Tap Water

Cambridge tap water is a safe, inexpensive, and healthy beverage that will help you stay hydrated and feel energized throughout the day.



What is tap water? Tap water is drinking water that comes from the public water supply and is available from sinks, faucets, or drinking fountains. 

Water contains zero sugar! Sugar-sweetened drinks- such as soda, juice and sports drinks- are the number one source of added sugar in our diets, which increases the risk of becoming overweight and also contributes to dental cavities.

Tips for Drinking More Water

  • Use a reusable water bottle for filling up on the go. Did you know that Cambridge has water bottle fillers in most parks and squares?
  • Add a piece of lemon, lime, cucumber, or mint leaf to water, adding flavor but without adding calories. Check out these flavored water recipes
  • Add a splash of 100% fruit juice to a glass of sodium-free carbonated water for a refreshing, bubbly drink.

Water Testing and Safety

Cambridge tap water is tested weekly in each neighborhood, ensuring that it is safe to drink.

The Cambridge Water Department offers free home tap water testing for lead and copper to Cambridge residents. Test kits are available to residents.

Annual drinking water quality reports from the Cambridge Water Department are available.
