Sachet of water? I think we have something that we call, ice water. It is a water that should be sold as Ice, but there is still water inside it, or the water is not that hard, so it will be a cold water in a plastic. The plastic is clean. During summer in our country, everyone is buying ice water and ice. I also patronize this. When there are no electricity, in order to buy cold water you need to buy ice water. There is also bottled water, I am not sure if we have water in the sachet. I think maybe in some groceries there will be something like that, but I haven't seen it in my place. Locals are using ice water even in making juices that they sell in the street. It helps others who are in street and wants some refreshment. It is quite a success selling that.
