A. 
Unless the context specifically indicates otherwise, the meanings of terms used in this chapter shall be as follows:
ASTM
American Society for Testing and Materials.
BIOCHEMICAL OXYGEN DEMAND (BOD)
The quantity of oxygen utilized in the biochemical oxidation of matter under standard laboratory procedure in five days at 20° C., expressed in milligrams per liter.
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.
BUILDING SEWER (ALSO CALLED "HOUSE CONNECTION")
The extension from the building drain to the public sewer or other place of disposal.
COMBINED SEWER
A sewer intended to receive both wastewater and storm- or 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.
GARBAGE
The animal and vegetable waste resulting from the handling, preparation, cooking and serving of foods and from the sale and storage of produce.
INDUSTRIAL WASTES
The wastewater from industrial processes, trade or business, as distinct from domestic or sanitary wastes.
NATURAL OUTLET

OPERATOR
The operator of the wastewater facilities of the Incorporated Village of Ocean Beach, or his authorized deputy, agent or representative.
PERSON
Any individual, firm, company, association, society, corporation or group.
pH
The reciprocal of the logarithm 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 seven and a hydrogen-ion concentration of 10-7 grams per liter.
PUBLIC SEWER
A common sewer controlled by a governmental agency or public utility.
SANITARY SEWER
A sewer that carried 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.
SEWAGE
The spent water of a community. The preferred term is "wastewater."
SEWER
A pipe or conduit that carries wastewater or drainage water.
SHREDDED GARBAGE
The wastes from the preparation, cooking and dispensing of food that have been shredded to such a degree that particles will be carried freely under the flow conditions normally prevailing in public sewers.
SLUG
Any discharge of water, wastewater or industrial wastewater, which in concentration of any given constituent or in quantity of flow, exceeds, for any period of duration longer than 15 minutes, five times the average twenty-four-hour concentration or flow during normal operation and which may adversely affect the collection system and/or performance of the wastewater treatment works.
STORM DRAIN (SOMETIMES TERMED "STORM SEWER")
A drain or sewer for conveying water, groundwater, subsurface water or unpolluted water from any source. All wastewaters shall be considered to be polluted.
SUSPENDED SOLIDS
Total suspended matter that either floats on the surface of, 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
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 benefited by discharge to the sanitary sewers and wastewater treatment facilities provided.
VILLAGE SUPERINTENDENT
The individual employed by the Incorporated Village of Ocean Beach who is responsible for the overall operation and maintenance of the wastewater, water and solid waste facilities and for the maintenance of village properties. The term "Superintendent," as used in this chapter, shall have the same meaning as "Village Superintendent."

WASTEWATER FACILITIES
The structures, equipment and processes required to collect, transmit and treat domestic and industrial wastes and dispose of the treated 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.
