EXTENSION
The extension of any local or regional sewer into territory not already
served by the regional or local system.
FEDERAL ACT
The Federal Water Pollution Control Act (33 U.S.C. § 1251
et seq., as amended from time to time) and the Clean Water Act (33 U.S.C.
§ 1317 et seq., as amended from time to time), as implemented by
Ch. 147, Wis. Stats., and appropriate sections of the Wisconsin Administrative
Code, as well as any applicable guidelines, limitations and standards promulgated
by the United States Environmental Protection Agency pursuant to the federal
act.
FIXED CHARGE
A fixed monthly or quarterly sewer user charge typically based on
the size of the water meter(s) (i.e., equivalent meter) servicing such user.
The fixed charge may recover certain debt costs and fixed operating, maintenance
and repair costs.
FLOATABLE OIL
Oil, fat, or a similar substance in a physical state such that it
will separate by gravity from wastewater by treatment in an approved pretreatment
facility. A wastewater shall be considered free of floatable oil if it is
properly pretreated and does not interfere with the collection or treatment
system.
FLOW or WASTEWATER FLOW
Wastewater which enters the sanitary sewer system tributary to the
wastewater treatment facility and includes volume, BOD, suspended solids,
and such additional parameters as may from time to time be determined by the
DIWC or the Commission Engineer.
FORCE MAIN
A sanitary sewer that transports wastewater under pressure. Because
it is a type of sanitary sewer main, a force main typically transports wastewater
from collector sewers to a point for treatment and disposal. In the DIWC context,
the force mains generally run from the lift stations to the wastewater treatment
plant and are owned by the DIWC. The local sewerage system may also have force
mains that transport wastewater from collector sewers and eventually connect
through the lift station to the DIWC force mains. (The terms "sanitary sewer
main," "main sewer" and "interceptor sewer" are often used interchangeably.)
GARBAGE
The animal and vegetable waste resulting from the handling, preparation,
cooking and serving of foods or from the handling, storage or sale of food
products and produce.
GRAVITY MAIN
A sanitary sewer that transports wastewater by gravity. Because it
is a type of sanitary sewer main, a gravity main typically transports wastewater
from collector sewers to a point for treatment and disposal. In the DIWC context,
the initial design plans do not include any gravity mains from the lift stations
to the wastewater treatment plant and, consequently, the DIWC is unlikely
to own any gravity mains. The local sewerage system relies heavily on gravity
mains to transport wastewater from collector sewers and eventually connects
through the lift station to the DIWC force mains. (The terms "sanitary sewer
main," "main sewer" and "interceptor sewer" are often used interchangeably.)
GREASE TRAP or SAND AND GREASE TRAP
A pretreatment system that is designed to remove sand and floatable
wastes, such as oils and greases, which sand and floatable waste inhibits
the operation and maintenance of the sewage force main, sewer or wastewater
treatment system.
GROUND GARBAGE
The residue from the preparation, cooking, and dispensing of food
that has been shredded to such degree that all particle will be no greater
than 1/2 inch in any dimension and will be carried freely in suspension under
normal flow conditions prevailing in public sewers.
HOLDING TANK WASTE
The scum, liquid, sludge or other waste from holding tanks such as
chemical toilets, campers, trailers, vacuum-pump tank trucks and other temporary
holding facilities that collect wastewater from a user. "Holding tank waste"
does not include sludge, or waste from a soil absorption field, septic tank,
privy or grease trap.
INCOMPATIBLE POLLUTANT
Any pollutant which is not a compatible pollutant. Incompatible pollutants
include any wastewater or discharges to the local or regional system that
are likely to adversely affect or disrupt the wastewater treatment processes
or effluent quality or sludge quality, as determined by applicable federal,
state or local governmental law, or by the Commission Engineer based on generally
accepted industry practices such as those set forth in "Wastewater Treatment
Plant: A Manual of Practice," Standard Methods, and those standards or practices
reasonably established by the Commission.
INDUSTRIAL-STRENGTH WASTEWATER, INDUSTRIAL WASTEWATER or INDUSTRIAL
DISCHARGE
All wastewater other than domestic-strength wastewater. Industrial-strength
wastewater includes waterborne solids, liquids or gaseous wastes resulting
from or discharging from an industrial process, trade or business, or otherwise
escaping into the wastewater facilities. Industrial discharges include, but
are not limited to, cooling water and discharges from wastewater pretreatment
facilities.
INDUSTRIAL USER
Any user who makes, causes, or permits an industrial discharge into
the District's wastewater facilities. Industrial users include any user defined
in 40 CFR 35.905-8, as amended.
INFILTRATION
The water (other than wastewater) from the ground or other sources
that enters the local or regional system through means such as, but not limited
to, defective pipes, pipe joints, connections or manhole walls. Infiltration
does not include, and is distinguishable from, inflow.
INFLOW
The water (other than wastewater) that enters the local and regional
system from, but not limited to, roof leaders, cellar drains, yard drains,
area drains, foundation drains, drains from springs and swampy areas, manhole
covers, cross-connections between storm sewers and sanitary sewers, catch
basins, cooling towers, stormwaters, surface runoff, street wash waters or
drainage. Inflow does not include, and is distinguishable from, infiltration.
INTERFERENCE
The inhibition or disruption of the sewerage system, or wastewater
treatment processes or operations, which may or does contribute to a violation
of any condition of the Commission's WPDES permit.
LICENSED DISPOSER
A person holding a valid license to do septage or holding tank servicing
under Ch. NR 113, Wis. Adm. Code, as may be amended from time to time.
LIMITED CONTRACT USER
A municipality, entity or individual who enters and is bound to the
Commission by a limited purpose contract for limited use of excess treatment
capacity or other limited purposes approved by the Commission. For example,
the Village of Cross Plains is a limited contract user with respect to biosolids
treatment.
LOCAL SEWER(S) or LOCAL SYSTEM or LOCAL SEWERAGE SYSTEM
Wastewater facilities owned by a contracting municipality or the
School District which are, or may be, connected with the regional system.
The local sewer extends from its point of origin (typically the point where
a building sewer connects with another public sewer) to the first contact
with the regional system wet well or the screening area of the lift stations
where the local sewer connects to the regional system.
NATIONAL CATEGORICAL PRETREATMENT STANDARDS
Any regulation or order containing pollutant discharge limitations
as promulgated by the U.S. Environmental Protection Agency in accordance with
Section 307(b) and (c) of the Clean Water Act (33 U.S.C. § 317 et

