There are many aspects of the project for interlinking the peninsular rivers - conceptual, technical, environmental and economic - which need careful, detailed and objective review by independent experts and there has to be open public discussion of issues before the project is taken up for implementation. A proper review of the project must assess both its technical feasibility and whether the costs of increasing effective supply (including environmental and rehabilitation costs) by augmentation through interlinking is commensurate with the benefits by way of increased production. It must also be examined whether there is scope for improving efficiency of use beyond what is assumed, what the costs and benefits would be and how they will compare with those of interlinking
