The objective of this paper is to evaluate the economic feasibility of constructing tail-water recovery systems as a source for supplemental irrigation water in the Mississippi Delta.Depending on the discount rate selected, conversion of a furrow irrigated 160 acre tract to a tailwater recovery system would result in a reduction in net present value ranging from $149,928 at a 10% discount rate to a reduction of $162,019 at a 5% discount rate over the ten-year planning horizon.
