Water rights & wells in Cumberland County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from New Jersey’s water agency.

Over-appropriated / declining

The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.

Household wellExempt — no permit or water right

No allocation permit for a household well below ~70 gpm even inside the Water Supply Critical Areas; the critical-area cutbacks applied to large public purveyors, not domestic wells. A NJDEP well-construction permit is still required (50,000 gpd threshold in the Highlands Preservation Area).

Limit: < 100,000 gal/day (~70 gpm)

NJDEP — Water Allocation
  • Water Supply Critical Area 2 (Potomac-Raritan-Magothy)partial of county

    Designated 1993; PRM withdrawals capped at the 1983-1991 maximum, public-supply pumping cut ~22%, and new PRM water-supply allocations prohibited within the depleted margin. Domestic wells (<100,000 gpd) are exempt.

    NJDEP (NJ Critical Area No. 2) / USGS

Regulated-riparian state (large uses permitted). Groundwater rules change and basin boundaries follow the aquifer, not the county line — confirm current well and appropriation rules with the New Jersey state water agency before you buy or drill.Groundwater governance as of Jul 2026, cited to each administering agency.
