Can you take the water reservoir out of a camelbak backpack and just use it

[Julieeeee]

as a normal backpack? i have never gone intense hiking or anything, and do not intend to use my camelbak backpack for any such activities, i am just going to use it for school and everyday carrying of objects, but my question is is whether or not you can just take out the water bladder part, so it is like a normal backpack. i found a camelbak that i really like the looks of and want to buy, so that is why i am asking.
