Whether a new home can legally get its own water here — the sub-state groundwater regime, from Wisconsin’s water agency.
This basin is under active state management — new water use is scrutinized, though a domestic well is usually still allowed.
Reasonable-use rule with a DNR high-capacity-well overlay (Wis. Stat. 281.34). Residential wells are statutorily excluded from the 'high capacity well' definition, so a household well needs no DNR withdrawal approval (NR 812 construction code still applies).
Limit: household wells exempt; only 'high capacity' wells (>100,000 gpd) need DNR approval
Wisconsin DNR — High Capacity Wells ↗Sand-plain region with 3,000+ high-capacity irrigation wells whose pumping draws down lakes, trout streams and wetlands (Central Sands Lakes Study). New high-capacity (>100,000 gpd) wells get case-by-case DNR review; domestic/household wells remain exempt.
