We’ve pinched and reorganized our household budgets. But we still often overpay for commercially bottled water. On an annual basis, the typical American consumer spends $1,400 on bottled water vs. 49 cents for the same amount of water from our kitchen faucet, according to the Center for a New American Dream, a nonprofit consumer group in Maryland.

Bottled water does not taste better, according to blind taste tests, and tap water must meet stricter safety measures. New American Dream has just launched a national educational campaign designed to promote filtered water from the kitchen sink.

To help you calculate how much more you may be spending for bottled water, New American Dream provides a cost calculator at www.newdream.org/water. By plugging in how many bottles of water your family consumes each year and the retail costs of that water, you’ll find out how much you could save by switching to filtered tap water.
