For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
APPROVING AUTHORITY. The Town Engineer or other official designated by the Mayor or his or her duly authorized deputy, agent or representative.
BOD (DENOTING “BIOCHEMICAL OXYGEN DEMAND”). The quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure in five days at 20°C, expressed in parts per million. The laboratory determination shall be made in accordance with the procedures set forth in Standard Methods.
BUILDING DRAIN. The part of the lowest horizontal piping of a drainage system which receives the discharges from soil, waste and other drainage pipes inside the walls of the building and conveys them to the building sewer beginning three feet outside the inner face of the building wall.
BUILDING SEWER. The extension from the building drain to the sewer or other place for disposal.
DOMESTIC SEWAGE. Waterborne wastes normally discharged from the sanitary conveniences of dwellings (including apartment houses and hotels), office buildings, factories and institutions, free from stormwater, surface water and industrial wastes.
GARBAGE. Solid wastes and residue from the preparation, cooking and dispensing of food and from the handling, storage and sale of food products and produce.
INDUSTRIAL WASTES. All waterborne solids, liquids or gaseous wastes resulting from any industrial, manufacturing or food processing operation or process or from the development of any natural resource, or any mixture of these with water or domestic sewage as distinct from normal domestic sewage.
NATURAL OUTLET. Any outlet into a watercourse, pond, ditch, lake or other body of surface or ground water.
NORMAL DOMESTIC SEWAGE. Normal sewage for the town in which concentration of suspended materials and five-day 20°C. BOD is established at 240 parts per million each, by weight, on the basis of the normal daily contribution of 0.20 pounds per capita, per 100 gallons.
PARTS PER MILLION. A weight-to-weight ratio; the parts per million value multiplied by the factor 8,345 shall be equivalent to pounds per million gallons of water.
PERMITTEE. The person applying for a permit to construct a sanitary sewer main or to connect to an existing sanitary sewer.
pH. The logarithm (base 10) of the reciprocal of the hydrogen ion concentration of a solution. It shall be determined by one of the procedures outlined in Standard Methods.
PROPERLY SHREDDED GARBAGE. The wastes from the preparation, cooking and dispensing of food that have been shredded to such a degree that all particles will be carried under the flow conditions normally prevailing in public sewers, with no particle greater than one-half inch in any dimension.
PUBLIC SEWER. Either a sanitary or storm sewer in which all owners of abutting properties shall have equal rights and is controlled by a public authority.
SANITARY SEWER. A sewer which carries sewage and to which storm, surface and ground waters are not intentionally admitted.
SEWAGE. A combination of water-carried waste from residences, business buildings, institutions and industrial establishments, together with such ground, surface and storm waters as may be present.
SEWAGE TREATMENT PLANT. Any arrangement of devices and structures used for treating sewage.
SEWAGE WORKS. All facilities for collecting, pumping, treating and dispensing of sewage.
SEWER. A pipe or conduit for carrying sanitary sewage.
SEWERAGE. The system of sewers and appurtenances for the collection, transportation and pumping of sewage and industrial wastes.
SEWER SERVICE CHARGE. The charge made on all users of the public sewerage system whose wastes do not exceed in strength the concentration values established as representative of normal sewage.
SLUDGE. Any discharge of water, sewage or industrial waste which in concentration of any given constituent or in quantity of flow exceeds for any period of duration longer than 15 minutes more than five times the average 24-hour concentration or flows during normal operation.
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 OR STORM DRAIN. A sewer which carries storm and surface waters and drainage, but excludes sewage and polluted industrial wastes.
STORMWATER RUNOFF. The portion of the rainfall that is drained into the storm sewers.
SURCHARGE. The charge in addition to the published water and sewer rates. The basis for SURCHARGES on industrial wastes is a capital and operating cost for suspended solids, BOD and chlorine demand exceeding normal domestic sewage.
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. Quantitative determination of SUSPENDED SOLIDS shall be made in accordance with procedures set forth in Standard Methods.
UNPOLLUTED WATER OR WASTE. Any water or waste containing none of the following: free or emulsified grease or oil, acid or alkali, phenols or other substances imparting taste and odor in the receiving water; toxic poisonous substances in suspension, colloidal state or solution; and noxious or odorous gases. It shall contain not more than ten parts per million each of suspended solids and BOD. The color shall not exceed 150 Jackson turbidity units.
WATERCOURSE. A channel in which a flow of water occurs, either continuously or intermittently.
