ENVIRONMENTAL EFFECT OF LIFT IRRIGATION SCHEME-A CASE STUDY

Purandar Lift Irrigation scheme is on Mula-Mutha River near Pune in India envisaged to supply 4 TMC of water to drought prone area of Purandar, Daund, Haveli & Baramati. It is observed that the raw water quality available near source is far below the acceptable limits for surface water irrigation. The farmers are raising objections for supply of raw water for irrigation purpose. The main reason for the reluctance of the farmers in using available river water is undesirable organic & in organic impurities, blackish green color & obnoxious smell of water. The chemical analysis results indicate that BOD (Biological Oxidation Demand) & COD (Chemical Oxidation Demand) values of the river water used for irrigation purpose are above permissible limit
