​Be Smart. Drink Tap…

There are plenty of reasons to drink Ann Arbor tap water (A2H2O): it's good for you, your wallet and the environment! For further information on the negative impacts of commercially-bottled drinking water in contrast to municipal tap water see the Bottled Water Issues Summary (PDF).

Be Safe

Did you know the US EPA closely regulates municipal tap water? Ann Arbor’s Water Treatment Plant lab staff and operators perform over 150,000 types of analysis on the City’s drinking water annually—some tests occur every hour. These tests monitor nearly 280 different substances, and the vast majority has never been detected. Tap water is more closely regulated than commercially-bottled water. Ann Arbor’s tap water is a frequent winner of the regional Michigan Water Tasting Competition, too!

Save Money​

Besides offering a safe and reliable source of water, Ann Arbor’s tap water is a great value. Refilling a 16-ounce water bottle from the tap costs less than one penny.  In fact, you can fill 4,000 16-ounce water bottles for less than one dollar.

Be Green 

Disposable water bottles generate substantial waste. Thousands of tons of plastic and millions of barrels of oil are used each year to make plastic water bottles for commercially-bottled water; millions of tons of carbon dioxide result from this process. Drinking tap water provides the opportunity to use refillable bottles rather than disposable ones.
