What you should keep out of the stormwater drain

​Waste and contaminants from industrial sites and households can pollute our waterways if not managed properly.

What gets through stormwater drains and waterways ends up at sea.

Keep these items out of your stormwater drains:

  • animal waste

  • construction materials and debris
  • farm waste
  • lawn clippings and yard waste
  • pool or spa pool water
