A Pozo Negro is a bore hole which is the soak-away for the overflow of a septic tank.

The hole is lined for the first 4 meters with a steal tube with an inner PVC tube that goes the the bottom of the bore hole. The overflow wast pipe of the septic tank is connected directly to this inner PVC tube as are the patio and garden drainage pipes.
