A. From the noncommercial preparation, cooking or handling of food; or
B. Containing human excrement and similar matter discharged from the sanitary facilities of dwellings, commercial buildings, industrial facilities and institutions and other places where humans congregate.
GARBAGESolid wastes from the handling, preparation, cooking, dispensing or storage of food.
GROUND GARBAGEThe residue from the preparation, cooking or dispensing of food that has been shredded to such degree that all particles will be carried freely in suspension under the flow conditions normally prevailing in public sewers, with no particle greater than 1/2 inch in any dimension.

SANITARY SEWAGEA combination of water-carried wastes from residences, business buildings, institutions and industrial plants (other than industrial wastes from such plants) together with such groundwater, surface water or stormwater as may be present.
SANITARY SEWERA sewer which carries wastewater and to which stormwater, surface water and groundwater are not intentionally admitted.
SIGNIFICANT INDUSTRIAL USERAny industrial user of the wastewater treatment system whose flow exceeds 10,000 gallons per day, or 5% of the daily capacity of the treatment system, or contains:
A. Greater than normal wastewater concentration; or
SLUGAny discharge of sewage or industrial waste which in concentration of any given constituent exceeds more than five times the average twenty-four-hour concentration during normal operation.
STANDARD METHODSThe examination and analytical procedures set forth in the most recent edition of "Standard Methods for the Examination of Water, Sewage and Industrial Waste" published by the American Public Health Association, the American Water Works Association and the Federation of Sewage and Industrial Waste Associations.
STORMWATERAny flow occurring during or following any form of natural precipitation and resulting therefrom.
SUPERINTENDENTThe person or persons designated by the Village of Rothschild Board to supervise the operation of the treatment plant and system.
SUSPENDED SOLIDSThe total suspended matter that floats on the surface of or is suspended in water, wastewater or other liquids, a high percentage of which is removable by laboratory filtering. Measurement of quantities of suspended solids shall be made in accordance with procedures set forth above in the definition of "Standard Methods."
SYSTEMAny publicly owned devices, facilities, structures, equipment or works used for the purpose of the transmission, storage, treatment, recycling and reclamation of industrial and domestic wastes or necessary to recycle or reuse the water at the most economical cost over the estimated life of the system, including intercepting sewers; outfall sewers; sewage collection systems; pumping, power and other equipment and their appurtenances; extensions, improvements, remodeling, additions and alterations 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 of residues resulting from such treatment.
UNPOLLUTED WATERWater free from pollutants in excess of the quantities limited or prohibited by the federal, state or local effluent standards in effect or water whose discharge will not cause any violation of federal, state or local receiving water quality standards.
USERAny person who discharges or causes or permits the discharge of wastewater into the wastewater treatment system.
USER CHARGEA charge levied on users of the wastewater collection and treatment facilities for payment of operation and maintenance costs, debt service and cash reserve.
[Added 9-28-1987]
USER CLASSIFICATIONA classification of users based on the 1972 (or subsequent) edition of the Standard Industrial Classification (SIC) Manual prepared by the U.S. Office of Management and Budget.
