Existing System: Solid Set, 23 degree impacts on risers, 30+ foot spacing

Compared System: Center Pivot or Lateral Move System (40 acres)

¹Potential No. of Irrigation Systems Affected	50
Estimated Water Savings (%)	20 (10 to 30)
²Average Year Water Savings (million gal.)	73
³Dry Year Water Savings (million gal.)	130
Est. Cost of Full Implementation on Avg. System ($, 1998)	$20,000
Statewide Costs for Full Implementation ($, 1998)	$1,000,000
Cost / Unit of Water Saved in Average Year ($, 1998 / million gal.)	$13,153

These comparisons are for general interest and are not necessarily the most cost effective alternatives. Also, the potential impacts of changing from one system to another requires much more specific information about field conditions, field shapes, etc. Irrigators considering complete replacement of an irrigaton system should consult with an irrigation specialist for available options.
