Restricted site with advanced treatment: Pine Lake Finlayson, MN

This customer had a non compliant system. The lot was oddly shaped and there was very little space after setbacks. The existing drainfield covered part of the available space left for a new one. The owner also wanted to preserve the trees on the lot.


  • A dig out was completed over part of the existing system and clean sand corrected the soil conditions.
  • A landscape block wall was constructed and a drainfield was built inside.
  • Peat filter advanced treatment was used to preserve space and lower the height of the wall.
