapter,
the following terms shall have the meanings indicated:
EFFLUENT
Liquid flowing from any sewage treatment device, such as
a septic tank.
FLOODPLAIN FRINGE
Those floodplains excepting the floodway subject to inundation
by the one-hundred-year recurrence interval flood.
FLOODPLAINS
For the purpose of this chapter, the floodplains are all
lands contained in the regional flood or one-hundred-year recurrence
interval flood.
FLOOD PROFILE
A graph showing the relationship of the floodwater surface
elevation of a flood event of a specified recurrence interval to the
stream bed and other significant natural and man-made features along
a stream.
FLOODWAY
A designated portion of the one-hundred-year flood that will
safely convey the regulatory flood discharge with small, acceptable
upstream and downstream stage increases, limited in Wisconsin to 0.1
feet unless special legal measures are provided. The floodway, which
includes the channel, is that portion of the floodplain not suited
for human habitation. All fill, structures and other development that
would impair floodwater conveyance by adversely increasing flood stages
or velocities or would itself be subject to flood damage should be
prohibited in the floodway.
HIGH-WATER ELEVATION
The average annual high-water level of a pond, stream, lake,
flowage or wetland referred to an established datum plane or, where
such elevation is not available, the elevation of the line up to which
the presence of the water is so frequent as to leave a distinct mark
by erosion, change in or destruction of vegetation or other easily
recognized topographic, geologic or vegetative characteristics.
HOLDING TANK
Any facility designed to be watertight, which is used for
the storage and decomposition of human excrement, domestic wastes
or liquid industrial wastes.
NATURAL UNDISTURBED SURFACE
The state of the soil or a test site without grading or filling
of a site. Stockpiles of topsoil set aside for future use, for example,
are not soils in their natural, undisturbed surface.
NAVIGABLE STREAMS
Any stream which is capable of floating any boat, skiff or
canoe of the shallowest draft used for recreation purposes.
NUISANCE
Any source of filth or cause of sickness within the meaning
of Ch. 146, Wis. Stats.
PORTABLE TOILET
Fixtures incorporating holding facilities designed to receive
human excrement directly from the user and which are transportable.
PRIVATE SEWAGE SYSTEM
A sewage treatment and disposal system serving a single structure
with a septic tank and soil absorption field located on the same parcel
as the structure; an alternative sewage system approved by the Department,
including a substitute for the septic tank or soil absorption field,
a holding tank, a system serving more than one structure or a system
located on a different parcel than the structure; and may be owned
by the property owner or by a special purpose district.
REGIONAL FLOOD
A flood determined to be representative of large floods known
to have generally occurred in Wisconsin and which may be expected
to occur on a particular stream because of like physical characteristics.
The flood frequency of the regional flood is once in every 100 years;
this means that in any given year, there is a one-percent chance that
the regional flood may occur or be exceeded. During a typical thirty-year
mortgage period, the regional flood has a twenty-six-percent chance
of occurrence.
SANITARY PRIVY
An outhouse or structure used for deposition of human excrement.
SEPTIC TANK
A watertight, covered receptacle which receives crude, untreated
sewage and by bacterial action and sedimentation effects a process
of clarification and decomposition of the solid sewage, discharges
and effluent.
SERVICING
The cleaning, removing, hauling and disposing of scum, liquid,
sludge or other wastes.
