(Ord. 622 Art. 1 § 3, 1981)
"Garbage"
means solid wastes from the domestic and commercial preparation, cooking and dispensing of food, and from the handling, storage and sale of produce.
(Ord. 622 Art. 1 § 7, 1981)
"Industrial user"
means as follows:
A. 
Any nongovernmental, nonresidential user of a publicly owned treatment works which discharges more than the equivalent of twenty-five thousand gallons per day (gpd) of sanitary wastes and which is identified in the Standard Industrial Classification Manual, 1972, Office of Management and Budget, as amended and supplemented, under one of the following divisions:
Division A. Agriculture, Forestry and Fishing
Division B. Mining
Division D. Manufacturing
Division E. Transportation, Communications, Electric, Gas and Sanitary Services
Division I. Services
1.
In determining the amount of a user's discharge for purposes of ICR, domestic wastes or discharges from sanitary conveniences may be excluded.
2.
After applying the sanitary waste exclusion, dischargers in the above divisions that have a volume exceeding twenty-five thousand gpd or the weight of BOD or SS equivalent to that found in twenty-five thousand gpd of sanitary waste are considered industrial users. Sanitary wastes, for purposes of this calculation of equivalency, are wastes discharged from average residential user in the service area without regard to considering the effect of dilution caused by infiltration and/or inflow. The strength of the average residential waste discharged within the service area has been determined to be two hundred sixty milligrams per liter of BOD and two hundred fifty milligrams per liter of SS;
B. 
Any nongovernmental user of a publicly owned treatment works which discharges wastewater to the treatment works 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 any municipal systems or to injure or to interfere with any wastewater 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 treatment works; and/or
C. 
All commercial users of an individual system constructed with grant assistance under Section 201(h) of the Clean Water Act of 1977.
(Ord. 622 Art. 1 § 12, 1981)
"Normal domestic waste"
means normal wastewater for the city in which the average concentration of five-day BOD is established at two hundred sixty milligrams per liter and the average concentration of suspended solids is established at two hundred fifty milligrams per liter.
(Ord. 622 Art. 1 § 15, 1981)
"pH"
means the logarithm of the reciprocal of the weight of hydrogen ions in grams per liter of solution.
(Ord. 622 Art. 1 § 17, 1981)
"Properly shredded garbage"
means the wastes from the preparation, cooking, and dispensing of food which 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.
(Ord. 622 Art. 1 § 18, 1981)
"Replacement"
means expenditures for obtaining and installing equipment, accessories, or appurtenances which are necessary to maintain the capacity and performance during the service life of the treatment works for which such works were designed and constructed.
(Ord. 622 Art. 1 § 20, 1981)
"Slug"
means any discharge of water, wastewater or industrial waste which, in concentration of any given constituent or quantity of flow, for any period of duration longer than fifteen minutes, exceeds more than five times the average twenty-four hour concentration or flow quantities during normal operation.
(Ord. 622 Art. 1 § 24, 1981)
"Useful life"
means the estimated period during which a sewage treatment plant will be operated; for the city the design life of twenty years shall be used.
(Ord. 622 Art. 1 § 30, 1981)
"Wastewater"
means a combination of the water-carried wastes from residences, business buildings, institutions and industrial establishments, together with such ground, surface and stormwaters that may be present.
(Ord. 622 Art. 1 § 31, 1981)
"Wastewater collection system"
means each and all of the common lateral sewers within a publicly owned treatment system which are primarily installed to receive wastewaters directly from facilities, which convey wastewater from individual structures or from private property, and which include service connection "Y" fittings designed for connection with those facilities. The facilities which convey wastewater from individual structures or from private property to the public lateral sewer or its equivalent, are specifically excluded from the definition, with the exception of pumping units and pressurized lines for individual structures or groups of structures when such units are cost effective and are owned and maintained by the city.
(Ord. 622 Art. 1 § 32, 1981)
"Wastewater treatment facility"
means any devices and systems used in the storage, treatment, recycling and reclamation of municipal wastewater or industrial wastes of a liquid nature to implement Section 201 of the Federal Water Pollution Control Act (33 U.S.C. 1251 et seq.) as amended by the Federal Water Pollution Control Act Amendments of 1972 (Pub. L. 92-500) and Pub. L. 93-243, or necessary to recycle or reuse water at the most economical cost over the useful life of the works, including intercepting sewers, outfall sewers, wastewater collection systems, pumping, power, and other equipment and their appurtenances; extensions, improvement, remodeling, additions and alternations thereof; elements essential to provide a reliable recycled supply such as standby treatment units and clear well facilities; and any works, including site acquisition of the land that will be an integral part of the treatment process or is used for ultimate disposal or residues resulting from such treatment; or any other method or system for preventing, abating, reducing, storing, treating, separating, or disposing of municipal waste, including storm runoff, or industrial waste, including waste in combined stormwater and sanitary sewer system.
