I have 200 pecan trees on a drip irrgation system currently powered with gas pumps.  The water comes from a river about 30' below the orchard and about 800 feet to the most distant tree.  I currently pump to a holding tank about 150' from the river and then pump from the holding tank to the trees.  I would like to be able to deliver a minimum of 60 gallons/tree/day--12000 gallons in an 8 hour day.  Since the main water line goes down the middle of the orchard the longest path the water has to travel from the holding pond is 650'.  Can wind or solar power provide the necessary energy to do this job and what components would be needed.  I live in central Texas and have 5-10 mph winds about 140 days out of spring and summer and well over 240 sunny days/ year. Could one pump handle the job from the river or should I stick with a two pump system? I will monitor for replies. What if I reduced my need to 8000 gallons/day?
