DOMESTIC WASTEWATER; NORMAL DOMESTIC STRENGTH WASTEWATERWater-carried wastes normally discharging into the sanitary sewers from dwellings (including apartment houses and condominiums) and commercial establishments, free from stormwater and industrial waste. Domestic wastewater shall have a strength equal to or less than 250 mg/l BOD5, 250 mg/l suspended solids, and elemental phosphorus equal to or less than 12 mg/l.
EASEMENTAn acquired legal right for the specific use of property owned by another.
FLOATABLE OILOil, fat, or grease in a physical state such that it will separate by gravity from wastewater by treatment in an approved pretreatment facility. A wastewater or septage shall be considered free of floatable fat if it is properly pretreated and the wastewater does not interfere with the collection of treatment system.
GARBAGEThe residue from the preparation, cooking, and dispensing of food and from the handling, storage, and sale of food products and produce.
GROUND GARBAGEThe residue from the preparation, cooking, and dispensing of food that has been shredded to such degree that all particulates will be no greater than 1/2 inch in any dimension and will be carried freely in suspension under normal flow conditions in sewers.
HOLDING TANK SERVICE AREAThe area outside the POTW's sewer service area, but inside or equal to the POTW's planning area where a contract has been developed for holding tank wastewater to be treated at the Wastewater Treatment Facility.
INCOMPATABLE POLLUTANTS OR WASTEWATERWastewater or septage with pollutants or of such a strength that will adversely affect or disrupt the wastewater treatment processes or effluent quality or sludge quality if discharged to the sewerage system facility.
INDUSTRIAL WASTE; INDUSTRIAL WASTEWATERThe wastewater from industrial process, trade, or business, as distinct from sanitary sewage, including cooling water and the discharge from sewage pretreatment facilities.
LICENSED DISPOSERA person or business holding a valid license to do septage servicing under Ch. NR 113.
MUNICIPAL WASTEWATERThe wastewater 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 that may have inadvertently entered the sewerage system. Also termed "sewage."
NATURAL OUTLETAny outlet, including storm sewers, into a watercourse, pond, ditch, lake or other body of surface water or groundwater.
PARTS PER MILLIONA weight-to-weight ratio; the parts per million value multiplied by the factor 8.34 shall be equivalent to pounds per million gallons of water.
PERSONAny and all persons, including any individual, firm, company, municipal or private corporations, association, society, institution, enterprise, government agency, or other entity.

It shall also include sewers within or outside the corporate boundaries that serve one or more persons and ultimately discharge into the Webster sanitary sewer system, even though those sewers may not have been constructed with sewer funds.

A separate segregated district replacement fund shall be established and used only for replacement of equipment.
RESIDENTIAL EQUIVALENT UNITThe system whereby sewer user charges can be distributed amongst the different types of users on an equitable basis. The unit is use-based and is established using a neutral parameter such as gallons of water used or volume of wastewater expected from a user.
RESIDENTIAL USERAny user whose premises are used primarily as a domicile for one or more persons and discharges only domestic wastes, but not including dwellings classified as "commercial user."
SANITARY SEWAGEA combination of liquid and water-carried wastes from residences, commercial buildings, industrial plants, and institutions, together with small quantities of ground-, storm-, and surface waters that are not admitted intentionally.
SEPTAGEThe wastewater or contents of septic or holding tanks, dosing chambers, grease interceptors, seeping beds, seepage pits, seepage trenches, privies or portable restrooms.
SEWAGEThe spent water of a community. The preferred term is "municipal wastewater."
SEWERAGE SYSTEMAll structures, conduits and pipes, by which sewage is collected, treated, and disposed of, except plumbing inside and in connection with buildings served, and service pipes, from building to street main.
SEWER SERVICE AREASThe areas presently served and anticipated to be served by a municipal wastewater collection system. State regulations (Ch. NR 121) require that water quality management plans delineate sewer service areas of urban areas with a population of over 10,000. Approved facility plans contain less detailed sewer service areas for communities under 10,000 population.
SEWER SERVICE CHARGEA service charge levied on users of the wastewater collection and treatment facilities for payment of use-related capital expenses as well as the operation and maintenance costs, including replacement of said facilities.
SEWER SYSTEMThe common sanitary sewers within a sewerage system which are primarily installed to receive wastewaters directly from facilities which convey wastewater from individual structures or from private property and which include service connection y-fittings designed for connection with those facilities. The facilities which convey wastewater from individual structures, from private property to the public sanitary sewer, or its equivalent, are specifically excluded from the definition of "sewerage collection system, except that pumping units and pressurized lines for individual structures or groups of structures may be included as part of a sewer system when such units are cost effective and are owned and maintained by the sewerage owner.
SLUG LOADAny substance release at a discharge rate and/or concentration which causes interference to wastewater treatment processes or plugging or surcharging of the sewer system.
STANDARD METHODSThe examination and analytical procedures set forth in the most recent edition of "Standard Methods for the Examination of Water, Sewage, and Industrial Wastes" published jointly by the American Public Health Association, the American Water Works Association and the Water Pollution Control Federation.
STORMWATER RUNOFFThat portion of the rainfall that is collected and drained into the storm sewers.
SUSPENDED SOLIDSSolids that either float on the surface of, or are in suspension in, water, wastewater, septage, or other liquids and that are removable by laboratory filtering as prescribed in "Standard Methods" and is referred to as nonfilterable residue.
UNPOLLUTED WATERWater 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 benefited by discharge to the sanitary sewers and wastewater treatment facilities provided.
USERAny person who discharges, or causes to be discharged, domestic wastewater, industrial discharges or any other wastewater into the public sewer system.
WASTEWATER FACILITIESThe structures, equipment, and processes required to collect, carry away, store, and treat domestic and industrial waste and septage and dispose of the effluent and sludge.
WASTEWATER TREATMENT WORKSAn arrangement of devices and structures for treating wastewater, septage, industrial waste, and sludge. Sometimes used synonymously with "wastewater treatment facility(ies)" [WWTF(s)] or "Publicly Owned Treatment Works" (POTW).
