Abstract

In contemporary conditions the existing Program for Rehabilitation of Irrigation Systems is widely spread in Georgia. In the project tasks, as a rule, notwithstanding the natural-climatic conditions and without justification of the necessity, there is requested reviewing of possibility to replace the gravity irrigation by drip irrigation. The article is dedicated to the appropriateness of such replacement in the course of rehabilitation of irrigation systems. To identify economic efficiency of such requirement, there has been reviewed one of the distributors of the general irrigation system, where the gravity irrigation is to be replaced by drip irrigation. For the both methods there are determined capital and operating costs and there are calculated the values of Pure Net Variation. It has been found that such replacement during the rehabilitation conditions is economically unjustified and is appropriate only when water shortage in a feeding source.
