Residential outdoor water use in the United States accounts for more than 9 billion gallons of water each day, mainly for landscape irrigation. Experts estimate that as much as 50 percent of this water is wasted due to over-watering caused by inefficiencies in irrigation methods and systems. Irrigation control technologies can significantly reduce over-watering by applying water only when plants need it.
WaterSense labeled irrigation controllers, which act like a thermostat for your sprinkler system telling it when to turn on and off, use local weather and landscape conditions to tailor watering schedules to actual conditions on the site, instead of irrigating using a controller with a clock and a preset schedule.
WaterSense labeled controllers allow watering schedules to better match plants' water needs. With proper installation, programming, and maintenance, homeowners and businesses can use WaterSense labeled controllers instead of standard clock-timer controllers on their existing systems, and no longer worry about wasted water.
Replacing a standard clock timer with a WaterSense labeled irrigation controller can save an average home nearly 7,600 gallons of water annually. If every home in the United States with an automatic sprinkler system installed and properly operated a WaterSense labeled controller, we could save $1 billion in water costs and 100 billion gallons of water across the country annually from not overwatering lawns and landscapes. That's equal to the annual household water needs of nearly 1.2 million average American homes. WaterSense labeled controllers can also be a water-smart solution for larger landscapes, including such as schools, hotels, and office buildings.
