Good looking cup. I would advise against drinking from rivers and streams. If an animal dies/defecates upstream and you drink that water, your not in for a fun hike. Violent bloody stools in between blackouts is 100% hellish. Get a nice UV water purifier pen if you want to keep drinking from streams.
Or you could just spend $15 on MSR Sweet Water Purifier Solution.
Or $40 on a SteriPen, if you don't want to mess up the flavor.
If you're not worried about viruses, this is a better option. If you are worried about viruses I'd get a Steripen in addition to that. With some iodine, bleach or aquamira as a backup for course.
I'm pretty sure it only disinfects because it gets heated up. Sadly, that's only UV-C radiation that does that, and that is filtered out almost 100% by the atmosphere. UV-A and UV-B doesn't really do this. You CAN however buy a steripen for clear water

If you really want to go techy, you could rig a hand crank flash light to double as a AA battery charger and have virtually unlimited purifications, but then it's getting overly complicated and you might as well have just used the iodine.
EDIT: I just looked it up, turns out UV-A IS in fact enough to do disrupt the DNA structure of pathogens.
