BOD (Biochemical Oxygen Demand) means the quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure in five days at 20 degrees Centigrade, expressed in milligrams per liter.

Building drain means 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 a building and conveys it to the building sewer, beginning five feet outside the inner face of the building wall.

Building sewer means the extension from the building drain to the public sewer or other place of disposal, also referred to as house connection.

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 means the animal and vegetable waste resulting from the handling, preparation, cooking and serving of foods.

Industrial user is any nongovernmental, nonresidential user of a publicly owned treatment works which discharges more than the equivalent of 25,000 gallons per day (gpd) of sanitary wastes and which is identified in the office of management and budget standard industrial classification manual, as amended and supplemented, under one of the following divisions:

Inflow does not include and is distinguished from infiltration.

pH means the logarithm of the reciprocal of the hydrogen ion concentration. The concentration is the weight of hydrogen ions, in grams, per liter of solution.

Sewer means a pipe or conduit that carries wastewater or drainage water.

Slug means 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 24 hour concentration and/or more than five times the average 24 hour flow, that adversely affects the collection system and/or performance of the wastewater treatment works.

Storm drain (sometimes termed "storm sewer") means a drain or sewer for conveying water, groundwater, subsurface water or unpolluted water from any source.

Suspended solids means total suspended matter that either floats on the surface 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 benefitted by discharge to the sanitary sewers and wastewater treatment facilities provided.

Wastewater department means the municipal department engaged in the business of operating the wastewater system for the town.

Wastewater facilities means the structures, equipment and processes required to collect, carry away and treat domestic and industrial wastes and dispose of the effluent.

Wastewater treatment works means an arrangement of devices and structures for treating wastewater, industrial wastes and sludge. The terms "waste treatment plant," "wastewater treatment plant" and "water pollution control plant" are sometimes used as synonyms.
