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).

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.

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:

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:

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.

Standard methods shall mean the laboratory procedures set forth in the latest edition, at the time of analysis, of Standard Methods for the Examination of Water and Wastewater prepared and published jointly by the American Public Health Association, the American Water Works Association and The Water Pollution Control Federation.

Storm sewer means a sewer for conveying water, groundwater or unpolluted water from any source and to which sanitary and/or industrial wastes are not intentionally admitted.

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