It doesn't really matter how much water you put in it. At least they have some. Like my hedgehog needs a refill everyday. So just make it suitable for your hedgehog. Try to use drinking water that you drink. Well water or anything like that isn't the best to use.
Hedgehogs can survive several days if not weeks without water, especially in the wild. But it also depends on the health and age of the hedgie. Although they can survive for days-weeks, if you have a pet hedgie, give it fresh water, best from a water dish or bowl, once or twice a day, and feed them appropriately as well.
they survive for 12 hours
This can vary largely, depending on how much your hedgehog eats and what kind of food you're buying. The food you should be buying your hedgehog will certainly be more expensive. Do not feed your hedgehog foods with processed items, such as meal. Go for organic, all natural, and hollistic foods. Every hedgehog is individual, and they will eat 1-2 tablespoons a night. Some hedgehogs need more, some need less - depending on how they keep weight on and how active they are.

He hates water because he cannot swim.
While many desert animals can live on the water contained in their food, it is reported that the Desert Hedgehog prefers to live in an oasis or coastal area. So it would seem that it enjoys having drinking water available.
If it weren't for his shoes, he'd be slower than Sonic.
