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 new 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,” said 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’s advanced 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 exact 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), the leading independent laboratory specializing in scientific testing of irrigation equipment, evaluated one IrriGreen Genius head 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.
IrriGreen will exhibit at the Irrigation Show 2017 at the Orange County Convention Center, Orlando, Fla. on November 8-9, 2017. IrriGreen will demonstrate the IrriGreen Genius Irrigation System at booth #150.
The Botanic Garden at OSU
Established in 1935 as an arboretum, the Botanic Garden at Oklahoma State University (OSU) serves as an educational and recreational resource. The Botanic Garden supports interdisciplinary research and provides programming that fosters understanding and appreciation of the flora, fauna and environmental systems compromising the natural and man-made landscape of Oklahoma, thereby inspiring visitors to explore their relationship with the land. The gardens and grounds – designed and built by OSU students, staff, faculty, and volunteers – feature rock and water gardens, a children’s garden, a formal Japanese garden, small-space patio gardening, herbs and vegetables, native plants and grasses, prairie and wetland restoration, water-conserving xeriscaping, and a wildscape that attracts birds and butterflies.
