Overview:
This system had effluent surfacing within 8 years of being constructed.  A heavy biomat build up in the drainfield caused the failure.  The drainfield rockbed was completely full of liquid.

Solution:

• The University of Minnesota was consulted to confirm soil conditions and reason for failure.
• A Microbubble aerator was installed in the septic tank.
• Surfacing was eliminated within a month.
• The liquid level in the rockbed was normal at 60 days.
