Lawn Irrigation System Features Programmable Sprinkler Heads, Uses 40 Percent Less Water

Lou Anella, Ph.D. is professor of horticulture and landscape architecture at Oklahoma State University (OSU). He also serves as the director of the OSU Botanic Garden. His search for a lawn irrigation system ended when he found the IrriGreen Genius Irrigation System, which students in his irrigation class installed at the Botanic Garden.

“In research, in the classroom and at the Botanic Garden, we emphasize resource conservation, sustainable design and environmental stewardship,” says Anella. “That’s why I introduce new technologies to my irrigation students (including landscape management and landscape architecture majors), visitors to the Botanic Garden, and viewers of ‘Oklahoma Gardening’.”

Anella said IrriGreen technology contains its sprays within the outline of the lawn, following every curve and corner. There is no wasted water from spraying past the lawn onto sidewalks.

IrriGreen’s patented software, integrated into its programmable Genius Sprinkler Heads, digitally controls water pressure, the direction and distance of the water sprays, and the rotational speed of the heads. Utilizing mapping points set by installers with the IrriGreen Mobile App, the system modifies the sprays up to 437 times per rotation so the watering patterns conform to the shape of the lawn. IrriGreen sprays water with the precision of an inkjet printer spraying ink on a page.

Landscape irrigation accounts for nearly nine billion gallons of water per day in the U.S. According to the Environmental Protection Agency (EPA), as much as half is wasted because of the inefficiency of sprinkler systems with mechanical sprinkler heads.

The Center for Irrigation Technology (CIT), an independent laboratory specializing in scientific testing of irrigation equipment, evaluated one IrriGreen Geniushead per irrigation zone against conventional systems with six to nine mechanical rotors or spray heads. IrriGreen increased soil moisture by equivalent amounts, but used 40 percent fewer gallons of water.

The Botanic Garden installation covers 10,000 square feet of lawn with five irrigation zones. IrriGreen requires only one computerized smart head in the center of each zone. Conventional systems need six to nine mechanical spray heads or rotors arrayed all around the outside of each zone. With less trenching; less pipe to lay and less wire to connect; fewer valves and fittings; and a smaller number of holes to dig; the system saved labor and minimized disruption to the landscape.
