Mound drainfield recovery: Terralift & Microbubble aeration
This system alarmed often and the owner had to pump the tank frequently. The mound rockbed was clogged due to a heavy biomat. The lot has insufficient space for a replacement system. The owner wanted to recover their drainfield without excavating the landscaped yard.
- The drainfield was fractured and rejuvenated using a Terralift to blast high pressure air and polystyrene beads into the ground.
- A Microbubble aerator was added to the septic tank to prevent the biomat from reforming and clogging the system again.
- The dose pump floats were adjusted to pump smaller volumes of effluent to the mound.
- A cycle counter was added to the pump to monitor water use.
