"Storm building drain" means horizontal piping which conveys storm water wastes, clear water wastes or other similar water from roofs, area ways, courtyards, canopies, enclosed parking areas and other sources within or under any building or structure, installed below the lowest fixture or the lowest floor level, from which fixtures or sources can drain by gravity to the building sewer.
"Storm building sewer" means that part of the building sewer which conveys storm water waste or clear wastes, or both, discharge from storm building drains, parking lots, yard fountains or other similar sources, is not located within or under a building and which discharges to a storm collector sewer, private interceptor main sewer, private sewage system or other point of disposal.

Well, reservoir and spring location. NR 812.08(1)(1)
Any potable or nonpotable well or reservoir shall be located:
So the well and its surroundings can be kept in a sanitary condition.
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 and not downslope from a contamination source on the property or on an adjacent property regardless of what was installed first, the well or the contamination source. When a contamination source is installed upslope from a well in violation of this section after the well construction has been completed, the violation is not the responsibility of the well driller, except if the well driller knew or should have known of the proposed upslope installation of the contamination source. When there is no location on the property where this requirement can be met, a well may be constructed without a variance if it is constructed with a minimum of 20 or more feet of well casing pipe than is required by ss. NR 812.12
and Tables I and II or with a minimum of 60 feet of well casing pipe provided that the minimum well casing pipe depth requirements of s. NR 812.12
and Table I or II are met. This exception does not apply to high capacity, school or wastewater treatment plant wells. A well or reservoir is located downslope from a contamination source, regardless of the presence or absence of a structure between the well and the contamination source, if:
The ground surface elevation at the well or reservoir is lower than the elevation at the contamination source, and
Surface water that washes over the contamination source would travel within eight feet of the well or reservoir, or over the well or reservoir.
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
Section PSC 114.234
C8 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.
Such that any potential contaminant source, not identified in this section or in Table A, is a minimum of 8 feet from the well or reservoir.
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.
(2) Relation to buildings.
In relation to buildings, the location of any potable or nonpotable well shall be as follows:
When a well is located outside and adjacent to a building, it shall be located so that the center line of the well extended vertically will clear any projection from the building by not less than 2 feet and so that the top of the well casing pipe extends at least 12 inches above the final established ground grade.
When a structure is built over a drilled well, it shall have an access hatch or removable hatch, or provide other access to allow for pulling of the pump. The well casing pipe shall extend at least 12 inches above the floor and be sealed watertight at the point where it extends through the floor.
No well may be located, nor a building constructed, such that the well casing pipe will terminate in or extend through the basement of any building or terminate under the floor of a building having no basement. The top of a well casing pipe may terminate in a walkout basement meeting the criteria of s. NR 812.42 (9) (b) 1.
A well may not terminate in or extend through a crawl space having a below ground grade depression or excavation.
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.
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.
A well may not be constructed on a floodway property that is either undeveloped or has building structures but no existing well.
The regional flood elevation may be obtained from the department.
(4) Relation to contamination sources.
Minimum separating distances between any new potable or nonpotable well, reservoir or spring and existing sources of contamination; or between new sources of contamination and existing potable or nonpotable wells, 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. Minimum separating distances are listed in Table A and are as follows:
Buried building foundation drain connected to a clear water waste drain or other subsoil drain;
Fertilizer or pesticide storage tank with a capacity of less than 1,500 gallons, but only when the well is nonpotable;
NR 812.08 Note
Note: For potable wells see par. (d) 1.

Buried building drain or building sewer having pipe not conforming to ch. SPS 384
, wastewater sump, or non-watertight clear water waste sumps;

Buried pressurized sewer pipe conveying manure provided that the pipe meets ASTM specification D-2241, with standard dimension ratio of 21 or less or pressure pipe meeting the requirements of s. NR 110.13
Buried fuel oil tanks serving single family residences, including any associated buried piping;
Vertical shaft installed below grade used for intake of air for a heating or air conditioning system; or
Buried sanitary or storm collector sewer serving 4 or fewer living units or having a diameter of 6 inches or less.
Soil absorption unit receiving less than 8,000 gallons/day, existing, abandoned or alternate, but not including a school soil absorption unit;
NR 812.08 Note
Note: For school soil absorption units see par. (e); for soil absorption units receiving more than 8,000 gallons/day see par. (f) 3.
