NR 812.42(6)(c)(c) School and high capacity wells. Pump installations for water supplies serving schools, and high capacity wells shall be provided with an above-ground discharge meeting the minimum requirements of s. NR 812.32.

NR 812.42(6)(d)(d) Pit pump location. A pump located in a conforming pit or alcove shall be installed to allow the sealing of the top of the well with an approved one-piece sanitary well seal.

NR 812.42(6)(e)(e) Hand pumps. Hand pumps may be continued in service if the pump base flange is bolted watertight to a well casing pipe flange and has a gasket seal; if the pump is firmly threaded to the well casing pipe; or if the structured base of the pump has recesses and is bolted to the top of the well casing pipe.

NR 812.42(6)(f)(f) Pump connections to reservoirs. If water is pumped to a reservoir, the piping attachment to the pump shall be made with watertight pipe fittings. The discharge pipe from the pump shall enter the reservoir in a watertight manner through that portion of the structure extending above the ground grade, unless a subsurface reservoir supply pipe is connected to the well by an approved pitless adapter and the supply pipe can be maintained under a continuous pressure head which is greater than the ground surface elevation. In such case the supply pipe shall terminate near the bottom of the reservoir. A float control switch or low and high water level electrical pump-control elements may be provided to control the pump. A check valve may be installed only in the portion of the pump discharge pipe located within the well.

NR 812.42(6)(g)(g) Pump installations for flowing wells. Pump installations for flowing wells shall meet the requirements of s. NR 812.32 (9).

NR 812.42(7)(a)(a) When a well is not terminated in a basement, in a walkout basement, in a pit, or in an alcove, the well casing pipe shall extend above grade as follows:

NR 812.42(7)(a)1.1. Low capacity wells, except school and wastewater treatment plant wells, constructed before February 1, 1991 shall terminate at least 8 inches above established ground grade,

NR 812.42(7)(b)(b) When the height of a well casing pipe does not meet the requirements of this section, it shall be extended in accordance with subs. (11) and (12) to a height at least 12 inches above ground grade or above the floor of a pumphouse; or, if applicable, 2 feet above the regional flood elevation.

NR 812.42(7)(c)1.1. When a well is terminated in a basement, a below-grade crawl space, in a walkout basement, in a pit or in an alcove, the well casing pipe shall extend 6 inches above the floor of the structure.

NR 812.42(7)(c)2.2. When the height of a well casing pipe does not meet the requirements of this section, it shall be extended in accordance with sub. (12) to a height at least 12 inches above the floor of the structure, except that for wells extended out of pits and alcoves the well casing pipe shall be extended at least 12 inches above the outside ground grade. When the well would create an obstruction to pedestrian passage, the well casing pipe may be raised to a height just below the ceiling of the alcove structure.

NR 812.42(7)(c)3.3. The well casing pipe may only be extended if the well meets the well casing pipe depth requirements of sub. (1) (b). If it does not meet the requirements of sub. (1) (b), the well shall be filled and sealed according to the requirements of s. NR 812.26. The well casing pipe depth shall be measured before extending the well casing pipe, if there is no confirmable well construction report for the well. Well details, including location, well casing pipe depth, total well depth, distances to possible contaminant sources, and well owner information shall be entered on a form and submitted to the department in accordance with s. NR 812.10 (15).

NR 812.42(8)(a)(a) A noncomplying well cap or well seal shall be replaced with an approved well cap or well seal in any of these situations:

NR 812.42(8)(c)(c) Split-plate well seals may only be used when the well is located in a pumphouse or a building.

NR 812.42(8)(d)(d) No open holes, other than an optional screened well vent, may exist in a new replacement well cap or well seal.

NR 812.42(8)(e)(e) Approved well caps or approved well seals shall be installed by licensed water well drillers or registered water well drilling businesses, or licensed pump installers or registered pump installing businesses.

NR 812.42(9)(a)(a) Wells in basements and below-grade crawl spaces, not including wells in alcoves.

NR 812.42(9)(a)1.1. Wells constructed after April 10, 1953 terminating in basements or wells constructed after July of 1951 terminating under a building addition shall be permanently filled and sealed according to the requirements of s. NR 812.26.

NR 812.42(9)(a)3.3. Screens may not be replaced on driven point wells terminating in or extending through basements or below-grade crawl spaces. When a driven point well screen needs replacement, the driven point well shall be permanently filled and sealed according to the requirements of s. NR 812.26. Any replacement well shall meet the requirements for new wells in this chapter.
