I agree that filtering (filters and UV) is the proper end of the system. What I'm confused about is the practical reasoning.
Let's say you have a jug of water that you run through a filter and UV light before using. You'll end up with a darn good cup of coffee. Now, what if you added a drop of dirt, a few dead insects a live larva, and a piece of leaf debris to that jug? After passing through a filter and UV light, you'll still have a darn good cup of coffee. But add a few things each time to the jug and you have to question what type of contamination your filters must contend with, not to mention the serviceable life span of the filters with that extra stuff in the water. I would think that the biological/vegetative mix isn't stable from the first filling to the cleaning and something biologically is going on in the water storage tank.
As for the mechanics, its a non-mechanical passive system.
