For the purpose of this chapter the following definitions shall apply unless the context clearly indicates or requires a different meaning.
BOD. (Biochemical Oxygen Demand) 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 SEWER. The extension from the building to the public sewer of the village including that part of the lowest 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 public sewer beginning five feet (1.5 meters) outside the inner face of the building wall.
CONTROL MANHOLE. A structure located on a site from which industrial wastes are discharged. Where feasible, the manhole shall have an interior drop.
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. Wastewater shall be considered free of floatable fat if it is properly pretreated and the wastewater does not interfere with the collection system.
GARBAGE. Solid wastes from the domestic and commercial preparation, cooking, and dispensing of food, and from the handling, storage, and sale of produce.
INDUSTRIAL USER. Any user of publicly owned treatment works:
(1) Identified in the Standard Industrial Classification Manual, 1972, Office of Management and Budget, as amended and supplemented, under the following divisions:
(a) Division A: Agriculture, Forestry, and Fishing.
(b) Division B: Mining.
(c) Division D: Manufacturing.
(d) Division E: Transportation, Communications, Electric, Gas and Sanitary Services.
(e) Division I: Services.
(2) A user in the divisions listed may be excluded if it is determined by the village or the Springfield Sanitary District that it will introduce primarily segregated domestic waste or wastes from sanitary conveniences; or discharge wastewater to the public sewer which contains toxic pollutants or poisonous solids, liquids, or gases in sufficient quantity either singly or by interaction with other wastes, to contaminate the sludge of the wastewater treatment plant, or to injure or interfere with any sewage treatment process, or which constitutes a hazard to humans or animals, creates a public nuisance, or creates any hazard in or has an adverse effect on the waters receiving any discharge from the wastewater treatment works.
INDUSTRIAL WASTE. Any solid, liquid, or gaseous substance discharged, permitted to flow, or escaping from any industrial, manufacturing, commercial, or business establishment, or process or from the development, recovery, or processing of any natural resource as distinct from sanitary sewage.
MAJOR CONTRIBUTING INDUSTRY. An industrial user of the publicly owned treatment works that has a flow of 25,000 gallons or more per average work day; has a flow greater than 10% of the flow carried by the municipal system receiving the waste; has in its waste, a toxic pollutant in toxic amounts as defined in standards issued under § 307(a) of the Federal Act; or is found by the permit issuance authority, in connection with the issuance of the NPDES permit to the publicly owned treatment works receiving the waste, to have significant impact, either singly or in combination with other contributing industries, on that treatment works or upon the quality of effluent from that treatment works.
MILLIGRAMS PER LITER. A unit of the concentration of water or wastewater constituent, being 0.001 g of the constituent in 1,000 ml of water.
NATURAL OUTLET. Any outlet into a watercourse, pond, ditch, lake, or other body of surface or groundwater.
pH. The logarithm (base 10) of the reciprocal of the hydrogen-ion concentration expressed by procedures outlined in Standard Methods.
ppm. Parts per million by weight.
PRETREATMENT. The treatment of wastewaters from sources before introduction into the sanitary sewer system of the village.
PROPERLY SHREDDED GARBAGE. 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 one-half inch (1.27 centimeters) in any dimension.
PUBLIC SEWER. The sanitary sewer of the village. It shall include sewers within or outside the village boundaries that serve one or more persons and ultimately discharge into the village sanitary sewer system, even though such sewers may not have been constructed with village funds.
RESIDENTIAL OR COMMERCIAL USER or NON-INDUSTRIAL. Any user of the public sewer of the village not classified as an industrial user or excluded as an industrial user as provided for in this section.
SANITARY SEWER. A sewer that conveys sewage or industrial wastes or a combination of both, and into which storm, surface, and groundwaters or unpolluted industrial wastes are not intentionally admitted.
SEWER. A pipe or conduit for conveying sewage or any other waste liquids, including storm, surface, and groundwater drainage.
SEWERAGE. The system of sewers and appurtenances for the collection, transportation, and pumping of sewage.
SLUG. Any discharge of water, sewage, or industrial waste 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 or flows during normal operation.
STANDARD METHODS. The examination and analytical procedures set forth in the most recent edition of Standard Methods for the Examination of Water and Wastewater published jointly by the American Public Health Association, the American Water Works Association and the Water Pollution Control Federation.
STORM SEWER. A sewer that carries storm, surface, and groundwater drainage but excludes sewage and industrial wastes other than unpolluted cooling water.
STORM WATER RUNOFF. That portion of precipitation that is drained into the sewers.
SUSPENDED SOLIDS. Solids that either float on the surface of, or are in suspension in water, sewage, or industrial waste, and which are removable by a laboratory filtration device. Quantitative determination of SUSPENDED SOLIDS shall be made in accordance with procedures set forth in Standard Methods.
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.
USER CLASS. The type of user either "residential or commercial" (non industrial) or "industrial" as defined herein.
WASTEWATER or SEWAGE. The spent water of a community, which may be a combination of the liquid and water-carried wastes from residences, commercial buildings, industrial plants, and institutions, together with any groundwater, surface water, and stormwater that may be present.
WASTEWATER FACILITIES. The structures, equipment, and processes required to collect, carry away, and treat domestic and industrial wastes and transport effluent to a watercourse.
WATERCOURSE. A channel in which a flow of water occurs, either continuously or intermittently.
