I drink tap water without filtering it, but I don't think there are issues concerning the filter system in our area. Some people boil their water, and while the taste is changed, I think it's as effective as filtering the water.

I don't really like the taste of bottled water unless it's flavored , so I don't drink it that much. However, I think that putting a ban on bottled water is a bad idea, since it's hard to stop using bottled water completely. If they are serious about this ban, they should increase the number of water fountains. Still, some people don't find that very hygienic. I doubt that many students would be willing to respect this ban.

Instead of the ban, they should put more effort into informing people about bottled water and its disadvantages. That way, people will try to cut down on bottled water without being annoyed.

If all that fails, increasing the price drastically might work.
