Landscape Landscape: Control Systems
Loading...
Manual systems keep you in touch with your garden and it’s water needs. You must decide each day if, when and how much to water. You must be there when it’s time to turn the system on and when it’s time to turn it off. Studies show that people with manual systems use less water than people with automatic systems.
       
Semi-Automatic systems, which work similar to a kitchen timer, require you to turn the water on manually but the system turns itself off at the end of the time (or number of gallons) you set.
       
Automatic systems are the most common type. They use an electronic controller to do all the work for you. Traditional automatic systems never forget to water . . . even if it’s raining. Because we can ignore automatic systems, studies show that people with these systems use more water than people with manual systems.
       
Smart systems, also known by the acronym SWAT (Smart Water Application Technologies) are now affordable for residential use. Smart systems add sensors and/or telemetry to the controller to adjust automatically for the day-to-day weather changes in your garden. Studies show that Smart controllers save a lot of water.
