Have smallish 650 sq. ft. cottage in Northern Michigan - seasonal for non-winter months.
Replumbing entire DWV system, and need to know what depth to exit cottage for future new septic system (elevated-engineered system) connection.
Have heard conflicting stories, e.g. top of (3" sch. 40 pipe in my case) at least 8" below ground level.
Please advise. After exiting, will travel short distance to dousing tank - grinder pump then some 300' to field.
