Downpipe dischargin next to carport wall

Hi guys,

The downpipe I've marked up with yellow was blocked. Long story short, I have unblocked, I've cut it and left discharging on the top of the garden bed, so all the rainwater will be going right next to that brick wall. I understand this can be a problem as it can lead to that brick column/garage potentially settling/moving, however being Perth, the soil is quite sandy so I'm hoping the water will just go through.

Do you think I need to run water to the soakwell or can i just leave it discharging next to the brick wall?

Thanks!

You need to connect the pipe to a legal point of discharge which is supposed to take this amount of stormwater water and discharge it safely. Don’t rely on soil properties as even sandy soil may have a slight percentage of clay or fine material that may gets washed out overtime and cause movement in buildings.

Thanks so much! So i really need to run this pipe into a soakwell? Any idea of how much it costs to install a small soakwell with piping?
