Where I live, we get our water from a well, and I'd rather not drink it all the time. It just doesn't taste clean :c
You could always buy one of those things that you hook up to your faucet that filters the water. I dunno if it does anything for the taste, but it'll make the water nice and clean. And I've known a lot of this stuff for a while, I've switched to using one of those metal bottles. I just fill it at the tap and keep it in the refrigerator. I encourage everyone I know to do the same, it's cheaper than constantly buying a plastic water bottle. Plus they come in fun designs.
