For the purpose of this chapter, the following definitions apply unless the context clearly requires a different meaning.
APPROVING AUTHORITY. The Public Works Authority or its duly-authorized representative.
BOD or BIOCHEMICAL OXYGEN DEMAND. The quantity of oxygen by weight, expressed in milligrams per liter, which is utilized in the biochemical oxidation of organic matter under standard laboratory conditions for five days at a temperature of 20°C.
BUILDING SEWER. The extension from the building drain to the public sewer or other place of disposal, also called HOUSE LATERAL and HOUSE CONNECTION.
COD or CHEMICAL OXYGEN DEMAND. A measure of the oxygen-consuming capacity of inorganic and organic matter present in the water or wastewater, expressed in milligrams per liter, 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 MANHOLE. A manhole giving access to a building sewer at some point before the building sewer discharge mixes with other discharges in the public sewer.
CONTROL POINT. A point of access to a course of discharge before the discharge mixes with other discharges in the public sewer.
GARBAGE. Animal and vegetable wastes and residue from the preparing, cooking and dispensing of food, and from the handling, processing, storing and selling of food products and produce.
INDUSTRIAL WASTE. Waste resulting from any process of industry, manufacturing, trade or business from the development of any natural resource, or any mixture of such 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 town sewerage system.
MILLIGRAMS PER LITER or mg/l. The same as parts per million, and is a weight-to-volume ratio; the MILLIGRAM PER LITER value multiplied by the factor 8.34 shall be equivalent to pounds per million gallons of water.
NATURAL OUTLET. Any outlet into a watercourse, ditch, lake or other body of surface water or groundwater.
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 200 milligrams per liter and the BOD is not more than 200 milligrams per liter.
OVERLOAD. The imposition of organic or hydraulic loading on a treatment facility in excess of its engineered design capacity.
PERSON. A corporation, organization, government or governmental subdivision or agency, business trust, estate, trust, partnership, association or any other legal entity.
pH. The logarithm, base ten, of the reciprocal of the hydrogen ion concentration.
PUBLIC SEWER. A pipe or conduit carrying wastewater or unpolluted drainage in which the owners of abutting properties shall have the use, subject to control by the town.
SANITARY SEWER. A public sewer which conveys domestic wastewater, industrial wastes or a combination of both, and into which stormwater, surface water, groundwater and other unpolluted wastes are not intentionally passed.
SLUG. Any discharge of water, wastewater or industrial waste which in concentration of any given constituent or in quantity of flow exceeds more than five times the average 24-hour concentration or flow during normal operation for any period of duration longer than 15 minutes.
STANDARD METHODS. The examination and analytical procedures set forth in the latest edition, at the time of analysis, of Standard Methods for the Examination of Water and Wastewater as prepared, approved and published jointly by the American Public Health Association, the American Water Works Association and the Water Pollution Control Federation.
STORM SEWER. A public sewer which carries stormwater, surface water and drainage and into which domestic wastewater or industrial wastes are not intentionally passed.
STORMWATER. Rainfall or any other form of precipitation.
SUPERINTENDENT. The Water and Wastewater Superintendent of the town or his or her duly- authorized deputy, agent or representative.
SUSPENDED SOLIDS. Solids, measured in milligrams per liter, which 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.
TO DISCHARGE. To deposit, conduct, drain, emit, throw, run, allow to seep or otherwise release or dispose of, or to allow, permit or suffer any of these acts or emissions.
TRAP. A device designed to skim, settle or otherwise remove grease, oil, sand, flammable wastes or other harmful substances.
UNPOLLUTED WASTEWATER. Water containing:
(1) No free or emulsified grease or oil;
(2) No acids or alkalies;
(3) No phenols or other substances producing taste or odor in the receiving water;
(4) No toxic or poisonous substances in suspension, colloidal state or solution;
(5) No noxious or otherwise obnoxious or odorous gases;
(6) Not more than an insignificant amount, in milligrams per liter, each of suspended solids and BOD, as determined by the State Health Department; and
(7) Color not exceeding 50 units as measured by the platinum-cobalt method of determination as specified in Standard Methods.
WASTE. Rejected, unutilized or superfluous substances in liquid, gaseous or solid form resulting from domestic, agricultural or industrial activities.
WASTEWATER. A combination of the water-carried wastes from residences, business buildings, institutions and industrial establishments together with any groundwater, surface water and stormwater which may be present.
WASTEWATER FACILITIES. Includes all facilities for collecting, pumping, treating and disposing of wastewater and industrial wastes.
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.
WASTEWATER TREATMENT PLANT. Any town-owned facilities, devices and structures used for receiving, processing and treating wastewater, industrial waste and sludge from the sanitary sewers.
WATERCOURSE. A natural or human-made channel in which a flow of water occurs, either continuously or intermittently.
