Estimated water savings are between 0 and 10 percent. No water savings would be expected from systems which are already operating only at night and using good practices. The high end is associated with system which operate continuously through 24 hours in very open areas. The average estimated water savings is about 5%.

Of the 8,000+ center pivot systems currently in the state of Georgia, 50 are estimated to be candidates for this type improvement. However with the adoption of this sprinlkler package is the growers requirement to adopt a different tillage practice called "furrow diking". Not all individuals will adopt this tillage change. All systems with reduced angle impact sprinklers on top of the pivot are not candidates for the change due to the limitation on soil intake rates. The potential water savings from this practice alone would be about 48 million gallons during an average year. The cost to implement such a change is about $4,500 per system if a booster pump is required. The estimated statewide costs for full implementation is $0.225 million. The cost per unit water saved is estimated to be about $4,735 per million gallons of water saved. The spray nozzles will apply more water in a smaller area than the impact sprinklers at a higher pressure. As with all sprinkler packages, caution must be taken so that the instantaneous application rates remain below the minimum soil infiltration rate along the length of the pivot, especially nearest the end towers where higher ground speed forces the application rates to increase in order to maintain the same total application along the entire length of the pivot. Alternatively runoff can be minimized through enhanced infiltration of conservation tillage or temporary ponding in furrow dikes.
