I live in a country where tap water is not drinkable and most bottled water brands taste bad (including the more expensive ones like Nestle). I use a water delivery service a little similar to this, I paid a deposit of about $20 for three 19L bottles and every refill costs about $2.32
Pros:
- I don't have a car so getting water delivered to my front door is great, I just have to remember to put an empty bottle and a coupon outside on delivery days.
- This water has no taste, which is exactly what I expect from water
- It's cheaper than any bottled water option I have here
- Bottles are cleaned and re-used a significant amount of times so I waste less plastic
Cons:
- It's more expensive than tap, but again it's not an option for me
I also considered buying a filtering system but from what I read the initial investment and maintenance of a good one is not really worth it. I used to drink tap water back in Europe and it saddens me to have to pay so much to get decent drinking water since moving to Asia
