There is a special orange pvc pipe that you buy by the foot for natural gas.
It uses metal connectors on the ends.  Gas companies use it.  I used black
pipe on the ends and coated them with tar on the parts near the  ground.  I
had put pvc white drainage pipe in floor etc to make my hole.  Water line
can be run with continuous black pvc pipe.

I have phone, water, gas, and electric lines running underground from house
to garage.

Please check out with experts and code personnel in your area.
