High capacity well application and instructions
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.
- Program guidance [PDF] has been developed to help department staff, well drillers and property owners understand and apply consistent requirements under 2015 Wisconsin Act 177 [exit DNR] as it relates to the definition of residential and fire protection wells.
