COMBINED SEWER. A sewer intended to serve as a sanitary sewer and a storm sewer or as an industrial sewer and a storm sewer.
DOMESTIC or SANITARY WASTE. Wastewater that is primarily produced by residential users with BOD concentration less than 225 milligrams per liter as distinct from industrial waste and the characteristics as stated in the definition for WATERCOURSE. The wastewater does not include infiltration and/or inflow, and it is composed of domestic wastewater.
EASEMENT. An acquired legal right for the specific use of land owned by others.
FLOATABLE OIL. Oil, fat or grease in a physical state such that it will separate by gravity from wastewater by treatment in an approved pretreatment facility. All wastewater shall be considered free of floatable fat if it is properly pretreated and the wastewater does not interfere with the collection system.
GARBAGE. The animal and vegetable waste resulting from the handling, preparation, cooking and serving of foods.
INCOMPATIBLE WASTE. Waste that either singly or by interaction with other wastes interferes with any waste treatment process, constitutes a hazard to humans or animals, creates a public nuisance
or creates any hazard in the receiving waters of the wastewater treatment works.
INDUSTRIAL USERS or INDUSTRIES.
(1) Entities that discharge into a publicly owned wastewater treatment works, liquid wastes resulting from the process employed in industrial or manufacturing processes or from the development of any natural resources are identified in the Standard Industrial Classification Manual, 1972, Office of Management and Budget, as amended and supplemented under one of the following divisions.
(a) Division A: Agriculture, Forestry and Fishing;
(b) Division B: Mining;
(c) Division D: Manufacturing;
(d) Division E: Transportation, Communications, Electric, Gas and Sanitary Sewers;
(e) Division I: Services.
(2) For the purpose of this definition, domestic or sanitary waste shall be considered to have the following characteristics: BOD5, less than 225 mg/l; suspended solids, less than 215 mg/l.
(3) Any nongovernmental user of a publicly owned treatment works which discharges wastewater to the treatment works which contains toxic pollutants or poisonous solids, liquids or gases in sufficient quantity either singly or by interaction with other wastes to contaminate the sludge of any municipal systems or to injure or to interfere with any sewage treatment process or which constitutes a hazard to humans or animals, creates a public nuisance or creates any hazard in or has an adverse effect on the waters receiving any discharge from the treatment facilities.
INDUSTRIAL WASTES. Wastewater discharged by industry that includes solid, liquid or gaseous waste resulting from the industrial or manufacturing process, trade or business or from the development, recovery or processing of natural resources.
INFILTRATION. The water entering the sanitary sewer system and service connections 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 discharged into the sanitary sewer system from such sources as, but not limited to, roof leaders, cellar, yard and area drains, foundation drains, cooling water discharges, drains from springs and swampy areas, manhole covers, cross connections to storm sewers, catch basins, stormwaters, surface run-off, street wash waters or drainage. INFLOW does not include, and is distinguished from, infiltration.
INTERCEPTOR SEWER. A sewer whose primary purpose is to transport wastewaters from collector sewers to a treatment facility.
MAY. Permissive.
NATURAL OUTLET. Any outlet, including storm sewers and combined sewer overflows, into a watercourse, pond, ditch, lake or other body of surface or ground water.
NPDES PERMIT (NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM PERMIT). The system for issuing, conditioning and denying permits for the discharge of pollutants from point sources into the navigable waters, the contiguous zone and the oceans by the Environmental Protection Agency pursuant to the Federal Water Pollution Control Act of 1972, Sections 402 and 405.
PERSON. Any individual, firm, company, association, society, corporation or group.
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. Neutral water, for example, has a pH value of 7 and a hydrogen-ion concentration of 10 (where = 7).
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 freely under the flow conditions normally prevailing in public sewers with no particle greater than one-half inch (1.27 centimeters) in any dimension.
PUBLIC SEWER. A common sewer controlled by the city.
RESIDENTIAL, COMMERCIAL AND INSTITUTIONAL/GOVERNMENTAL USERS. All non- industrial users.
SANITARY SEWER. A sewer intended to carry only sanitary or sanitary and industrial wastewater from residences, commercial buildings, industrial plants and institutions, together with minor quantities of ground, storm and surface waters that are not admitted intentionally.
SEWAGE. The spent water of a community. The preferred term is WASTEWATER.
SEWER. A pipe or conduit that carries wastewater or drainage water.
SHALL. Mandatory.
SLUG. Any discharge of water or wastewater which in concentration of any given constituent or 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 and shall adversely affect the collection system and/or performance of the water reclamation plant.
STORM DRAIN (sometimes termed STORM SEWER). A drain or sewer intended to carry storm waters, surface runoff, groundwater, sub-surface water, street wash water, drainage and unpolluted water from any source.
SUPERINTENDENT. The Utilities Superintendent or his or her authorized deputy, agent or representative.
SUSPENDED SOLIDS. Total suspended matter that either floats on the surface of, or is in suspension in, water, wastewater or other liquids and that is removable by laboratory filtering as prescribed in “Standard Methods for the Examination of Water and Wastewater” and referred to as non-filterable residue.
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.
WASTEWATER. The spent water of a community. From the standpoint of source, it may be a combination of the liquid and water carried wastes from residences, commercial buildings, industrial plants and institutions, together with any groundwater, surface water and stormwater (infiltration/inflow) that are not admitted intentionally.
WASTEWATER FACILITIES. The structures, equipment and processes required to collect, carry away and treat domestic and industrial wastes and dispose of the effluent.
WASTEWATER TREATMENT WORKS or TREATMENT WORKS. An arrangement of devices and structures for treatment of wastewater, industrial waste and sludge. Sometimes used as synonymous for WASTEWATER TREATMENT PLANT or WASTE TREATMENT PLANT or WATER POLLUTION CONTROL PLANT or SEWAGE TREATMENT PLANT.
WATERCOURSE. A natural or artificial channel for the passage of water either continuously or intermittently.
WPCF. The Water Pollution Control Federation.
