Piping Connections & Preformed Cutout Removal

All catch basins and selected channels are equipped with preformed cutouts for piping connections and channel/catch basin connections. These connections are prepared as follows:

  1. Determine the cutout to be removed and mark with pencil.
  2. Using a 1/4" or 3/8" masonary drill bit, drill hole around the perimeter on 1/2"-3/4" centers.
  3. Remove the remaining fins using a hammer and a cold chisel. A grinder may be used to dress or enlarge the hole for proper pipe or channel insertion.
  4. Fit pipe or channel end into hole and apply a suitable sealant. If corrosive materials are to be transported in the trench, use the appropriate sealant.
