For the purposes of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
ABNORMAL SEWAGE. Any industrial waste having a suspended solids or B.O.D. content in excess of that found in normal sewage but which is otherwise acceptable into a public sewer under the terms of this subchapter.
ABNORMAL SEWAGE PERMIT. A permit approved by and received from the Director permitting the discharge or deposit of abnormal sewage into a sanitary sewer upon payment of a surcharge.
ABNORMAL SEWAGE SURCHARGE. The charge levied against any person for services rendered during treatment of abnormal sanitary sewage or waste. This charge is intended to partially defray the added cost of transporting and treating abnormal sewage or waste. This charge shall be in addition to the usual monthly charge for sanitary sewerage service.
B.O.D. Biochemical oxygen demand, the quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure, as specified in Standard Methods in five days at 20 degrees Centigrade expressed as parts per million by weight (milligrams per liter).
B.O.D. STRENGTH INDEX. The measure of the biochemical oxygen demand content of sewage in parts per million (milligrams per liter).
COOLING WATER. The water discharged from any system of condensation such as air conditioning, cooling or refrigeration. COOLING WATER shall not be discharged into any public sewer unless it is unpolluted and below 150 degrees Fahrenheit.
DIRECTOR. The Superintendent of the Water Works Department, or his or her authorized representative.
GARBAGE. Solid waste from domestic or commercial preparation, cooking or dispensing of food or from the handling, storage and sale of produce.
INDUSTRIAL WASTE. Any and all liquid or waterborne waste from industrial or commercial processes and does not include domestic sewage.
INDUSTRIAL WASTE PERMIT. A permit to deposit or discharge industrial waste into any sanitary sewer in the town.
NORMAL SEWAGE. Sewage which, when analyzed, shows by weight a daily average of not more than 2,500 parts per million gallons (300 parts per million) of suspended solids and not more than 2,500 pounds per million gallons (300 parts per million) of B.O.D., and which is otherwise acceptable into a public sewer under the terms of this subchapter.
OWNER or OCCUPANT. The person, firm or public or private corporation, using the lot, parcel of land, building or premises connected to and discharging sewage, industrial wastewater or liquid, into the sanitary sewage system of the town, and who pays, or is legally responsible for the payment of, water rates or charges made against the lot, parcel of land, building or premises, if connected to the water distribution system of the town, or who would pay or be legally responsible for such payment if so connected.
PERSON. Any individual, business entity, partnership, corporation, governmental agency or political subdivision.
pH. The logarithm of the reciprocal of the weight of hydrogen ions, in grams per liter of solution, measured and calculated in accordance with Standard Methods.
POLLUTED WATER OR WASTE. Any water or liquid waste containing any of the following: phenols or other substances to an extent imparting taste and odor in receiving waters; toxic or poisonous substances in suspension, colloidal state or solution; noxious or odorous gases; more than 1,000 parts per million, by weight, of dissolved solids, of which more than 500 parts per million are chloride; more than 15 parts per million each of suspended solids and/or B.O.D.; color exceeding an objectionable limit; or having a pH value of less than 5.5 or more than 10.0 and/or any water or waste not approved for discharge into a stream or waterway by the appropriate state authority.
PROPERLY SHREDDED GARBAGE. Garbage 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. Any publicly owned sanitary sewer, storm drain or watercourse.
SANITARY SEWER. A publicly owned pipe or conduit designed to collect and transport industrial waste and domestic sewage.
SEWAGE TREATMENT PLANT. Any arrangement of devices or structures used for treating sewage.
S.S. STRENGTH INDEX. The measure of the suspended solids content of sewage in parts per million (milligrams per liter).
STANDARD METHODS. “Standard Methods for the Examination of Water and Wastewater,” prepared and published jointly by the American Public Health Association, American Waterworks Association and the Water Pollution Control Federation, 12th Edition, Second Printing, March, 1966.
STRENGTH INDEX. Both the biochemical oxygen demand index and the suspended solids strength index.
SUSPENDED SOLIDS. Solids that either float on the surface of, or in suspension in, water, sewage or other liquid and which are removable by laboratory filtering.
UNPOLLUTED WATER OR WASTE. Any water or liquid waste containing none of the following: phenols or other substances to an extent imparting taste and odor in receiving waters; toxic or poisonous substances in suspension colloidal state or solution; noxious or odorous gases; not more than 1,000 parts per million by weight, of dissolved solids, of which not more than 500 parts per million are chloride; not more than 500 parts per million are chloride; nor more than ten parts per million of each of suspended solids and B.O.D.; color not exceeding objectionable limit, nor a pH value of less than 5.5 nor higher than 10.0 and/or any water or waste approved for discharge into a stream or waterway by the appropriate state authority.
WASTEWATER. Water that has been used by and discharged from an industry, commercial enterprise, household or other water consumer, which water may be either polluted or unpolluted.
