Drain heat pump condensate in case of poor soil

Hello everyone

I have built a single-family house with an air-water heat pump. The heat exchanger is a wall unit.
The house was built on a pile foundation because the soil was not load-bearing enough. Additionally, it is very clayey and therefore poorly absorbent when it comes to water.
Now I am considering how to drain the condensate water under these conditions.
Unfortunately, on this corner of the house, or rather this side of the house, there is no rainwater downpipe to which I could connect.
So at the moment, I tend to create a soakaway pit made of gravel despite the poor soil. The condensate water in the first six months was also not so much that I would be afraid the water volumes would wash my house away.

Can anyone of you say something from experience or knowledge about this problem situation?

Regards
Enrico

Yes, we have the same. Clay soil and heat pump with drainage group. I see no problem at all if done properly. You can do it!

What does "when executed correctly" mean? How is your pit dimensioned?

above all, it must be deep enough below the frost line. The infiltration group is approximately 1mx2m.
