greater than 200 mg/l, phosphorus no greater than 10 mg/l and nitrogen
no greater than 33 mg/l.
CATEGORY B
Those sanitary sewer users who discharge greater than 10,000
gallons per day of wastewater or wastewater with concentrations in
excess of 200 mg/l of BOD, 200 mg/l of suspended solids, 10 mg/l of

COSTS, OPERATION AND MAINTENANCE
All costs associated with the operation and maintenance of
the wastewater collection and treatment facilities, as well as the
costs associated with periodic equipment replacement necessary for
maintaining capacity and performance of wastewater collection and
treatment facilities.
COSTS, REPLACEMENT
Expenditures for obtaining and installing equipment, accessories
or appurtenances which are necessary during the useful life of the

for which such facilities were designed and constructed. Operation
and maintenance costs include replacement costs.
DRAINAGE FIXTURE UNIT
Reference the Wisconsin Administrative Code Chapter SPS 382
for related definition.
EASEMENT

by others.
EQUIVALENT HOUSE UNIT (EHU)
The discharge of normal domestic strength wastewater equivalent
in volume to the wastewater discharged by an average family living
unit. (For example, a building containing four apartments would have
four EHUs.) The equivalent housing unit is based on an average of
28 drainage fixture units (DFU) based on § SPS 382.30, Table
382.30-1, Wis. Adm. Code, as summarized below:

FLOATABLE OIL
Oil, fat or grease in a physical state such that it will
separate by gravity from wastewater by treatment in an approved pretreatment
facility. Wastewater shall be considered free of floatable oil if
it is properly pretreated and the wastewater does not interfere with
the collection system.
GARBAGE
Solid waste from the domestic and commercial preparation,
cooking and dispensing of food and from the handling, storage and
sale of produce.
GARBAGE, GROUND
The residue from the preparation, cooking and dispensing
of food that has been shredded to such a degree that all particles
will be carried freely in suspension under the flow conditions normally
prevailing in the public sewers, with no particle greater than 1/2
inch in any dimension.
GARBAGE, PROPERLY SHREDDED
The wastes from the preparation, cooking or dispensing of
food that have been shredded to such a degree that all particles will
be carried freely under the flow conditions normally prevailing in
the public sewers, with no particle greater than 1/2 inch in any dimension.
GRANTEE
The Village of Howards Grove.
IMPACT CHARGE
A charge levied on users of the wastewater collection and
treatment facilities for use of the facilities.
INDUSTRIAL WASTE
The liquid wastes from industrial manufacturing processes,
trade or business as distinct from sanitary sewage.
MAJOR CONTRIBUTING INDUSTRY
An industry that:
A.
Has a flow of 50,000 gallons or more per average workday;
B.
Has a flow greater than 5% of the flow carried by the wastewater
collection and treatment facilities receiving the waste;
C.
Has a material in its discharge included on a list of toxic
pollutants issued under § 283.01(17), Wis. Stats.; or
D.
Has a significant impact, either singularly or in combination
with other contributing industries, on the wastewater treatment facility
or the quality of its effluent.
NATURAL OUTLET
Any outlet, including storm sewers and combined sewer overflows,
into a watercourse, pond, ditch, lake or other body of surface water
or groundwater.
NITROGEN
Kjeldahl nitrogen which is the sum of organic nitrogen and
ammonia nitrogen.
PARTS PER MILLION
A weight-to-weight ratio; the parts per million value multiplied
by the factor 8.34 shall be equivalent to pounds per million gallons
of water.
PERSON
Any and all persons, including any individual, firm, company,
municipal or private corporation, association, society, institution,
enterprise, governmental agency or other entity.

of solution. Neutral water, for example, has a pH value of 7 and a
hydrogen-ion concentration of 10-7.
