Hydrostatic test

[A.I.H]

I need you help
I have a 10km uner ground pipeline 36" with different altitudes along it and a mountain natural
1 _ What is the precautions to avoid air content in filling process ?
2 _ Is it right to make a vent point at highest even if the location of the point will be in the middle of the pipeline to release air content?
