Definitions. Unless the context specifically indicates
otherwise, the meaning of terms used in this chapter shall be as follows:
ASTM

BIOCHEMICAL OXYGEN DEMAND (BOD)
The quantity of oxygen utilized in the biochemical oxidation
of matter under standard laboratory procedure in five days at 20º
C., expressed in milligrams per liter.
BUILDING DRAIN

surface water.
EASEMENT
An acquired legal right for the specific use of land owned
by others.
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. A wastewater shall be considered free of floatable fat if
it is properly pretreated and the wastewater does not interfere with
the collection system.

in effect or water that would not cause violation of receiving water
quality standards and would not be benefited by discharge to the sanitary
