CITY
The City of Reedsburg, Wisconsin.
CLEAR (UNPOLLUTED) WATER

a minimum concentration considered harmful by the Wisconsin Department
of Natural Resources, and would not be benefited by discharge to the
wastewater treatment facilities provided. Sources of clear water include
inflow and infiltration.
COMPATIBLE POLLUTANTS
BOD, suspended solids, ammonia, and phosphorus, plus additional
pollutants identified in the Wisconsin Pollutant Discharge Elimination
System (WPDES) permit issued to the City's wastewater treatment plant,
provided that such wastewater treatment plant was designed to treat
such pollutants and does remove such pollutants to a substantial degree.

City's wastewater facilities, including general obligation bonds,
revenue bonds, promissory notes and special assessment bonds with
both principal and interest.
FLOATABLE OIL

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 the wastewater

that have a volume exceeding 1,000 gpd, or the weight of biochemical
oxygen demand (BOD), suspended solids (SS), ammonia (NH3), or phosphorus (P) exceeding the weight found in 1,000
gpd of normal concentration wastewater are considered industrial users.

that contains toxic or incompatible pollutants or poisonous solids,
liquids, or gases in sufficient quantity either singly or by interaction
with other waste, to contaminate the sludge of the municipal sewer
systems, or to injure or to interfere with any sewage treatment process,
or which constitutes a hazard to animals, creates a public nuisance,

grease interceptors, seepage beds, seepage pits, seepage trenches
and privies.
SEPTIC TANK

SEWAGE COLLECTION SYSTEM
The common sanitary sewers within the sewerage system that
are primarily installed to receive wastewaters directly from facilities
which convey wastewater from individual structures or from private

connection with those facilities. The sewage collection system collects
and carries the wastewater through a system that eventually connects
to a wastewater treatment plant. The facilities that convey wastewater
from individual structures, or from private property to the public
sewer, are specifically excluded from the definition of sewage collection
system, except that pumping units and pressurized lines for individual
structures or groups of structures may be included as part of the
sewage collection system when such units are owned and maintained
by the sewerage system owner.
