Sewer Line Replacement Permits in Somerset County, New Jersey

Because of the sanitary and environmental risks involved, local building departments strictly require permits and inspections before any trench can be backfilled.

With a population of around 349,846 residents, Somerset County generally runs a more streamlined permitting process than major urban hubs.
