If the urine is from a healthy and hydrated person, only chemical pH and spectroscopy tests will tell the difference; without this equipment, there is no difference since urine is more than 99% water anyway (at least if the person is hydrated and healthy).
Otherwise, urine sometimes gains a yellowish-gold tint from the buildup of wastes it carries, but water can also have this buildup on its own from other sources such as rust in the piping.
