For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
BIOCHEMICAL OXYGEN DEMAND (BOD). The quantity of oxygen utilized in the biochemical oxidation of organic 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 (one and one-half meters) 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, also called “house connection” or “hookup”.
CITY. Myton City, Utah.
CITY COUNCIL. The City Council of Myton City.
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.
INDUSTRIAL WASTES. The wastewater from industrial processes, trade or business, as distinct from domestic or sanitary wastes.
MAY. Is permissive. (See definition of SHALL.)
NATURAL OUTLET. Any outlet, including storm sewers and combined sewer overflows, into a watercourse, pond, ditch, lake or other body of surface or ground water.
PERSON. Any individual, firm, company, association, society, corporation or group.
pH. The logarithm of the reciprocal of the hydrogen ions, in grams, per liter of solution. Neutral water, for example, has a pH value of 7 and hydrogen ion concentration of 10-.
PROPERLY SHREDDED GARBAGE. The wastes 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 one-half inch (1.27 centimeters) in any dimension.
PUBLIC SEWER. A common sewer 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, drain and surface waters that are not admitted intentionally.
SEWAGE. The spent water of a community. The preferred term is WASTEWATER, as defined in this section.
SEWER. A pipe or conduit that carries wastewater or drainage water.
SHALL. Is mandatory. (See definition of MAY.)
SLUDGE. 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 of flows during normal operation and shall adversely affect the collection system and/or performance of the wastewater treatment works.
SLUG, WATER SLUG. An amount of water discharged into the sanitary sewer system in a volume in excess of that normally anticipated in normal system operations. SLUGS represent amounts and volumes of water of sufficient mass and velocity that in an undampended or underdampened condition may reasonably be expected to lead to or induce the presence of a water hammer in the system. Such accelerating and trapped water slugs proceeding through a pipeline create the very real prospect of system damage or failure due to hydrodynamic loads (i.e., force time curves) on various pipe segments of the system’s infrastructure.
STORM DRAIN or STORM SEWER. A drain or sewer for conveying water, ground water, subsurface water or unpolluted water from any source.
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 benefitted by discharge to the sanitary sewers and wastewater treatment facilities provided.
UTILITIES MAINTENANCE PERSON. The person employed by Myton City for the overall maintenance of wastewater facilities of Myton City, or his or her authorized deputy, agent or representative.
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, together with any ground water, surface water and storm water that may be present.
WASTEWATER FACILITIES. The structures, equipment and process required to collect, carry away and treat domestic and industrial waste, and dispose of the effluent.
WASTEWATER TREATMENT WORKS. An arrangement of devices and structures for treating wastewater, industrial waste 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.
