BUILDING DRAIN, SANITARY. A building drain which conveys sanitary or industrial sewage only.
BUILDING DRAIN, STORM. A building drain which conveys storm water or other clear water drainage, but no wastewater.

BUILDING SEWER, STORM. A building sewer which conveys storm waste or other clear water drainage, but no sanitary or industrial sewage.
COMBINED SEWER. A sewer intended to receive both wastewater and storm or surface water.
COMPATIBLE POLLUTANT. 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 the pollutants, and in fact does remove the pollutants to a substantial degree. The term "substantial degree" is not subject to precise definition, but generally contemplates removals in the order of 80% or greater. Minor incidental removals in the order of 10% to 30% 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 compound; and
(5) Fats, oils and greases of animal or vegetable origin (except as prohibited where these materials would interfere with the operation of the treatment works).
EASEMENT. An acquired legal right for the specific use of land owned by others.
FECAL COLIFORM. Any of a number of organisms common to the intestinal tract of humans and animals, whose presence in sanitary sewage is an indicator of pollution.
FLOATABLE OIL. Oil, fat or grease in a physical state, so that it will separate by gravity from wastewater by treatment in a pretreatment facility approved by the town.
GARBAGE. Solid wastes from the domestic and commercial preparation, cooking and dispensing of food, and from the handling, storage and sale of produce.
INCOMPATIBLE POLLUTANT. Any pollutant that is not defined as a compatible pollutant, including non-biodegradable dissolved solids.
INDUSTRIAL WASTES. The liquid wastes from industrial manufacturing processes, trade or business as distinct from employee wastes or wastes from sanitary conveniences.
INFILTRATION. 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. The total quantity of water from both infiltration and inflow without distinguishing the source.
INFLOW. 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.)
INSPECTOR. The person or persons duly authorized by the town, through its Town Council, to inspect and approve the installation of building sewers and their connection to the public sewer system.
MAJOR CONTRIBUTING INDUSTRY. An industry that:
(1) Has a flow of 50,000 gallons or more per average work day;
(2) Has a flow greater than 5% 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 42 U.S.C. §§ 300f et seq.; or
(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.
MAY. The act referred to is permissive.
NATURAL OUTLET. Any outlet, including storm sewers and combined sewer overflows, into a watercourse, pond, ditch, lake or other body of surface or groundwater.
NH3N. The same as AMMONIA NITROGEN MEASURED AS NITROGEN. The laboratory determinations shall be made in accordance with procedures set forth in Standard Methods, as defined herein.
NORMAL DOMESTIC SEWAGE. The same meaning as defined in § 53.30.
NPDES PERMIT. A permit issued under the National Pollutant Discharge Elimination System for discharge of wastewaters to the navigable waters of the United States pursuant to 33 U.S.C. § 1342.
P(or PHOSPHORUS). The chemical element Phosphorus.
pH. 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. Any individual, firm, company, association, society, limited liability company, trust, estate, corporation, group or other entity.
PRETREATMENT. The treatment of industrial sewage from privately owned industrial sources prior to introduction into a public treatment works.
PRIVATE SEWER. A sewer which is not owned by a public authority.
PROPERLY SHREDDED GARBAGE. The wastes from the preparation, cooking and dispensing of food that has been shredded to 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. A sewer which is owned and controlled by the public authority and will consist of the following increments.
(1) COLLECTOR SEWER. A sewer whose primary purpose is to collect wastewaters from individual point source discharges.
(2) FORCE MAIN. A pipe in which wastewater is carried under pressure.
(3) INTERCEPTOR SEWER. A sewer whose primary purpose is to transport wastewater from collector sewers to a treatment facility.
(4) PUMPING STATION. A station positioned in the public sewer system at which wastewater is pumped to a higher level.
SANITARY SEWER. A sewer which carries sanitary and industrial wastes, and to which storm, surface and ground water are not intentionally admitted.
SEWAGE. The combination of liquid and water-carried wastes from residences, commercial buildings, industrial plants and institutions (including polluted cooling water). The three most common types of sewage are:
(1) COMBINED SEWAGE. Wastes including sanitary sewage, industrial sewage, storm water, infiltration and inflow carried to the wastewater treatment facilities by a combined sewer;
(2) INDUSTRIAL SEWAGE. 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); and
(3) SANITARY SEWAGE. The combination of liquid- and water-carried wastes discharged from toilet and other sanitary plumbing facilities.
SEWAGE WORKS. The structures, equipment and processes to collect, transport and treat domestic and industrial wastes and dispose of the effluent and accumulated residual solids.
SEWER. A pipe or conduit for carrying sewage.
SHALL. The act referred to is mandatory.
SLUG. 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 minutes more than three times the average 24 hours' concentration of flows during normal operation and shall adversely affect the collection system.
STANDARD METHODS. 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. A sewer for conveying water, ground water or unpolluted water from any source and to which sanitary and/or industrial wastes are not intentionally admitted.
SUPERINTENDENT. The Superintendent of the municipal sewage works of the town or his or her authorized deputy, agent or representative.
SUSPENDED SOLIDS. 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 under standard laboratory procedure.
TOTAL SOLIDS. The sum of suspended and dissolved solids.
TOXIC AMOUNT. 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 33 U.S.C. § 1317(a).
UNPOLLUTED WATER. 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.