have not been prescribed because the source commenced after the publication
of proposed regulations prescribing National Categorical Pretreatment Standards
pursuant to Section 307(c) (33 U.S.C. § 1317 et seq., as amended
from time to time). The Commission Engineer shall prescribe appropriate standards
for new sources until such time as the same are prescribed by the National
Categorical Pretreatment Standards.
OPERATION, MAINTENANCE AND REPLACEMENT COSTS or OM&R COSTS

REGIONAL SEWER(S) or REGIONAL SYSTEM or REGIONAL SEWERAGE SYSTEM
All wastewater treatment facilities owned and operated by the Commission,
plus any and all additions, extensions, improvements, renewals and/or replacements
thereto. The regional system begins and extends from its point of origin at
the regional system wet well or the screening area of the lift stations where
the local sewer connects to the regional system and continues through and
includes the regional system meter, the wet well or the screening area of
the lift station, the sanitary force mains, and connections and appurtenances
to and including the wastewater treatment plant. The regional system does
not include the local sewer system of any contracting municipality, the School
District or a limited contract user.

and the School District ("regional sewer service charge") to pay for debt
retirement costs for capital expenditures as well as the operation, maintenance
and replacement costs of the local and regional system. (The basic sewer service
charge does not include surcharges, special charges or connection charges.)
SIGNIFICANT DISCHARGER
Any customer or user who discharges high-strength wastewater that
exceeds the loading or volume of typical domestic wastewater, as determined
on a case-by-case basis by the Commission Engineer in consultation with the
Village. For example, a customer or user who discharges wastewater with a
loading in excess of 300 mg/l of BOD may be considered a significant discharger.
The Commission and Village may develop special surcharges and/or an equivalent
meter system for significant dischargers to equitably apply the basic sewer
user charges and capital cost recovery or standby charges to significant dischargers.
All significant industrial contributors shall be considered significant dischargers.
(Additional criteria for identifying significant dischargers is set forth
in Exhibits E and F of Commission Resolution 99-03, which sets forth the methodology
for regional connection fees and surcharges applicable to significant dischargers
and which is incorporated by reference as if set forth in full herein.)
