Outdoor water pipe in winter

Hello

I am currently building a small cabin and have a water supply with a temporary valve on my property. On the street there is a main valve (opened by the city) and then comes my valve with a tap.
It is a 3/4 plastic pipe.
The temperature is already around 0 degrees and I assume the city has to close the valve on the street. Otherwise there is still water in the pipe, right? Or is there a better solution, since I want to pour some concrete and need water?

Thank you.

I simply packed our building water connection heavily in stone wool. As long as the temperature doesn't stay below -10 for days, that's fine.
