Center pivot irrigation usage has grown throughout the Wadi As-Sirhan Basin of Saudi Arabia in recent decades. Water is mined from depths as great as one kilometer (0.6 miles), pumped to the surface, and evenly distributed by sprinklers that rotate 360 degrees. Spurred by a government effort to strengthen its agricultural sector, cultivated land in Saudi Arabia grew from 162,000 hectares (400,000 acres) in 1976 to more than 3.2 million hectares (8 million acres) by 1993.
