Whether a new home can legally get its own water here — the sub-state groundwater regime, from Iowa’s water agency.
Groundwater is actively managed here, but a small household well is generally still available.
Regulated-riparian permit system (Iowa Code 455B); household wells below 25,000 gpd are exempt. EXCEPTION: within designated Jordan-aquifer 'protected water source' areas (IAC 567-53.7) a new private well drilled into/through the Jordan aquifer needs Iowa DNR approval.
