Right. You can put almost any (relatively clear) water in a clear plastic
bottle, put the bottle in the sun for a few hours, and, presto, sterilized
water.

Hmmm,
Plastic bottle? I wouldn't. I'd with glass bottle.

The glass used for making bottles also blocks UVC and even most UVB.

Then again, I have doubt about sterilizing water with a light source
that does not exterminate plankton in shallow ponds.
