pistoriousp didn't really answer. Aluminum cans don't scale well to over 500ml (have you seen a 1.5lt bottle made of aluminum?), and even at 500ml they require pressurization to hold. Tetrapac is still plastic inside, but a lot more expensive, with lower lifespan and robustness and with much higher carbon footprint. It's probably a bit less vulnerable to plasticizer leaching but that's the only thing it can offer. As for glass, I'm sorry, but this is the stupidest thing I've heard all week. You obviously don't understand anything about this issue if you propose to use glass for bottled water.
