Water Your Lawn in the Early Morning or Evening
Why it’s worth the effort: If you irrigate in the middle of the day, evaporation prevents 14 percent of the water from reaching the plants’ roots. Watering the lawn in the early morning or evening can save the typical home owner 87 gallons a week.
Your one-year effect: 4,524 gallons of water saved.
The effect if every household in the U.S. did it for one year: Equal to nine times the annual rainfall in Seattle.
Water Your Lawn With a Hose, Not a Sprinkler
Why it’s worth the effort: The average single-family home pours at least 25,000 gallons of water a year on the lawn―more than double the amount used inside. People are smarter than automatic sprinklers: Watering with a hose is at least twice as efficient.
Your one-year effect: 12,500 gallons of water saved.
The effect if every household in the U.S. did it for one year: Equal to the volume of water in Shasta Lake, in Northern California.
