NR 812.07(110)(110) “Telescoping method” means a method for setting a well screen where the well casing pipe is driven to the proposed screen setting depth and the well casing pipe is then pulled back to expose the screen. A packer is used to seal the annulus between the top of the screen and the bottom of the well casing pipe. NR 812.07(110m)(110m) “Temporary manure stack” means solid manure only, piled for no more than 120 days within any one year period. NR 812.07(110s)(110s) “Temporary outer casing” means a string of casing pipe that is driven, turned or placed from the ground surface into the surficial geological formation or formations as part of the process of constructing an upper enlarged drillhole and which is not intended to be left in place as a permanent well casing pipe. NR 812.07(111)(111) “Top of bedrock” means the top of firm rock as determined by a change in the action of the drilling machine or a change in the type and size of the drill cuttings. The presence of bedrock shall be indicated when a majority of the drill cuttings consist of either angular rock fragments, as in the case of crystalline bedrock, or rock fragments composed of individual grains or rock particles that are cemented together to form an aggregate, as opposed to single sediment particles, such as in sand. NR 812.07(111m)(111m) “Treatment pond” means a structure that is used for the treatment or storage of liquid waste. Treatment pond includes absorption, retention, storage and treatment ponds or lagoons. NR 812.07(112g)(112g) “Unconsolidated formation” means geological materials composed of clay, silt, sand, gravel, or cobbles that are not bedrock, and includes alluvium, glacial drift, glacial outwash, glacial till, lacustrine deposits, loess, and saprolite. NR 812.07(112k)(112k) “Upper enlarged drillhole” means a drillhole larger in diameter than the well casing pipe. NR 812.07(112m)(112m) “Upstream” means, with respect to the pump installation discharge and pressure system, in a direction back towards the well. NR 812.07 NoteNote: In previous versions of this rule the term “prior to” was used in lieu of the term “upstream.”
NR 812.07(112p)(112p) “Valve pit” means a pit that contains only piping and valves. Valve pits do not contain pressure tanks. NR 812.07(112q)(112q) “Variance” means a department approval to construct or install a water system or a portion of a water system in a manner not in strict compliance with the requirements of this chapter. NR 812.07(112v)(112v) “Vegetated treatment area,” formerly known as “filter strip,” means a component of an agricultural waste management system that is an area or strip of herbaceous vegetation designed and constructed to Natural Resources Conservation Service (NRCS) Standard 635 specifications, located adjacent to an animal barn, animal barn pen, animal shelter, animal yard or a manure storage facility and which is intended to improve water quality by reducing pollutants associated with animal manure and other agricultural wastewater runoff. NR 812.07(114)(114) “Walkout basement” means a basement with the floor at ground grade level on at least one side of the structure. NR 812.07(115)(115) “Wastewater” means any water carrying wastes created in and conducted away from residences, industrial establishments and public buildings with ground or surface water which may be present including any liquid wastes except clear water wastes. NR 812.07 NoteNote: Section NR 114.52 (22) defines “wastewater treatment plant” as a facility that provides for the treatment of sanitary or industrial wastewater or both. NR 812.07(116m)(116m) “Wastewater treatment plant well” means a well serving a wastewater treatment plant. NR 812.07(117)(117) “Water supply” means the sources, wells, pumps and intake and storage structures from which water is supplied for any purpose. NR 812.07(118)(118) “Water system” means the water supply, storage, treatment facilities and all structures and piping by which water is provided for any purpose. NR 812.07 NoteNote: Section 281.34 (1) (h), Stats., defines “well” as any drillhole or other excavation or opening deeper than it is wide that extends more than 10 feet below the ground surface and is constructed for the purpose of obtaining groundwater. NR 812.07(119g)(119g) “Well and pressure system” means the water supply and pump installation upstream of a building control valve or pressure tank and including any pressure tank.
