Technical Documents

Our Recommendation

  • 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.
  • 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.
