BOARD OF WORKS. The Town Council or its authorized deputy, agent, or representative.
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.

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.
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 sanitary wastes.
MAY. Is permissive.
NATURAL OUTLET. Any outlet, including storm sewers, into a watercourse, pond, ditch, lake or other body of surface or groundwater.

NPDES PERMIT. A permit obtained from the State of Indiana by the Sewage Works to discharge treated wastewaters of the Sewage Works into a watercourse.
PERSON. Any individual, firm, company, association, society, corporation, or group.
pH. The logarithm of the reciprocal of the hydrogen-ion 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 ½ inch (1.27 centimeters) in any dimension.
PUBLIC SEWER. A sewer or other wastewater facility 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.

SEWER. A pipe or conduit that carries wastewater.
SHALL. Is mandatory.
SLUDGE.

STORM DRAIN. A drain for conveying water, groundwater, subsurface water, or unpolluted water from any source.
SUPERINTENDENT. The Superintendent of the Wastewater Treatment Works of the town, the certified operator, or the authorized deputy, agent, or representative of either.

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.
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.
