When you put your puppy in a crate and leave for work for the day you should leave the puppy a little bit of water so they don't get dehydrated.
Just don't leave too much water out for the puppy so they do not have to pee so much however it's better to have the puppy pee in the crate than to let the puppy get too thirsty.
You could put a puppy training pad in the crate to make it easy to cleanup the pee that the puppy may do when you are away from the house and the puppy is in the crate.
When I had a puppy I would put a puppy training pad in the crate and then leave the puppy a small bowl of water so that it didn't get too thirsty which was good enough for the puppy.
The puppy peed some in the crate on the puppy training pad but it wasn't too bad and was easy to cleanup.
