Section NR 812.39 - High capacity well water level and water usage measurement(1) WELL WATER LEVEL MEASUREMENT. The department may require the installation and calibration of means for the measurement of static and pumping well water levels for any high capacity well and may require the operator of the well to submit monthly reports of this information. Installation shall be made in a manner as to prevent entrance of contaminants to the water system and in compliance with approval conditions and as depicted in Figure 3 of ch. NR 812 Appendix. (a) When an air line with altitude gauge is installed in a well, the equipment and installation shall meet the following requirements:1. When the top of the well is not housed in a pumphouse or other structure, that portion of the air line extending above the pump discharge head or well seal, and to a depth of at least 3 feet into the well, shall be metal or shall be fiber or wire-braided reinforced tubing. An "air quick-disconnect" fitting shall be installed for the top of the air line such that the altitude or pressure gauge may be easily removed and stored in a dry place when water levels are not being measured. The "air quick-disconnect" fitting shall be installed to point downward or shall be capped such that contaminants cannot enter the air line.2. A silicone rubber sealant or a watertight threaded metal fitting shall be used to seal the opening in the pump discharge head or the well seal through which the air line extends.(b) When an electrical water level sensing device, a steel tape or similar means for use in measuring water levels is used in lieu of an air line with altitude gauge, the opening in the pump discharge head or well seal used for the measurements shall be sealed watertight when water levels are not being measured.(2) RECORDING TOTAL WATER USAGE. The department may require the installation and calibration of means for the recording of total water usage from a high capacity well and shall require the operator of the well to submit monthly reports of this information.Wis.
