Trench drainfield recovery: Terralift

This system was approximately 15 years old and had a clogged drain field.  The water was backed up into the home.  The tank and distribution box have not been cleaned regularly.   The owner wanted to extend the life of his system until city sewer was available in the near future.


  • The tank and distribution box were opened and cleaned.
  • The drainfield was fractured and rejuvenated using a Terralift to blast high pressure air and polystyrene beads into the ground.
  • Bacteria supplements were added to help restore function to the drainfield.
  • The drainage was restored and the system has operated properly for five years.
