Definitions. Unless the context specifically indicates otherwise, the meaning of terms in this Part
1 of this chapter shall be as follows:
BOD (denoting "biochemical oxygen demand")
The quantity of oxygen utilized in the biochemical oxidation
of organic matter under standard laboratory procedure for five days
at 20º C., expressed in parts per million by weight.
BUILDING DRAIN
That part of the lowest horizontal piping of the drainage
system which receives the discharge from soil, waste and other drainage
pipe inside the walls of the building and conveys it to the building
sewer beginning five feet outside the inner face of the building wall.
BUILDING SEWER
The extension from the building drain to the public sewer
or to an existing extension from a public sewer when available.
COOLING WATER
The water discharged from any system of condensation, air
conditioning, cooling, refrigeration or other system, but which shall
be free from odor and oil. It shall contain no polluting substances
which would produce either BOD or suspended solids in excess of 10
parts per million by weight.
ENGINEER
The Engineer of the Town of LaGrange or his authorized deputy,
agent or representative.
GARBAGE
Solid wastes from the preparation, cooking and dispensing
of food and from the handling, storage and sale of produce.
INDUSTRIAL WASTES

sanitary sewage.
NATURAL OUTLET
Any outlet into a watercourse, pond, ditch, lake or other
body of surface or ground water.
NORMAL SEWAGE
Sewage shall be regarded as normal for the Town if analyses
show, by weight, a daily average of not more than 300 parts per million
of suspended solids, not more than 240 parts per million of BOD and
not more than 50 parts per million of either grease or oil (soluble
matter) each per million gallons of daily flow.
pH
The logarithm of the reciprocal of the weight of hydrogen
ions in grams per liter of solution. It is used to indicate the concentration
of free acid and free alkali.
PROPERLY SHREDDED GARBAGE
Garbage that has been shredded to such 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 in any dimension.
PUBLIC SEWER
A sewer in which all owners of abutting properties have equal
rights and which is controlled by public authority.
SANITARY SEWAGE
Sewage discharging from the sanitary conveniences of dwellings
(including apartment houses and hotels), office buildings, factories
or institutions and free from storm and surface waters and industrial
wastes.
SEWAGE
A combination of water-carried wastes from residences, buildings,
institutions and industrial establishments, together with such ground-
, surface and storm waters as may be present.
SEWER
A pipe or conduit for carrying sewage and to which storm-
, surface and ground waters are not intentionally admitted.
SLUG
Any water or waste exceeding a concentration greater than
five times the normal sewage and which is discharged continually for
a period longer than 15 minutes.
STORM SEWER or STORM DRAIN
A pipe or conduit which carries storm- and surface water
and drainage, but excludes sewage and industrial wastes. It may, however,
carry cooling water or other unpolluted waters.
SUBDIVISION
The division of any parcel of land into two or more lots,
plots, sites or other division of land, with or without streets, for
the purpose of immediate or future sale or building development, except
that the division of land for agricultural purposes into parcels of

shall be exempted from the application of this term.

Any water or waste containing none of the following: free
or emulsified grease or oil; acid or alkali; phenols or other substances
imparting taste or odor in receiving waters; toxic or poisonous substances
in suspension, colloidal state or solution; and noxious or odorous
gases. It shall contain not more than 10,000 parts per million by
weight of dissolved solids, of which not more than 2,500 parts per
million shall be as chloride with permissible volumes subject to review
by the Engineer, and not more than 10 parts per million each of suspended
solids and BOD. The color shall not exceed 50 parts per million.
WATERCOURSE
A channel in which a flow of water occurs, either continuously
or intermittently.
