(j) “Combined sewer” means a sewer intended to receive both wastewater and storm or surface water.
(k) “Building drain” means that part of the lowest horizontal piping of a drainage system which receives the discharge from soil, waste and other drainage pipes inside the walls of a building and conveys it to the building sewer beginning three feet outside the building wall.
(1) “Building drain - sanitary” means a building drain which conveys sanitary or industrial sewage only.
(2) “Building drain - storm” means a building drain which conveys stormwater or other clear water drainage, but no wastewater.
(l) “Building sewer” means the extension from the building to the public sewer or other place of disposal. (Also called house connection).
(1) “Building sewer - sanitary” means a building sewer which conveys sanitary or industrial sewage only.
(2) “Building sewer - storm” means a building sewer which conveys stormwater or other clear water drainage, but no sanitary or industrial sewage.
(m) “Normal domestic sewage” shall have the same meaning as defined in the Sewage Rate Ordinance.
(n) “Industrial wastes” means the liquid wastes from industrial manufacturing processes, trade, or business as distinct from sanitary sewage.
(o) “Garbage” means solid wastes from the domestic and commercial preparation, cooking, and dispensing of food, and from the handling, storage and sale of produce.
(p) “Properly shredded garbage” means 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 in any dimension.
(q) “Infiltration” means the water entering a sewer system, including building drains and sewers, from the ground, through such means as, but not limited to, defective pipes, pipe joints, connections, or manhole walls. (Infiltration does not include and is distinguished from inflow).
(r) “Inflow” means the water discharge into a 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 combined sewers, catch basins, storm waters, surface run-off, street wash waters or drainage. (Inflow does not include, and is distinguished from infiltration).
(s) “Infiltration/inflow” means the total quantity of water from both infiltration and inflow without distinguishing the source.
(t) “Biochemical Oxygen Demand” (BOD) means the quantity of oxygen expressed in mg/l, utilized in the biochemical oxidation of organic matter under standard laboratory procedures in five (5) days at 20 degrees C.
(u) “Suspended solids” (SS) means solids that either float on the surface of, or are in suspension in water, sewage, or other liquids and which are removable by laboratory filtering.
(v) “Total solids” means the sum of suspended and dissolved solids.
(w) “pH” means the reciprocal of the logarithm of the hydrogen ion concentration. The concentration is the weight of hydrogen ions, in grams per liter of solution.
(x) “Fecal coliform” means any of a number of organism common to the intestinal tract of man and animals, whose presence in sanitary sewage is an indicator of pollution.
(y) “Flotable oil” means oil, fat, or grease in a physical state, such that will separate by gravity from wastewater by treatment in a pretreatment facility approved by the Village.
(z) “Toxic amount” means concentrations of any pollutant or combination of pollutants, which upon exposure to or assimilation into any organism will cause adverse effects, such as cancer, genetic mutations, and physiological manifestations, ad defined in standards issued pursuant to Article 307(a) of PL 92- 500.
(aa) “Slug” means 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 fifteen minutes more than five times the average twenty-four hour concentration or flows during normal operation and shall adversely effect the collection system.
(bb) “Unpolluted water” is water of 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 benefitted by discharge to the sanitary sewers and wastewater treatment facilities provided.
(cc) “Compatible pollutant” means biochemical oxygen demand, suspended solids, pH, and fecal coliform bacteria, plus additional pollutants identified in the NPDES Permit if the treatment works was designed to treat such pollutants, and in fact does remove such pollutants to a substantial degree. The term substantial degree is not subject to precise definition, but generally contemplates removals in the order of eighty percent (80%) or greater. Minor incidental removals in the order of ten percent (10%) are not considered substantial. Examples of the additional pollutants which may be considered compatible include:
(1) Chemical oxygen demand,
(2) Total organic carbon,
(3) Phosphorus and phosphorus compounds,
(4) Nitrogen and nitrogen compounds, and
(5) Fats, oils, and greases of animal and vegetable origin.
(except as prohibited where these materials would interfere with the operation of the treatment works.
(dd) “Incompatible pollutant” means any pollutant that is not defined as a compatible pollutant, including non-biodegradable dissolved solids.
