I was going on the first half of your statement "buying bottled water or refillable purified tap water".
The latter half is still a lot more expensive than municipal water. Do you also use that water for cooking? Washing your vegetables? Washing the dishes? Bathing? Brushing your teeth?
In Flint the government recommendation (if you can believe them) is to use filtered water for the first two, which means you'll need to fetch a lot of water for pasta night.
If you have kids, "Michigan’s top poison control doctor said parents should take care to limit the time children are in the bath and be sure they don’t drink any of the water" http://www.detroitnews.com/story/news/politics/2016/01/11/do... , and they shouldn't use the water to brush their teeth.

That's even more RO water to fetch.
