NR 812.42(11)(a)(a) Pits and alcoves, noncompliant casing height or well deepening. Before extending any well casing pipe out of a pit or alcove, extending casing when the height is noncompliant, or deepening a well constructed by another individual, the well driller or the pump installer shall measure the well casing pipe depth to verify that the casing depth complies with the rules in effect at the time the well casing was installed including any special well casing depth area requirements or variances, if no confirmable well construction report can be found 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(11)(am)(am) Reconstruction. A well constructed in violation of the requirements in effect at the time of construction or a well constructed to meet the requirements in effect at the time of construction but not according to the construction requirements of ss. NR 812.09 to 812.15 may not be reconstructed.

NR 812.42(11)(b)(b) Sample Faucet. When doing any pump work involving replacement of the pressure tank, or work involving the water supply piping inside the basement or building, the pump installer shall install sample faucets that meet the requirements specified in s. NR 812.34 if any are missing. The pump installer shall also replace any sample faucet that does not comply with the requirements of s. NR 812.34, including replacement of any threaded sample faucet with a sample faucet without threads. The pump installer or well owner may not file the threads off a noncomplying sample faucet.

NR 812.42(11)(c)(c) Casing Height.

NR 812.42(11)(c)1.1. When doing any water well work or pump installing work that involves entry into a well located outside a building, the water well driller or pump installer shall extend the well casing pipe to at least:

NR 812.42(11)(c)2.2. When the well casing height above grade does not comply with subd. 1. a. or b., the well driller or the pump installer shall measure the well casing pipe depth to verify that the well casing pipe depth complies with the rules in effect at the time that the well was constructed, if there is no confirmable well construction report available 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(11)(d)(d) Well cap or seal. When doing any water well work or pump installing work that involves entry into a well, the well driller or pump installer shall replace any unapproved well cap or seal with an approved well cap or sanitary well seal.

NR 812.42(11)(e)(e) Nonpressurized conduit. When any water well drilling work or pump installing work is performed involving entry into a well that has a nonpressurized conduit and the nonpressurized conduit may continue to be used, the well driller or pump installer shall evaluate the integrity of the nonpressurized conduit and its connection to the well casing pipe by performing a pressure test. The nonpressurized conduit shall be tested and proven watertight under a pressure of not less than 14 psi. The pressure shall be maintained for at least 30 minutes. If the nonpressurized conduit fails the pressure test, the installation shall be changed to a pitless connection. The nonpressurized conduit shall be completely eliminated by cutting off the well casing pipe below the nonpressurized conduit and extending the well casing pipe to at least 12 inches above grade and installing pressurized discharge piping according to the requirements of ss. NR 812.28, 812.31 and 812.32 (4). The extension of the well casing pipe shall be in accordance with sub. (12).

NR 812.42(11)(f)(f) Corrections. The features specified in pars. (a) to (e) must be corrected and may not be noted on a noncomplying features form instead of correcting the noncomplying feature or testing the nonpressurized conduit.

NR 812.42(12)(a)(a) The well casing pipe in the ground may only be extended up if it has the minimum wall thickness for its diameter according to the requirements of s. NR 812.11 (6) Table B and is not in a deteriorated condition. If it does not meet these requirements, the well shall be filled and sealed according to the requirements of s. NR 812.26. The well casing pipe extension (riser pipe) shall meet the requirements of s. NR 812.11 (6) and shall be attached to the top of the existing casing by any of the following methods:

NR 812.42(12)(a)1.1. Cutting off the well casing pipe in the ground squarely, providing a bevel for the top of the well casing pipe and making a watertight weld between the beveled end of the well casing pipe and the beveled end of the riser pipe.

NR 812.42(12)(a)2.2. Cutting threads on the top of the well casing pipe and the bottom of the riser pipe with a pipe die and using a full-standard recessed threaded coupling to provide a watertight connection between the two pipes.

NR 812.42(12)(a)3.3. Welding a properly-sized, snug-fitting, pipe nipple, beveled on the lower end and having threads on the upper end, and meeting the requirements of s. NR 812.11 (6) to the beveled end of the well casing pipe. The pipe nipple shall be welded on the inside and the outside contact surfaces of the pipe nipple. A threaded riser pipe shall be screwed onto the top of the welded on pipe nipple.

NR 812.42(12)(a)4.4. Reaming out the threads of a full standard recessed coupling, at least 1/3 the length of the coupling, and welding the coupling to the top of the cut-off well casing pipe with a fillet weld on the inside and outside contact surfaces of the coupling. The riser pipe shall be threaded into the top of the coupling.
