Unless the context specifically indicates otherwise, the meanings of terms used in this chapter shall be as follows:
APPROVING AUTHORITYThe Monona Common Council or its duly authorized committee, agent or representative.
CARBONACEOUS BIOCHEMICAL OXYGEN DEMAND (CBOD)The quantity of oxygen used in the biochemical degradation of organic material in five days at 20° C. when the oxidation of reduced forms of nitrogen is prevented by the addition of an inhibitor. This analytical procedure shall be performed in accordance with Standard Methods.
BUILDING DRAINThat part of the lowest horizontal piping of a drainage system which receives the discharge from soil, waste and other drainage pipes inside the walls of the building and conveys it to the building sewer.
BUILDING SEWERThe extension from the public sewer or other place of disposal beginning outside the inner face of the building wall.
COMPATIBLE POLLUTANTSBiochemical oxygen demand, suspended solids, plus additional pollutants identified in the WPDES permit for the Madison Metropolitan Sewerage District Treatment Plant receiving the pollutant, if such works were designed to treat such additional pollutants to a substantial degree.
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. Wastewater or septage shall be considered free of floatable fat if it is properly pretreated and the wastewater does not interfere with the collection or 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 particles will be no greater than 1/2 inch in any dimension and will be carried freely in suspension under normal flow conditions in sewers.
INCOMPATIBLE POLLUTANTS OR WASTEWATERWastewater or septage with pollutants 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 WASTEThe wastewater from an industrial process, trade or business, as distinct from sanitary sewage, including cooling water and the discharge from sewage pretreatment facilities.
MMSD ORDINANCEThe Sewer Use Ordinance of the Madison Metropolitan Sewerage District adopted in September 1984, and any amendments thereto, and incorporated herein by reference.
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.
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.
pHThe logarithm of the reciprocal of 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 seven and a hydrogen ion concentration of 10.
PUBLIC SEWERAny sewer provided by or subject to the jurisdiction of the City of Monona.
SANITARY SEWAGEA combination of liquid and water-carried wastes discharged from toilets and/or sanitary plumbing facilities, together with such groundwater, surface water and stormwater as may have inadvertently entered the sewerage system.
SANITARY SEWERA sewer that carries liquid and water-carried wastes from residences, commercial buildings, industrial plants, and institutions, together with small quantities of groundwater, stormwater and surface water that are not admitted intentionally.
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 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 costs, of said facilities.
SEWER SYSTEMThe public sanitary sewers within a sewerage system. 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 "sewer 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 City.
SLUG LOADAny substance release at a discharge rate and/or concentration which cause interference to wastewater treatment processes or plugging or surcharging of the sewer system.
STANDARD METHODSStandard Methods for the Examination of Water and Wastewater, promulgated by the American Public Health Association, American Water Works Association and Water Environment Federation, the analytical procedures performed in accordance with 40 CFR 136, or as the United States Environmental Protection Agency otherwise determines.
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 is removable by laboratory filtering as prescribed in Standard Methods and is referred to as "nonfilterable residue."
TOTAL PHOSPHORUS (TP)The quantity of total phosphorus as determined in accordance with the 40 CFR Part 136 or as the EPA otherwise determines.
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 as synonymous with "waste treatment."
WATERCOURSEA natural or artificial channel for the passage of water, either continuously or intermittently.
