I I I I I I I I I I I I I I I I I I I Water conservation projects/programs identified and evaluated in the study are shown in Tables ES-2 and ES-3. Table ES-2 focuses specifically on structural and on-farm water conservation projects/programs such as, concrete lining, lateral interceptors, reservoirs, tail water returns systems, drip/sprinkler irrigation, delivery flexibility and others. Table ES-3 evaluates the potential conservation opportunities associated with the reclamation and/or reuse of effluent, drain, ground, river and Salton Sea waters. Table ES-2 also presents the estimated water conservation potential (acre-feet/acre) and the component of water that is being conserved for each structural and on-fann conservation project/program. The projects/programs identified in Table ES-2 are not meant to be all-inclusive. Any verifiable on-farm water conservation practice would be considered for inclusion in a voluntary program. Because of the interrelationships between water conservation projects/programs, it is important to note that the estimated conservation potentials presented in Tables ES-2 and ES-3 cannot be totaled in order to determine the maximum conservation potential. Two examples of how conservation projects impact one another are as follows: 1. Implementing subsurface drip irrigation eliminates the generation of tail water and therefore eliminates the option of utilizing a tail water return system (TRS) for the same field to conserve water. 2. Widespread implementation of TRSs and lateral interceptors would significantly reduce the amount of tailwater and operational water to the drains, which would severely limit the conservation potential for reclamation and reuse of drain water. Conceptual reclamation and reuse projects are further delineated in Table ES-3 by the source of water that the project utilizes (i.e. drain, river, etc.) and the estimated conservation potential. For the purpose of this study, these conceptual projects are assumed to ultimately conserve Colorado River water. Draft: Subject To Revision 1/3/96 ES-2
