NJ Dept of Community Affairs — Uniform Construction Code ↗Septic (individual subsurface sewage disposal) work requires approval from the Middlesex County Environmental Health Division under state standards N.J.A.C. 7:9A.
Middlesex County NJ — Septic System Program ↗Under the NJ UCC a property owner may act as their own agent and obtain construction permits for their own building, though the permit itself is still required.

Whether a new home can legally get its own water here — the sub-state groundwater regime, from New Jersey’s water agency.
This basin is under active state management — new water use is scrutinized, though a domestic well is usually still allowed.
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 ↗Designated 1985; purveyors pumping >=100,000 gpd from the Englishtown, Wenonah-Mount Laurel and upper/middle Potomac-Raritan-Magothy aquifers were ordered to cut withdrawals to <=50% of 1983 rates. Domestic wells (<100,000 gpd) are exempt.
