Namibia Grapes and Dates

Irritech was appointed by Silverlands Namibia to supply and install a bulk water transfer of 3.5km to get water from the Orange River to a booster station. A total elevation gain of 101m from the river to the highest grape block was overcome to push 3000 cubic meters an hour. Two giant barges were used to pump from the orange to the River booster station, the barges compensate for the large variation in water levels experienced on the lower parts of the orange. From the River Booster the water runs 3.5 km in three separate pipes, a 500mm, 450mm and 400mm running parallel to each other, to the in-field booster station. The in-field booster station the pumps filtered water to the grape and date blocks separately.
Seventy-three hectares of table grapes were irrigated using micro sprinklers, running laterals along the vineyard tensioning wires and hanging the sprinkler with a dropper to irrigate only the root area.
Fifty-three hectares of Medjool Dates was irrigated using adjustable arc nozzles, to keep the water away from the center of the tree while young as the center is susceptible to rotting if it gets moisture on it. Medjool dates require around 700 liters of water per day at full size.
