of organic matter under standard laboratory procedure in five (5)
days at twenty degrees Celsius (20° C.), expressed in milligrams
per liter.
BUILDING DRAIN
That part of the lowest horizontal piping of a drainage system

control plant."
WATERCOURSE
A natural or artificial channel for the passage of water
