The following words, terms and phrases, when used in this article, shall have the meanings ascribed to them in this section, except where the context clearly indicates a different meaning:

Biochemical oxygen demand or BOD means the quantity of oxygen expressed in mg/l, utilized in the biochemical oxidation of organic matter under standard laboratory procedures on five (5) days at twenty (20) degrees Celsius.

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 the building and conveys it to the building sewer beginning three (3) feet outside the building wall.

Building drain, sanitary means a building drain which conveys sanitary or industrial sewage only.

Building drain, storm means a building drain which conveys stormwater or other clearwater drainage, but no wastewater.

Building sewer (also called house connection) means the extension from the building drain to the public sewer or other place of disposal.

Building sewer, storm means building sewer which conveys stormwater or other clearwater drainage, but no sanitary or industrial sewage.

Combined sewer means a sewer intended to receive both wastewater and storm and/or surface water.

Combined sewer, sanitary means a building sewer which conveys sanitary or industrial sewage only.

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 (80) percent or greater. Minor incidental removals in the order of ten (10) to thirty (30) percent which are not considered compatible include, chemical oxygen demand, total organic carbon, phosphorus and phosphorous compounds, nitrogen and nitrogen compounds, fats, oils, and greases of animal or vegetable origin (except as prohibited where these materials would interfere with the operation of the treatment works).

Easements means an acquired legal right for the specific use of land owned by others.

Fecal coliform bacteria means any of a number of organisms common to the intestinal tract of man and animals, whose presence in sanitary sewage is an indicator of pollution.

Floatable oil means oil, fat, or grease in a physical state, such that it will separate by gravity from wastewater by treatment in a pretreatment facility approved by the Town.

Garbage means solid wastes from the domestic and commercial preparation, cooking, and dispensing of food, and from the handling, storage and sale of produce.

Incompatible pollutant means any pollutant that is not defined as a compatible pollutant, including nonbiodegradable dissolved solids.

Industrial wastes means the liquid wastes from industrial manufacturing processes, trade, or business as distinct from sanitary sewage.

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.

Infiltration/inflow means the total quantity of water from both infiltration and inflow without distinguishing the source.

Inflow means the water discharged not a sewer system, including building drains and sewers, from such sources as, but not limited to: roof leaders, cellars 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, stormwaters, surface run-off, street wash waters or drainage. "Inflow" does not include, and is distinguished from infiltration.

Inspector means the person or persons duly authorized by the Town, through its board of trustees, to inspect and approve the installation of building sewers and their connection to the public sewer system.

Major contributing industry means an industry that:

1. Has a flow of fifty thousand (50,000) gallons or more per average work day;

2. Has a flow greater than five (5) percent of the flow carried by the municipal system receiving the waste;

3. Has in its waste a toxic pollutant in toxic amounts as defined in standards issued under section 307(a) of PL 92-500;

4. Has a significant impact, either singly or in combination with other contributing industries, on a treatment works or on the quality of effluent from that treatment works.

NPDES permit means a permit issued under the national pollutant discharge elimination system for discharge of wastewaters to the navigable waters of the United States pursuant to section 402 of PL 92-500.

Natural outlet means outlet, including storm sewers and combined sewer overflows, into a watercourse, pond, ditch, lake or other body of surface or ground water.

Normal domestic sewage shall have the meaning assigned to it in section 19-126.

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.

Person means any person discharging any wastewater to the wastewater treatment works.

Pretreatment means the treatment of industrial sewage from privately owned industrial sources prior to introduction into a public treatment works.

Private sewer means a sewer which is not owned by a public authority.

Properly shredded garbage means the waste from the preparation, cooking, and dispensing of food that has 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.

Public sewer means a sewer which is owned and controlled by the public authority and will consist of the following increments:

1. Collector sewer, which means a sewer whose primary purpose is to collect wastewaters from individual point source discharges.

2. Interceptor sewer, which means a sewer whose primary purpose is to transport wastewater from collector sewers to a treatment facility.

3. Force main, which means a pipe in which wastewater is carried under pressure.

4. Pumping station, which means a station positioned in the public sewer system at which wastewater is pumped to a higher level.

Sanitary sewer means a sewer which carries sanitary and industrial wastes, and to which storm, surface, and ground water are not intentionally admitted.

Sewage means the combination of the liquid and water-carried wastes from residences, commercial buildings, industrial plants and institutions, (including polluted cooling water). The three (3) most common types of sewage are:

1. Sanitary sewage, which means the combination of liquid and water-carried wastes discharged from toilet and other sanitary plumbing facilities.

2. Industrial sewage, which means a combination of liquid and water-carried wastes, discharged from any industrial establishment, and resulting from any trade or process carried on in that establishment (this shall include the wastes from pretreatment facilities and polluted cooling water).

3. Combined sewage, which means wastes including sanitary sewage, industrial sewage, stormwater, infiltration and inflow carried to the wastewater treatment facilities by a combined sewer.

Sewerage works means the structures, equipment and processes to collect, transport and treat domestic and industrial wastes and dispose of the effluent and accumulated residual solids.

Sewer means a pipe or conduit for carrying sewage.

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 ten (10) minutes more than three (3) times the average twenty-four-hour concentration or flows during normal operation and shall adversely affect the collection system.

Superintendent means the superintendent of the municipal sewage works of the Town or his authorized deputy, agent or representative.

Suspended solids 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.

Total solids means the sum of suspended and dissolved solids.

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, as defined in standards issued pursuant to section 307(a) of PL 92-500.

Unpolluted water means water of quality equal to or better than the effluent criteria in effect, or water that would not cause violation of receiving water quality standard and would not be benefited by discharge to the sanitary sewers and wastewater treatment facilities provided.
