Urine safer to drink than most of earth's water. Salt water will make you more dehydrated while stagnet water can give a sever infection and kill you. This is why keeping hydrated when stranded in the ocean or lost in the wilderness is so god damn hard and that is why Bear Grylls drinks it when he needs to.

Also, drinking urine is more of a survival thing. It won't keep a person from going dehydrated but it will keep them hydrated longer. If you are SEVERLY dehidrated, don't try it. You won't produce any. You shouldn't live off of urine, as it won't serfice over clean water.
