Whether a new home can legally get its own water here — the sub-state groundwater regime, from Illinois’s water agency.
The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.
Reasonable-use rule (Water Use Act of 1983, 525 ILCS 45). New high-capacity wells get 30-day SWCD/ISWS review, but domestic/household wells are below the threshold and exempt (Illinois Water Well Construction Code still applies).
Limit: household wells exempt; only high-capacity points (>=100,000 gpd) notify SWCD/ISWS
Illinois Water Use Act of 1983 (525 ILCS 45) ↗Illinois State Water Survey documents unsustainable drawdown (300-800+ ft) of the deep sandstone aquifer; St. Peter sandstone is partially desaturated in Will, Kane and Kendall and some deep wells are projected to fail by ~2030, steering communities toward Lake Michigan water. The stress affects deep high-capacity municipal/industrial wells; shallow domestic wells are exempt.
