Stainless Steel

Would it be smart not to sell plastic water bottles at all? How cool would it be if the only way you could buy water is if it was sold in a stainless steel bottle. You buy your bottle at the store and fill it there as well. If  on every corner there was a filling station. At these stations you can fill your bottle with fresh cold water from stainless steel pipes. At the station there would be 5 pumps where you can fill up, you could also adjust the temperature to what you want the water to be. Each bottle would be the same size and shape. This would be expansive to start up but it would make a difference. It would cut down on pollution and would use water more effectively.
