Percolation Catch Basin

Collecting surface runoff and replenishing groundwater

  • Catch basin with smooth inner and outer walls on the upper part, with lower part with perforated ringed outer wall.
  • Possibility of having the outer wall corrugated over the entire height of the catch basin for off-road application.
  • Corrugated perforated catch basins must be selected based on a non-roadway installation, whereas a catch basin with a perforated smooth exterior wall can be installed in either roadway or non-roadway applications.
  • The risk of heaving due to the freeze-thaw cycle must be taken into account. Soil movement will not affect a catch basin with smooth exterior wall.
  • Withstands CL-625, H-25 and HS-25 loads.
  • The percolation catch basin allows a deep percolation.

Our Recommendation

  • Precautions must be taken and the flows must be calculated to ensure that water returned to the soil does not weaken surrounding structures.
  • The perforation plan can be designed based on the percolation properties of the in situ soil.
