NR 812.27(5)(5) Disinfection and well seals. The pump installer shall disinfect any potable well and water system according to s. NR 812.41 (1) and (2) upon completion of the original pump installation and thereafter, anytime the well is entered for the purpose of measuring or diagnosing any feature or problem with the well or after the well is entered for rehabilitation, redevelopment, reconditioning or cleaning or if the well is entered for the purpose of installing, replacing or repairing any equipment located within the well. Following disinfection, the disinfectant shall be flushed according to s. NR 812.41 (2). The disinfection and flushing shall be completed before the system is placed into service. The pump installer shall seal or cover the well with a vermin–proof cap or seal approved for use under s. NR 812.091. The pump installer may designate the owner, the property lessee, or any other person to flush the system.

NR 812.27(7)(7) Notification of contaminated wells. Pump installers shall notify the well owner as soon as practicable, but no later than 48 hours, after the pump installer is informed that the water from the well contains contaminant levels in excess of the standards specified in s. NR 812.06.

NR 812.27(8)(8) Bacteria positive wells. Pump installers shall return to the well site to diagnose and attempt to correct a problem when an initial sample from a potable well is positive for coliform bacteria. Corrective action should be taken no later than 10 days after the pump installer is informed of a total coliform bacteria-positive result or prior to the well being placed into service, whichever is later. After corrective action the well shall be disinfected and flushed in accordance with s. NR 812.41 and sampled in accordance with s. NR 812.46 (1).

NR 812.27(10)(10) Noncompliance. When a pump installer has performed pump installation work not in compliance with this chapter, the pump installer shall return to bring the system into compliance. The pump installer shall pay all costs for bringing the installation into compliance with this chapter, other than those costs that would have been charged for an initially complying installation.

NR 812.27(11)(11) Open annular space. A pump installer may not install a pump in a well having an open annular space that extends deeper than twice the depth of the pitless adapter or pitless unit. When an annular space is open to a depth greater than this depth, the pump installer shall inform the well driller so that the well driller knows to return to the job site and seal the annular space according to s. NR 812.20. The pump installation shall not be completed until the well driller has resealed the annular space. If the annular space is open to a depth less than or equal to twice the depth of the pitless adapter, the pump installer may seal the open annular space with an approved granular bentonite hydrated with clear water from an uncontaminated source.

NR 812.27(12)(a)(a) When required to measure well casing pipe depth by this chapter or at the request of the department, the pump installer shall document the measurement on a form specified by the department and submit the form to the well owner and the department no later than 30 days after performing the measurement.

NR 812.28NR 812.28 Pump installation equipment and supply pipe. Pump installation products and equipment may not be used unless they are approved for use under s. NR 812.091. Pump discharge and supply piping shall conform to the requirements specified in s. NR 812.11 for steel pipe or shall conform to the requirements in the “Pipe and Tubing for water services and private water mains” table in s. SPS 384.30, except that Type M copper pipe may not be installed underground. Pipe used for year-round installations shall be protected from freezing. Lead-based solder for pipe connections may not be used. Limitations on the use of plastic pipe are found in s. SPS 384.30. Plastic pipe may not be used for buried pipe in soils known to be contaminated with volatile organic chemicals. Plastic pipe may be used as drop pipe installed within a well or for discharge piping between the well and the building served, provided it meets standards specified in s. SPS 384.30 and has a minimum pressure rating of 150 pounds per square inch. When plastic pipe extends through the seal of a well with an above-ground discharge, the portion of the plastic pipe extending above-ground from the well shall be protected from sunlight or the plastic pipe used shall be of the type with inhibitors recommended for use in direct sunlight.
