Sewer: A pipe or conduit for conveying sewage or any other waste liquids, including storm, surface and ground water drainage.

Storm Water Runoff: That portion of the precipitation that is drained into the sewers.
STATE GOVERNMENT:
Director: The director of the Illinois environmental protection agency.
State Act: The Illinois anti-pollution bond act of 1970.
State Grant: The state of Illinois participation in the financing of the construction of treatment works as provided for by the Illinois anti-pollution bond act and for making such grants as filed with the secretary of state of the state of Illinois.
TREATMENT:
Pretreatment: The treatment of wastewaters from sources before introduction into the wastewater treatment works.
Wastewater Treatment Works: An arrangement of devices and structures for treating wastewater, industrial wastes, and sludge. Sometimes used as synonymous with "waste treatment plant" or "wastewater treatment plant" or "pollution control plant".
TYPES OF CHARGES:
Basic User Charge: The basic assessment levied on all users of the public sewer system.
Capital Improvement Charge: A charge levied on users to improve, extend or reconstruct the sewage treatment works.
Local Capital Cost Charge: Charges for costs other than the operation, maintenance and replacement costs, i.e., debt service and capital improvement costs.
Replacement: Expenditures for obtaining and installing equipment, accessories, or appurtenances which are necessary during the useful life of the treatment works to maintain the capacity and performance for which such works were designed and constructed. The term "operation and maintenance" includes "replacement".
Surcharge: The assessment in addition to the basic user charge and debt service charge which is levied on those persons whose wastes are greater in strength than the concentration values.
Useful Life: The estimated period during which the collection system and/or treatment works will be operated.
User Charge: A charge levied on users of treatment works for the cost of operation, maintenance and replacement.
USER TYPES:
Commercial User: Shall include transit lodging, retail and wholesale establishments or places engaged in selling merchandise, or rendering services.
Control Manhole: A structure located on a site from which industrial wastes are discharged. Where feasible, the manhole shall have an interior drop. The purpose of a "control manhole" is to provide access for the city representative to sample and/or measure discharges.
Industrial Users: Shall include establishments engaged in manufacturing activities involving the mechanical or chemical transformation of materials of substance into products.
Institutional/Governmental User: Shall include schools, churches, penal institutions, and users associated with federal, state, and local governments.
Residential User: Any dwelling units such as houses, mobile homes, apartments, and permanent multi-family dwellings.
User Class: The type of user: "residential", "institutional/governmental", "commercial", or "industrial" as defined herein.
WASTEWATER AND ITS CHARACTERISTICS:
BOD (Denoting Biochemical Oxygen Demand): The quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure in five (5) days at twenty degrees Celsius (20°C), expressed in milligrams per liter.
Effluent Criteria: Are defined in any applicable NPDES permit.
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: Solid wastes from the domestic and commercial preparation, cooking, and dispensing of food, and from the handling, storage and sale of food.
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: a) has a flow of fifty thousand (50,000) gallons or more per average work day; or b) has a flow greater than ten percent (10%) of the flow carried by the municipal system receiving the waste; or c) has in its waste, a toxic pollutant in toxic amounts as defined in standards issued under section 307(a) of the federal act; or d) is found by the permit issuant 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. It is 0.001 gram of the constituent in one thousand milliliters (1,000 ml) of water. It has replaced the unit formerly used commonly, parts per million, to which it is approximately equivalent, in reporting the results of water and wastewater analysis.
pH: The logarithm (base 10) of the reciprocal of the hydrogen-ion concentration expressed by one of the procedures outlined in the IEPA division of laboratories manual of laboratory methods.
ppm: Parts per million by weight.
Population Equivalent: A term used to evaluate the impact of industrial or other waste on a treatment works or stream. One population equivalent is one hundred (100) gallons of sewage per day, containing seventeen (17) pounds of BOD and twenty two (22) pounds of suspended solids.
Properly Shredded Garbage: The 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 (1/2") (1.27 centimeters) in any dimension.
Sewage: Is used interchangeably with "wastewater".
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 fifteen (15) minutes more than five (5) times the average twenty four (24) hour concentration of flows during normal operation.
Suspended Solids (SS): 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 the IEPA division of laboratories manual of laboratory methods.
Unpolluted Water: Water 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 benefited by discharge to the sanitary sewers and wastewater treatment facilities provided.
