Our septic is gravity fed on a small hill. It is very basic, and we do not need multiple inspections per year. Are you sure these aren’t County required inspections? I live in Hunterdon County and never heard of it.

That said I know it depends on your land conditions and geography.

They’re referring to a level IV or V system. They’re used when the ground doesn’t perc well.

I think the inspection requirement is fairly new, and only kicks in with new systems. That being said, at this house the water table is quite high. The well serving the house is only about 90 ft deep.
