For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
B.O.D. (BIOCHEMICAL OXYGEN DEMAND). The quantity of oxygen by weight, expressed in mg/l, utilized in the biochemical oxidation of organic matter under standard laboratory conditions for five days at a temperature of 20°C.
C.O.D. (CHEMICAL OXYGEN DEMAND). The measure of the oxygen-consuming capacity of inorganic and organic matter present in the water or wastewater, expressed in mg/l, as the amount of oxygen consumed from a chemical oxidant in a specific test but not differentiating between stable and unstable organic matter and thus not necessarily correlating with biochemical oxygen demand.
CONTROL POINT. A point of access to a course of discharge before the discharge mixes with other discharges in the public way.
INDUSTRIAL WASTE. Waste resulting from any process of industry, manufacturing, trade or business from the development of any natural resource or any mixture of waste with water or normal wastewater or distinct from normal wastewater.
INDUSTRIAL WASTE CHARGE. The charge made on those persons who discharge industrial wastes into the municipal sewerage system.
MILLIGRAMS PER LITER (mg/l). The same as parts per million and is a weight-to-volume ratio; the milligram per liter value multiplied by the factor 8.54 shall be equivalent to pounds per million gallons of water.
NORMAL DOMESTIC WASTEWATER. Wastewater, excluding industrial wastewater, discharged by a person into sanitary sewers and in which the average concentration of total suspended solids is not more than 300 mg/l and B.O.D. is not more than 250 mg/l.
pH. The logarithm (Base 10) of the reciprocal of the hydrogen ion concentration.
PUBLIC SEWER. The pipe or conduit carrying wastewater or unpolluted drainage, in which owners of abutting properties shall have the use, subject to control by the municipality.
SUSPENDED SOLIDS. Solids measured in mg/l that either float on the surface of, or are in suspension in, water, wastewater or other liquids and which are largely removable by a laboratory filtration device.
WASTEWATER. A combination of the water-carried waste from residences, business buildings, institutions and industrial establishments, together with any ground, surface and storm water that may be present.
WASTEWATER FACILITIES. All facilities for collection, pumping, treating and disposing of wastewater and industrial waste.
WASTEWATER SERVICE CHARGE. The charge on all users of the public sewer system whose wastes do not exceed, in strength, the concentration values established as representative of normal wastewater.
