A-382.20 (2) AGENT MUNICIPALITIES. The department has designated several municipalities the authority to review and approve plumbing plans and specifications for those plumbing installations located within the boundary limits of the municipality and that require approval under s. SPS 382.20. There are also municipalities designated for stormwater infiltration review when required as per s. SPS 382.20.
Note: These listings are maintained on the department's web site under the Division of Industry Services at http://dsps.wi.gov/programs/industry-services. Also see the Plumbing Program page on the Division of Industry Services web site at http://dsps.wi.gov/Documents/Industry%20Services/Forms/Plan%20Review/Industry%20Services%20Division%20Plumbing%20Agent%20Municipalities.pdf. Both web pages are subject to change.
A-382.20 (4) WATER QUALITY MANAGEMENT AGENCIES (WQM.) There are 23 water quality management agencies serving the state. These agencies review proposed sewer extensions and provide Sewer Service Area Conformance letters (also known as WQM letters).
Note: Sewer service area planning is regulated by the department of natural resources. More information may be available at http://dnr.wi.gov/topic/Wastewater/SewerServiceArea.html.
A-382.30 (4)-1. BRANCH INTERVALS.
A-382.30 (4)-2. RECEPTOR DESIGN. The following table lists the gallons per minute (GPM) that can be expected to readily flow through a given size trap where the receptor has a height (H) as indicated.
Also listed is a drainage fixture unit (dfu) load that a given size receptor trap may be expected to adequately receive.
Note: A minimum individual 4 inch diameter trap and drain for a commercial type dishwasher is recommended.
A-382.30 (4)-3. SLOPE BETWEEN MANHOLES IN CONVENTIONAL GRAVITY SEWERS. Section NR 110.13 (2) (c) reads:
Slope. 1. Conventional gravity sewers shall be laid with uniform slope between manholes. All sewers shall be designed and constructed to give average velocities of not less than 60 centimeters per second (2.0 feet per second) when flowing full. The minimum slopes in Table 1 shall be provided. Slopes less than 0.4% may be permitted for 20 centimeter (8 inch) sewers. In such cases, however, the slope may not be less than 0.3%. The department [DNR] will approve these sewers only when the owner demonstrates that physical circumstances warrant the lesser slope. Furthermore, approval will not be granted until the department [DNR] has received written assurance from the operating authority that the authority will provide the additional maintenance which may result from the sedimentation due to decreased velocities.”

NR 812.08 Well, reservoir and spring location. (1) GENERAL. Any potable or nonpotable well or reservoir shall be located:
(a) So the well and its surroundings can be kept in a sanitary condition.
(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 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 812.13 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 or 812.13 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:
1.   The ground surface elevation at the well or reservoir is lower than the elevation at the contamination source, and
2.   Surface water that washes over the contamination source would travel within eight feet of the well or reservoir, or over the well or reservoir.
(c) As far away from any known or possible source of contamination as the general layout of the premises and the surroundings allow.
Note: Section PSC 114.234 requires that a horizontal clearance of at least ¾ 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.
(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 or reservoir.
(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.
(2) RELATION TO BUILDINGS. In relation to buildings, the location of any potable or nonpotable well shall be as follows:
(a) 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.
(b) 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.
(c) 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. to 4. A well may not terminate in or extend through a crawl space having a below ground grade depression or excavation.
(3) RELATION TO FLOODPLAINS. (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.
