High capacity wells

A high capacity well is a well that has the capacity to withdraw more than 100,000 gallons per day, or a well that, together with all other wells on the same property, has a capacity of more than 100,000 gallons per day. Residential wells and fire protection wells are excluded from the definition of a high capacity well, and their pumping capacities are not included in the calculation of a property's well capacity.

In accordance with Sections NR 812.09(4)(a) & (b), Wis. Adm. Code [exit DNR], prior department approval is necessary for the construction or operation of a high capacity well system, school well or wastewater treatment plant well.
