[Star Wars] Why is the garbage compacter full of water?

You can't squish water smaller, why is it there?

A certain amount of waste fluids end up in the disposal units just under normal operation.  Half full drink containers, equipment that wasn't properly drained before disposing, that sort of thing.  It's not an intentional feature, it's just something that ends up happening.  

It doesn't really complicate or hinder the disposal process, so there's no reason to keep it from happening.
