Abstract: Society is beginning to productively utilize materials which in the past were considered waste. San Joaquin Valley growers are also beginning to manage drainage water, salt, and selenium as resources rather than disposing of them as a waste. Drainage water is being sequentially reused to irrigate trees and plants of progressively increasing salt tolerance. About 80 to 85 percent of drainage water is used to produce marketable commodities. Plants uptake selenium, and they can be harvested as "selenium enriched forage" for livestock feeding in selenium deficient areas. About 15 to 20 percent of the final volume of drainage water is discharged into a solar evaporator to evaporate water and crystallize salt. Initial research and development efforts indicate the possibility of producing marketable commodities from salt. The concept of managing drainage water, salt, and water as resources, as well as technical data from multi-year research, are presented in this paper.
