ᐅ Allowing Rainwater to Infiltrate the Ground – The Most Cost-Effective Option?

Hello everyone,
I need to get rid of my rainwater.
Discharging into the sewer system is not allowed in our community.
At first, I wanted to install a flat tank with a pump and be done with it.
Now my neighbor told me about a well, which is possible here and is now being implemented cost-effectively.
I no longer need the rainwater, but I have already connected 100mm (4 inches) KG pipes to my downspouts and laid them out over about 16m (52 feet). The attached sketch basically shows my current installation.
My problem is this: Various forums and my execution drawing say the infiltration basin should be about 30cm (12 inches) deep. However, my pipe end is at a depth of 1m (3.3 feet).
I didn’t want to skimp on the slope to ensure no water stands, and frost protection should also be considered.
The question is: What (more cost-effective) alternatives do I have with my pipe end at 1m (3.3 feet) depth?
The groundwater level here is very high during the relevant months. Our house connections could only be installed with a 2-month delay in January using a pump to remove the water.
Thanks in advance!

Thank you for your answers.
Our home builder planned an infiltration basin measuring 5 x 2 x 0.3 meters (16.4 x 6.6 x 1 foot) approximately.
So the plan is almost like in my sketch, with the difference that two pipes should be connected to the infiltration basin (I used a Y-connector). I have now dug up the pipe a bit more, so I’m only about 50 cm (20 inches) deep. The slope test was also successful. So everything is fine.
However, I have one more question:
I bought a bit too much drainage fleece (the rest of the roll was offered to me at a discount). Is it okay if I also place fleece under the gravel? Putting it over the gravel is clear, but underneath? Maybe it’s not necessary, but could it cause any harm?
Oh, and regarding the well: the whole neighborhood has one, so I assume the water can be used at least for garden irrigation (of course, it shouldn’t be used for drinking, and the strawberries don’t need to be watered with it).
