To my understanding, water has no nutritional value. It has nothing in it. It’s simply just water.
That said, why is it so crucial to life?

Lots and lots of substances can dissolve in water. We tend not to notice this because we deliberately make most of our stuff out of substances that don’t dissolve in water. But water can bring nutrients and remove waste products inside our bodies, and most of the stuff inside our cells float around in it, so that it can move around and perform cellular processes that are part chemistry, part machinery. The solubility of a substance can also be easily changed by attaching or removing a few atoms. Much of what the liver does is to make stuff that the body needs to get rid of more water soluble, so that the kidneys can put it in the urine. Bones are grown by taking soluble calcium and making it insoluble.
