File:SWTT High Perm Soil Cells Final.png|thumb|right|450px|'''Tree trench with soil cells on high permeability subsoil''' - This tree trench configuration possess high permeability soil ([[Soil groups]] A or B), and as a result possesses a stand pipe/clean-out for the underdrain, which is placed higher in the feature as water will infiltrate through the system much quicker. This allows for further infiltration into the system into the underlying native soil below. Once water has percolated through the soil to the perforated underdrain it is then transported out of the feature and back into the storm sewer system. This configuration also includes a monitoring well to monitor water level in the feature below the aggregate line at the bottom of the feature. It also contains soil cells similar to the low permeability configuration. <span style="color:red">'''''Note''': The following is an "image map", feel free to explore the image with your cursor and click on highlighted labels that appear to take you to corresponding pages on the Wiki.''</span>

File:SWTT Struct Soil Med High Perm Final.png|thumb|center|450px|'''Tree Trench with structural soil medium on high permeability subsoil''' - This tree trench configuration possess high permeability soil, similar to the configuration, first on the left, but instead of soil cells this tree trench contains a structural soil medium. Once water has percolated through the soil to the perforated underdrain it is then transported out of the feature and back into the storm sewer system. This configuration also includes a monitoring well below the aggregate line at the bottom of the feature. <span style="color:red">'''''Note''': The following is an "image map", feel free to explore the image with your cursor and click on highlighted labels that appear to take you to corresponding pages on the Wiki.''</span>
