What is a high-capacity water well?
A high-capacity well is a water well capable of pumping at least 100,000 gallons of ground water per day (70 gallons per minute), regardless of how much water is actually pumped. A well with this much pumping capacity would also be classified as a significant water withdrawal facility (SWWF). SWWFs must be registered with the DNR Division of Water (at no cost), and water withdrawals from them must be reported annually.
