More than 28 million homes across the United States have in-ground sprinkler systems, and most of those systems schedule watering with some sort of clock- based device. As a result, many homeowners waste water by irrigating their landscapes when they may not need it. Experts estimate that as much as half the water we use outdoors may go to waste due to inefficient irrigation methods and systems. Take control of your controller with a WaterSense labeled weather- based or soil moisture-based model. WaterSense labeled irrigation controllers can replace or upgrade clock-based controllers to better tailor watering schedules for landscapes. These smart technologies can override scheduled irrigation when there is sufficient moisture available so plants don't need water. Weather-based irrigation controllers tailor watering times based on local weather and landscape conditions, allowing irrigation schedules to better match plant water needs. Plants get water that is needed when it is needed. Soil moisture-based irrigation controllers—also known as soil moisture sensors—are a technology that can detect the amount of moisture in the ground. Both types of WaterSense labeled controllers can be purchased as stand-alone controllers or installed with existing controllers as "add-on" or "plug-in" devices that can be used in tandem with an existing clock-based device to help water more efficiently. SAVING WATER OUTDOORS These WaterSense labeled controllers, along with WaterSense labeled spray sprinkler bodies, provide consumers with a variety of smart irrigation technology options. With proper installation, programming, and maintenance, homeowners and businesses will reduce water waste outdoors and promote plant health.

The U.S. Environmental Protection Agency (EPA) estimates that installing a WaterSense labeled irrigation controller can save an average home with an automatic landscape irrigation system up to 15,000 gallons of water annually. LOOK FOR THE WATERSENSE LABEL! Homeowners and landscapers can look for both types of WaterSense labeled controllers for a new irrigation system or to upgrade an existing one.
