refillable water bottles are how it's done in most of the world.
You go to a water shop, hand over a bottle, and they give you a one filled with a 15 liters of water, and you'll probably pay around 5 USD cents for that. The water will be filtered (but probably not with reverse osmosis, so there might still be a few viruses and a little lead contamination in it).
The bottles will be filled thousands of times in their lifespan. The cost is higher per liter than piped water, but per person per year it's lower, due to the fact these people perhaps use only 5 liters per day of bottled water, and do clothes washing in non-potable rainwater off their roof.
Hell, I do this for my drinking water in the United States. My tap water is perfectly safe to drink, but even after running through a brita filter it tastes aweful, so it's worth the 30 minutes a month it takes to got get RO filtered water from the water store.
