What is your favourite brand of water? For me, I love Evian or Highland. Some brands like volvic don't taste very nice, however they have nice flavoured water.
We have good city water so I drink a lot of tap water. I also try and be conscious of the environment so I try very hard not to buy bottled water. I have a metal water bottle I fill with water. The only time I buy bottled water is when I'm camping or something.
I never drink tap water anymore. Even for some cooking where it is really reliant on water I use water bottles. I have lived in cities where the tap water is bad So it's mostly a habit.
I love Dasani water - but we usually buy Ozarka. Dasani has a crisp taste though that I like to drink! 😀
I have reusable filter bottle that I fill up and bring with me plus my tap water is good, so I don't drink much bottled water at all. For me the ecological impacts it causes are too much. I drink tap water when I travel, even if it's not the best by using a SteriPen.
When I do have to buy water it's normally Voss or Fiji as I find they have a better taste and price in the long run. I have 1-2 cases of bottled water on hand in case of emergencies stored in my house, car, and at work. You'll never know when you'll need them or they'll come in handy.
