COMMERCIAL USER. Any place of business which discharges sanitary waste as distinct from industrial wastewater.
DEBT SERVICE CHARGE. A charge levied on users of wastewater treatment facilities for the cost of repaying money bonded to construct the facilities.
EXTRA STRENGTH WASTE. Wastewater having a BOD5 and/or TSS greater than domestic waste and not otherwise classified as an incompatible waste.
GOVERNMENTAL USER. Users which are units, agencies or instrumentalities of federal, state or local government discharging normal domestic strength wastewater.
INCOMPATIBLE WASTE. Waste that either singly or by interaction with other wastes interferes with any waste treatment process, constitutes a hazard to humans or animals, creates a public nuisance or creates any hazard in the receiving waters of the wastewater treatment works.
INDUSTRIAL USERS or INDUSTRIES.
(1) (a) Entitles that discharge into a publicly owned wastewater treatment works, liquid wastes resulting from the processes employed in industrial or manufacturing processes, or from the development of any natural resources. These are identified in the Standard Industrial Classification Manual, 1972, Office of Management and Budget, as amended and supplemental under one of the following divisions:

5. Division I - Services.
(b) For the purpose of this definition, domestic waste shall be considered to have the following characteristics:
BOD
5 | Less than 222 mg/l |
Suspended solids | Less than 260 mg/l |
(2) 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 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 treatment works.
INDUSTRIAL WASTEWATER. The liquid processing wastes from an industrial manufacturing process, trade or business including but not limited to all Standard Industrial Classification Manual Divisions A, B, D, E and I manufacturers as distinct from domestic wastewater.
INSTITUTIONAL USER. Users other than commercial, governmental, industrial or residential users, discharging primarily normal domestic strength wastewater (such as, non-profit organizations).
NORMAL DOMESTIC STRENGTH WASTEWATER. Wastewater that is primarily produced by residential users with BOD5 concentrations not greater than 222 mg/l and suspended solids concentrations not greater than 260 mg/l.
OPERATION AND MAINTENANCE. Activities required to provide for the dependable and economical functioning of the treatment works, throughout the design or useful life, whichever is longer of the treatment works, and at the level of performance for which the treatment works were constructed. OPERATION AND MAINTENANCE includes replacement.
OPERATION AND MAINTENANCE COSTS. Expenditures for operation and maintenance, including replacement.
PUBLIC WASTEWATER COLLECTION SYSTEM. A system of sanitary sewers owned, maintained, operated and controlled by the city.
REPLACEMENT. Obtaining and installing of equipment, accessories or appurtenances which are necessary during the design life or useful life, whichever is longer, of the treatment works to maintain the capacity and performance for which the works were designed and constructed.
REPLACEMENT COSTS. Expenditures for replacement.
RESIDENTIAL USER. A user of the treatment facilities whose premises or building is used primarily as a residence for one or more persons, including dwelling units such as detached and semi-detached housing, apartments and mobile homes; and which discharges primarily normal domestic strength sanitary wastes.
SANITARY SEWER. A sewer intended to carry only liquid and water carried wastes from residences, commercial buildings, industrial plants and institutions, together with minor quantities of ground, storm and surface waters which are not admitted intentionally.
SEWER SERVICE CHARGE. The aggregate of all charges, including charges for operation, maintenance, replacement, debt service and other sewer related charges that are billed periodically to users to the city’s wastewater treatment facilities.

Expenditure of the SEWER SERVICE FUND will be for operation, maintenance and replacement costs and to retire debt incurred through capital expenditure for wastewater treatment.
SLUG. 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 or flows during normal operation and shall adversely affect the collection system and/or performance of the wastewater treatment works.
STANDARD INDUSTRIAL CLASSIFICATION MANUAL. Office of Management and Budget, 1972.
SUSPENDED SOLIDS (SS) or TOTAL SUSPENDED SOLIDS (TSS). The total suspended matter that either floats on the surface or is in suspension in water, wastewater or other liquids, and is removable by laboratory filtering as prescribed in Standard Methods for the Examination of Water and Wastewater, latest edition, and referred to as non-filterable residue.
TOXIC POLLUTANT. The concentration of any pollutant or combination of pollutants as defined in standards issued pursuant to § 307(a) of the Act, which upon exposure to or assimilation into any organism will cause adverse effects.
