  • What are the dimensions for a slit hole? Can you post an image?

    The gap at the bottom of the drain end’s retaining wall could 4 to 10 mm high BUT only a knife cut (edge to edge) is needed in the liner itself. Place strip of shade cloth, non-metal screen and/or small amount of pea gravel covering the slit on the inside to help retain sand.

    I have now updated that chapter 14.1 with pictures, and also added
    – chapter 14.1.1 Slit Drain Instructions,
    – chapter 14.1.2 Additional Tips for long Biofilters, and,
    – chapter 14.1.3 Drainage Options.

    Thank you for bringing this to our attention, if you need more details (or have other questions) please let us know.
