This home’s Foundation was being poured when we arrived, so we were fourtunate to set the knock-out for the septic line. Typically 20″-22″ below finished floor is ideal.
The beast getting started. 8″ inch trench lines. 24 more to go.
Here we have trenched 4 zones with 5 lines each… One more to go.
All trenches are backfilled with observation pipes.
