INFLOW: The water discharged into a sanitary sewer system, including building drains and sewers, from such sources as, but not limited to, roof leaders; cellar, yard and area drains; foundation drains; unpolluted cooling water discharges; drains from springs and swampy areas; manhole covers; cross-connections from storm sewers; and/or combined sewers, catch basins, stormwaters, surface runoff, street wash waters or drainage. Inflow does not include, and is distinguished from, infiltration.

LICENSED DISPOSER: A person or business holding a valid license to do septage servicing under Ch. NR 113, Wis. Adm. Code.

MUNICIPALITY: The Village of Belgium.

NATURAL OUTLET: Any outlet, including storm sewers and combined sewer overflows, into a watercourse, pond, ditch, lake or other body of surface or ground water.

NITROGEN: Ammonia nitrogen, expressed in milligrams per liter of NHN. Quantitative determination of ammonia nitrogen shall be made in accordance with procedures set forth in Standard Methods.

NORMAL DOMESTIC STRENGTH WASTEWATER: Wastewater with concentrations of biochemical oxygen demand (BOD), suspended solids (SS) and phosphorus (P) no greater than the concentrations identified in the current user charge system.

OPERATION AND MAINTENANCE COSTS: All costs incurred in the operation and maintenance of the Village wastewater treatment facilities. Notwithstanding other accounting procedures as may be used by the Village for other purposes, in the context of this article, this class of costs shall be understood to include equipment replacement costs and shall be understood to exclude depreciation charges and debt retirement.

PARTS PER MILLION (ppm) [also milligrams per liter (ml)]: A weight to weight ratio. The parts per million value multiplied by the factor of 8.345 shall be equivalent to pounds per million gallons of water.

PERSON: Any and all persons, including any individual, firm, company, municipality or private corporation, association, society, institution, enterprise, governmental agency or other entity.

pH: The logarithm of the reciprocal of the hydrogen ion concentration. The concentration is the weight of the hydrogen ion, in grams, per liter of solution. Neutral water, for example, has a pH value of seven and a hydrogen-ion concentration of 10.

PHOSPHORUS (P): The element of that same name, the concentration of which, in wastewater, is ascertained by the test for total phosphorus and is expressed in milligrams per liter of P, as defined in the Standard Methods.

PRETREATMENT: The reduction of the amount of pollutants, the elimination of pollutants or the alteration of the nature of pollutant properties in wastewater prior to or in lieu of discharge in or otherwise introducing such pollutants into a wastewater system.

PRIVATE SEWER: A sewer which is not owned by the Village or Utility.

PUBLICLY OWNED TREATMENT WORKS (POTW): A treatment works, including any devices and systems used in the storage, treatment, recycling and reclamation of municipal and industrial waste.
