For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
BOD or 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 milligrams per liter.
BUILDING DRAIN. Horizontal piping within or under a building, installed below the lowest fixture or the lowest floor level from which fixtures can drain by gravity to the building sewer.
BUILDING INSPECTOR. The Building Inspector of the village or that person’s appointed assistant, agent, or representative.
BUILDING SEWER. The part of the drain system not within or under a building, which conveys its discharge to a public sewer, private interceptor main sewer, private sewage system, or other point of disposal.
CLEAR WATER WASTES. Liquids other than stormwater, having no impurities or wherein impurities are below a minimum concentration considered harmful by the State Department of Natural Resources, including, but not limited to, non-contact cooling water and condensate drainage from refrigeration compressors and air conditioning equipment, drainage of water used for equipment chilling purposes, and cooled condensate from steam heating systems or other equipment.
DEBT SERVICE. Costs to the Sewer Department for the retirement of debts incurred in the provision of wastewater facilities, and including both principal and interest.
FLOATABLE OIL. Oil, fat, or grease in such a physical state that it will separate by gravity from wastewater in an approved pretreatment facility. A wastewater shall be considered free of FLOATABLE OIL if it is properly pretreated and the wastewater does not interfere with the collection system.
HOLDING TANK. An approved watertight receptacle for the collection and holding of sewage.
INDUSTRIAL USER.
(1) (a) Any non-governmental, non-residential user of a publicly-owned treatment works which discharges more than the equivalent of 1,000 gallons per day (gpd) of sanitary waste and which is identified in the most recent edition of the Standard Industrial Classification Manual, or its successor manual, under one of the following divisions:
1. Division A: Agriculture, Forestry, and Fishing;
2. Division B: Mining;
3. Division D: Manufacturing;
4. Division E: Transportation, Communications, Electric, Gas, and Sanitary Services; or
5. Division I: Services.
(b) In determining the amount of a user’s discharge, the village will exclude domestic waste or discharges from sanitary conveniences.
(c) After applying the sanitary waste exclusion in division (1)(b) of this definition, discharges in the above divisions that have a volume exceeding 1,000 gpd of the weight of biochemical oxygen demand (BOD) or suspended solids (SS) equivalent to that weight found in 1,000 gpd of sanitary waste are considered INDUSTRIAL USERS. Sanitary waste, for purposes of this calculation of equivalency, shall be wastes of normal concentration as defined in this chapter.
(2) Any non-governmental user who discharges wastewater to the village’s sewers, which wastewater contains toxic pollutants or poisonous solids, liquids, or gases in sufficient quantity either singly or by interaction with other waste, to contaminate the sludge of the municipal sewer systems, or to injure or to interfere with any sewage treatment process, or which constitutes a hazard to animals, creates a public nuisance, or creates any hazard in or has an adverse effect on the waters receiving any discharge from the treatment works.
INDUSTRIAL WASTES. Wastes discharged by industrial users.
LICENSED DISPOSER. Any person servicing septic and holding tanks, dosing chambers, grease interceptors, seepage beds, seepage pits, seepage trenches, privies, or portable restrooms who holds a valid state sanitary license.
MAY. The act referred to is permissive.
NATURAL OUTLET. Any outlet into a watercourse, pond, ditch, lake, or other body of surface or ground water.
NORMAL CONCENTRATION.
(1) Five-day 20°C, BOD of not more than 200 mg/L; and
(2) A suspended solids content of not more than 200 mg/L.
NORMAL WASTEWATER. Wastewater in which BOD or suspended solids concentrations do not exceed normal concentrations.
OPERATION AND MAINTENANCE COSTS. Costs to the Sewer Department for the provision of labor, utilities, supplies, equipment maintenance, and other normal costs necessary for the provision of sewage service including both the collection system and treatment facilities.
PERSON. Any individual, firm, company, municipal or private corporation, association, society, institution, enterprise, governmental agency, or other entity.
pH. The logarithm (base ten) of the reciprocal of the hydrogen ion concentration expressed in moles per liter.
PORTABLE RESTROOM. Fixtures, incorporating holding tank facilities, designed to directly receive human excrement. PORTABLE RESTROOMS are self-contained units, may be designed for one or more person’s use at a given time, and are readily transportable. PORTABLE RESTROOM wastewater shall be disposed of as holding tank wastewater.
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 ½-inch (1.27 centimeters) in any dimension.
PUBLIC SEWER. A sewer owned and controlled by public authority and in which all owners of abutting properties have equal rights.
REPLACEMENT COSTS. Expenditures for purchasing and installing equipment, accessories, or appurtenances which are necessary to maintain the capacity and performance during the service life of the treatment works for which those works were designed and constructed.
SANITARY SEWER. A sewer that carries liquid and water-carried wastes from residences, commercial buildings, industrial plants, and institutions.
SEPTAGE. The wastewater or contents of septic or holding tanks, dosing chambers, grease interceptors, seepage beds, seepage pits, seepage trenches, privies, or portable restrooms.
SEPTIC TANK. A tank which receives and partially treats sewage through processes of sedimentation, oxidation, flotation, and bacterial action so as to separate solids from the liquid in the sewage and discharges the liquid to a soil absorption system. Typically the tank must be pumped every two to three years. Tanks that are pumped more frequently than once every six months are in effect operating like a holding tank and the wastewater shall be disposed of as holding tank wastewater.
SEWAGE. The spent water of a community. The preferred term is WASTEWATER.
SEWER DEPARTMENT or DEPARTMENT. The Village Sewer Department.
SEWER. A pipe or conduit for carrying wastewater.
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 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 wastewater treatment works.
STORM SEWER. A sewer which carries storm surface waters, and unpolluted (clear) cooling water drainage, but excludes domestic and industrial wastewater.
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 and referred to as nonfilterable residue.
USER CHARGE. A charge levied on users of wastewater treatment works and the sanitary sewer collection system for the cost of provision of facilities and service including operation and maintenance, replacement cost, debt service, and other related costs for those facilities.
UTILITY. The Sewer Department of the village.
VILLAGE. The Village of Linden, Wisconsin.
WASTEWATER. The waste water of the community. It may be a combination of the liquid and water-carried wastes from residences, commercial buildings, industrial plants, and institutions, together with any ground water, surface water, and stormwater that may through natural means, not intentionally discharged, enter the system.
WASTEWATER FACILITIES. The structures, equipment, and processes required to collect, carry away, and treat domestic and industrial wastewater and dispose of the effluent.
WASTEWATER TREATMENT WORKS. The equipment and structures for treating wastewater, sometimes used as synonymous with WASTE TREATMENT PLANT, WASTEWATER TREATMENT PLANT, or WATER POLLUTION CONTROL PLANT.
WATERCOURSE. A natural or artificial channel for the passage of water, either continuously or intermittently.
