— 28, 5-11-1982]
Unless the context specifically indicates otherwise, the meaning
of terms used in this chapter shall be as follows:
BIOCHEMICAL OXYGEN DEMAND (BOD)
The quantity of oxygen utilized in the biochemical oxidation
of organic matter under standard laboratory procedure in five days
at 20° C., expressed in milligrams per liter.
BUILDING DRAIN
That part of the lowest horizontal piping of a drainage system
which receives the discharge from soil, waste and other drainage pipes
inside the walls of the building and conveys it to the building sewer,
beginning five feet (1.5 meters) outside the inner face of the building
wall.
BUILDING SEWER
The extension from the building drain to the public sewer
or other place of disposal, also called house connection.
COMBINED SEWER
A sewer intended to receive both wastewater and storm or
surface water.
EASEMENT
An acquired legal right for the specific use of land owned
by others.
FLOATABLE OIL
Is oil, fat, or grease 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 fat if
it is properly pretreated and the wastewater does not interfere with
the collection system.
GARBAGE
The animal and vegetable waste resulting from the handling,
preparation, cooking and serving of foods.
INDUSTRIAL WASTES
The wastewater from industrial processes, trade, or business
as distinct from domestic or sanitary wastes.
MAY
Is permissive (see "shall," below).
NATURAL OUTLET
Any outlet, including storm sewers and combined sewer overflows,
into a watercourse, pond, ditch, lake, or other body of surface or
groundwater.
PERSON
Any individual, firm, company, association, society, corporation
or group.
PH
The logarithm of the reciprocal of the hydrogenion concentration.
The concentration is the weight of hydrogen ions, in grams, per liter
of solution. Neutral water, for example, has a pH value of 7 and a
hydrogen-ion concentration of 10-7.
PROPERLY SHREDDED GARBAGE
The wastes from the preparation, cooking and 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
public sewers, with no particle greater than 1/2 inch (1.27 centimeters)
in any dimension.
PUBLIC SEWER
A common sewer controlled by a governmental agency or public
utility.
SANITARY SEWER
A sewer that carries liquid and water-carried wastes from
residences, commercial buildings, industrial plants and institutions,
together with minor quantities of ground, storm, and surface waters
that are not admitted intentionally.
SEWAGE
Is the spent water of a community. The preferred term is
"wastewater," as defined below.
SEWER
A pipe or conduit that carries wastewater or drainage water.
SHALL
Is mandatory (see "may," above).
SLUG
Any discharge of water or wastewater which in concentration
of any given constituent or in quantity of flow exceeds for any period
of duration longer than 15 minutes more than five times the average
twenty-four-hour concentration or flows during normal operation and
shall adversely affect the collection system and/or performance of
the wastewater treatment works.
STORM DRAIN OR STORM SEWER
A drain or sewer for conveying water, groundwater, subsurface
water, or unpolluted water from every source.
SUPERINTENDENT
The superintendent of wastewater facilities and/or of wastewater
treatment works and/or of water pollution control of the city or his
authorized deputy, agent or representative.
SUSPENDED SOLIDS
Total suspended matter that either floats on the surface
of, or is in suspension in water, wastewater, or other liquids, and
that is removable by laboratory filtering as prescribed in "Standard
Methods for the Examination of Water and Wastewater" and referred
to as nonfilterable residue.
UNPOLLUTED WATER
Is water of quality equal to or better than the effluent
criteria in effect or water that would not cause violation of receiving
water quality standards and would not be benefited by discharge to
the sanitary sewers and wastewater treatment facilities provided.
WASTEWATER
The spent water of a community. From the standpoint of source,
it may be a combination of the liquid and water-carried wastes from
residences, commercial buildings, industrial plants and institutions,
together with any groundwater, surface water, and stormwater that
may be present.
WASTEWATER FACILITIES
The structures, equipment, and processes required to collect,
carry away and treat domestic and industrial wastes and dispose of
the effluent.
WASTEWATER TREATMENT WORKS
An arrangement of devices and structures for treating wastewater,
industrial wastes and sludge. Sometimes used as synonymous with "waste
treatment plant" or "wastewater treatment plant" or "water pollution
control plant."
WATERCOURSE
A natural or artificial channel for the passage of water
either continuously or intermittently.
