For the purpose of this chapter the following definitions shall apply unless the context clearly indicates or requires a different meaning.
B.O.D. (denoting "BIOCHEMICAL OXYGEN DEMAND"). That quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure in five days at 20°C., expressed in parts per million by weight. B.O.D. shall be determined as described under the heading "Biochemical Oxygen Demand" in the latest edition of "Standard Methods for the Examination of Water, Sewage, and Industrial Wastes", as published jointly by the American Public Health Association, and the Federation of Sewage and Industrial Wastes Associations.
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 outside the inner face of the building wall.
BUILDING SEWER. The extension from the building drain to the public sewer or other place of disposal.
COMBINED SEWER. A sewer receiving both surface runoff and sewage.
GARBAGE. Solid wastes from the preparation, cooking, and dispensing of food, and from the handling, storage, and sale of produce.
INDUSTRIAL WASTES. The liquid wastes from industrial, commercial, or manufacturing processes, as distinct from sanitary sewage.
LANDSCAPE METER. A water meter installed on a new irrigation service line that shall only be connected to a closed lawn irrigation system.
NATURAL OUTLET. Any outlet into a watercourse, pond, ditch, lake, or other body of surface or ground water.
pH. The logarithm of the reciprocal of the weight of hydrogen ions in grams per liter of solution.
PROPERLY SHREDDED GARBAGE. Waste from the preparation, cooking, and dispensing of food that has 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 1/2-inch in any dimension.
PUBLIC SEWER. A sewer in which all owners of abutting properties have equal rights, and which is controlled by public authority.
SANITARY SEWAGE. The waste from water closets, urinals, lavatories, sinks, bathtubs, showers, household laundries, cellar floor drains, garage floor drains, bars, soda fountains, cuspidors, refrigerator drips, drinking fountains, and stable floor drains.
SANITARY SEWER. A sewer which carries sewage and to which storm, surface, and ground waters are not intentionally admitted.
SEWAGE. A combination of the water-carried wastes from residences, business buildings, institutions, and industrial establishments, together with such ground, surface, and storm waters as may be present.
SEWAGE TREATMENT PLANT. Any arrangement of devices and structures used for treating sewage.
SEWAGE WORKS. All facilities for collecting, pumping, treating, and disposing of sewage.
SEWER. A pipe or conduit for carrying sewage.
STORM SEWER or STORM DRAIN. A sewer which carries storm and surface waters and drainage, but excludes sewage and polluted industrial wastes.
SUPERINTENDENT. The Wastewater Treatment Superintendent when reference is made to the sanitary sewer system, and the Public Works Superintendent when reference is made to the storm sewer system.
SUSPENDED SOLIDS. The dry weight of the solids physically suspended in a flow of sewage, industrial waste, or water is determined by the method of determining suspended matter described under the heading "Suspended Matter" in the latest edition of "Standard Methods for the Examination of Water, Sewage, and Industrial Wastes", as published jointly by the American Public Health Association, the American Water Works Association, and the Federation of Sewage and Industrial Wastes Associations, and expressed in parts per million by weight.
WATERCOURSE. A channel in which a flow of water occurs, either continuously or intermittently.
