Drip could be flexible enough for the wide-ranging water requirements, seven different microclimates and five different soil conditions. It could deliver water with precise control, avoiding overspray and water waste. And drip could uniformly irrigate in the midst of large, dense plantings. For a design concept ensuring low-maintenance irrigation, Abney devised a system of tubing that forms a series of loops. The loops keep water moving in all directions, reducing the chances of clogging and ensuring that a zone can irrigate if one line is damaged.
Pressure gauges at each zone indicate clogging or a broken line.
Well Abney specified Rain Bird's complete line of Xerigation products. The spreading root system of trees required equally wide coverage. At the heart of the system is Rain Bird's ESP-MC controller. Stations can water up to 12 hours which is perfect for drip. ESP-MC's four programs accommodate the range of water requirements while its eight start times help to reduce runoff.
