NR 812.08 NR 812.08Water well, heat exchange drillhole, reservoir and spring location.
NR 812.08(1) (1)General. Any potable or nonpotable well, reservoir, or spring shall be located:
NR 812.08(1)(a) (a) So the well and its surroundings can be kept in a sanitary condition.
NR 812.08(1)(b) (b) At the highest point on the property consistent with the general layout and surroundings if reasonably possible, but in any case protected against surface water flow and flooding.
NR 812.08(1)(c) (c) As far away from any known or possible source of contamination as the general layout of the premises and the surroundings allow.
NR 812.08 Note Note: Section PSC 114.234 (6) requires that a horizontal clearance of at least 3/4 of the vertical clearance of the conductors, including overhead power lines to the ground required by Rule 232 shall be maintained between open conductors and wells. Persons installing wells must comply with this requirement.
NR 812.08(1)(d) (d) Such that any potential contaminant source, not identified in this section or in Table A, is a minimum of 8 feet from the well, reservoir, or spring.
NR 812.08(1)(e) (e) Every well shall be located so that it is reasonably accessible with proper equipment for cleaning, treatment, repair, testing, inspection and any other maintenance that may be necessary.
NR 812.08(1)(f) (f) In a manner to meet the additional location and construction specifications of s. NR 812.12 (3), (15), (16), and (17).
NR 812.08(2) (2)Relation to buildings. In relation to buildings, the location of any potable or nonpotable well shall be as follows:
NR 812.08(2)(a) (a) When a well is located outside it shall be located so that the top of the well casing pipe extends at least 12 inches above the final established ground grade and in a manner such that it is not directly in line with a rainwater downspout outlet or other similar clear water discharge that creates a sanitary hazard to the well.
NR 812.08 Note Note: The department recommends that when a well is located adjacent to a building, it be located so the center line of the well extended vertically will clear the overhang of any building by not less than 2 feet to allow for well reconstruction and for pulling the pump.
NR 812.08(2)(b) (b) When a structure is built over a drilled well, it shall have an easily removable access hatch, or provide other practicable access to allow for pulling and servicing the pump. The well casing pipe shall extend at least 12 inches above ground grade or above the ground-grade floor of the building and shall be sealed watertight at the point where it extends through the floor.
NR 812.08(2)(c) (c) No well may be located, nor a building constructed, such that the well casing pipe will terminate in a basement or extend through the basement of any building or terminate under the floor of a building having no basement. A well may not terminate in or extend through a crawl space having a below ground grade depression or excavation.
NR 812.08 Note Note: Wells terminating in basements and below-grade crawl spaces often pose a sanitary hazard to safe drinking water so they have not been allowed to be constructed, nor have screens been allowed to be replaced since April 10, 1953. Many wells terminating in basements or crawl spaces do not meet the requirements of Subchapter IV.
NR 812.08 Note Note: This paragraph does not apply to wells located in alcoves or subsurface pumprooms adjoining a basement.
NR 812.08(2)(d) (d) The top of a well casing pipe may terminate in a walkout basement if the following conditions are met:
NR 812.08(2)(d)1. 1. It is possible to walk directly outside from the walkout basement without walking upstairs or upslope.
NR 812.08(2)(d)2. 2. The surface of the ground around the outside exit door of the walkout basement slopes down away from the door.
NR 812.08(2)(d)3. 3. The well and pump installation are accessible for repair and removal.
NR 812.08(2)(d)4. 4. The well produces water continuously free from contaminants in excess of the drinking water standards of s. NR 812.06.
NR 812.08(2)(d)5. 5. The well casing pipe depth meets the requirements of s. NR 812.42 (1) (b).
NR 812.08(2)(d)6. 6. The well and pump installation are in compliance with all other requirements of this chapter.
NR 812.08(2)(d)7. 7. The walkout basement is not subject to flooding
NR 812.08(2)(d)8. 8. The walkout basement is not in a floodway or floodplain.
NR 812.08(2)(e) (e) A well may not terminate in or extend through a crawl space having a below grade depression or excavation.
NR 812.08(2)(f) (f) If a well must be located in a driveway, parking area, walkway or other high traffic area due to lot size or to meet minimum required separation distances between the well and contaminant sources, the well may be contained within a driveway ramp structure without department approval providing the driveway ramp meets the specifications of s. NR 812.36. Driveway ramps may not be constructed or located in a floodway or floodplain.
NR 812.08(2)(g) (g) A yard hydrant may not be installed within or on a well.
NR 812.08(3) (3)Relation to floodplains.
NR 812.08(3)(a)(a) A potable or nonpotable well may be constructed, reconstructed or replaced in a floodfringe provided that the top of the well is terminated at least 2 feet above the regional flood elevation for the well site.
NR 812.08(3)(b) (b) A well may be reconstructed or replaced in a floodway provided that the top of the well is terminated at least 2 feet above the regional flood elevation for the well site.
NR 812.08(3)(c) (c) A well may not be constructed on a floodway property that is either undeveloped or has building structures but no existing well.
NR 812.08(3)(d) (d) The regional flood elevation may be obtained from the department.
NR 812.08(4) (4)Relation to contamination sources. Minimum separating distances between any new potable or nonpotable well, heat exchange drillhole, reservoir or spring and existing sources of contamination; or between new sources of contamination and potable or nonpotable wells, heat exchange drillholes, reservoirs or springs shall be maintained as described in this subsection. The minimum separating distances of this subsection do not apply to dewatering wells approved under s. NR 812.09 (4) (a). Greater separation distances may be required for wells requiring plan approval under s. NR 812.09. Separation distance requirements to possible sources of contamination will not be waived because of property lines. Separation distances shall be measured from the edge of the well, reservoir or spring, to the nearest edge of the contamination source.
