Our Mission

Billions of Gallons of Water Saved (And Counting)

Water waste is a big issue in the United States (particularly for western states), and things like excessive or unnecessary watering can make matters worse. The EPA estimates that up to 50 percent – yes, HALF – of the water we use outdoors "is lost due to wind, evaporation, and runoff caused by inefficient irrigation methods and systems." Rachio is working to fix this.

With the help of Rachio users across the country, we have been able to conserve more than 47 billion gallons of water since 2014.
