Summer's rising temperatures often coincide with rising outdoor water use, primarily due to an increase in lawn and landscape watering. While using water efficiently is important throughout the year, sometimes the timing of water use can make a big difference for community water supplies—and your water bill.

In most areas, the amount of water homeowners use to keep their lawns green or gardens lush spikes in the summer—two to four times as much water than they use the rest of the year! And those with timed outdoor watering systems often forget to monitor the weather or set their irrigation controllers back in the fall, leading to more overwatering during the cooler months.

You can help use less water and create a healthier landscape by using and sharing these facts about overwatering and tips for reducing outdoor water use.

Facts about Summertime Overwatering

  • Depending on the region, homeowners use between 30 and 70 percent of their water outdoors.
  • Experts estimate that 50 percent of the water we use outdoors goes to waste from evaporation, wind, or runoff due to overwatering.
  • Review your water bills and compare your winter water use with your summer use to get a sense of how much extra water you use outdoors when it's hot.
