Abstract: Various options are available as alternatives to the shallow, large-sized, earthen evaporation basins that are customarily constructed for disposal of agricultural drainage water in California. The authors present general performance characteristics for the following types of options: source control; drainage water reuse; land retirement; export to a sink; ground-water management; and treatment primarily for removal of trace-element contaminants, and secondarily for removal of salts. Each of the options show one or more limitations with respect to cost effectiveness, meeting environmental standards, engineering performance, or political acceptability. However, if combined into compatible mixes that are tailored to regional or local conditions, the options offer promise of outperforming traditional evaporation ponds, in areas subject to significant environmental constraints. Costs and plan design details are given.
