Best Water Pipe Type for Allotment Garden Gazebo: PEX/AL/PEX vs PE, 25cm Depth, 15m Distance

What kind of pipe to use for water connection on the plot. (Gazebo in the allotment garden) Whether to use a pex / al / pex or pe pipe. He plans to bury the pipe at a depth of approx. 25 cm and for a distance of approx. 15 m. The water will be drained for the winter.
I am asking for advice.

PE, pex for the garden is not suitable, it is just too thin.

Blue for connection.

At my parents' allotment gardens, a water installation was made with the use of PE pipes. Everything, both reception and power supply. These are numerous allotment gardens, so the main pipe is probably 4 "connections with fi25 pipes. Everything with twisted joints (I would prefer welded). Everything is powered from the municipal network (0.6MPa) works all year round. Most importantly, everything is buried below freezing of the ground, about 1.2m. Shut-off valves and meters also in the ground, in insulated manholes. Everything works as it should. So I would not disqualify PE pipes. He would rather think about burying them at least 0.8 m, because you will forget once, or you will be late to empty the pipe and the whole thing to be replaced.

And who disqualifies them?

PE pipe 25 mm or 32 mm blue + pipe insulation and appropriate depth, not 25cm from 80 cm as you suggest, as my friend above suggests + valves for draining the water, I have it done and buried myself [PE 25mm] and for the winter I drain the water from this pipe that supplies the plot.

The meter comes with 1/2 '' steel pipes, so I will use PE 20. As for the depth of burying the pipes, it does not deny that it is so deep that it is bad, BUT to dig 15 m by hand to a depth of 25 cm, and 80 cm workload it is very big.
In the fall, the water is turned off to the depth of valves, and allotment counters unscrew.
He also plans to blow compressed air from the compressor to blow out the remaining water from the pipes.

Now you're kidding, it's 3 hours of honest work.

andrefff I thought you would disqualify both Pe and PEX. That's just how I interpreted your opinion. So I misinterpreted what I am sorry for.

You have a few hours of digging 15m at a depth of 80cm, that's a laugh in the hall He always goes to hire a digger to do the job. However, as for removing the residual water for the winter, I recommend doing it with compressed air from the compressor, then it is certain that it will not defrost something.

As for the excavator, as I wrote above, it is an allotment garden. Take a small cart or a helicopter to the site.
I can see that everyone but me is suitable for digging with a shovel.
I was already digging there a bit (CLAY, ANY OLD ROUGH) pure pleasure.
I invite you to the weekend, let someone dig two meters (MIND A FEW HOURS), I will dig the rest with two left hands.

Nobody is a prophet and knows what soil you have on your ranch with clay, rubble, etc. But slowly it always goes to scratch only not nervously and it will do itself one day slowly. Dig wider and then narrow slightly 25cm then you have the so-called shovel punch

Will use a PE pipe fi 20, price approx. PLN 1.50 per meter.
Thank you for your help.
