Disadvantages of Multi-purpose Projects

Authorized multi-purpose projects in India have proactively identified amazing results in creating the potential of water systems and adding to it the hydroelectric age. So far, the irrigation potential generated by large and medium-sized enterprises has increased from 10 million hectares in 1950-51 to 3 million hectares in 1997-98. The total discharge limit of hydropower companies in India also increased from 0.6 GW in 1950-51 to 21.7 GW in 1996-97. Despite the achievements made, multi-reason projects in India are still on display in the accompanying discussions.

• Excessive benefits of irrigation: It has been suggested that the benefits of hydraulic systems identified from multi-purpose projects are overestimated on the grounds that the actual inundated areas of these undertakings are significantly less due to delays in the development of canals and streams on the mainland. In addition, the delay in completing these undertakings has resulted in a sharp increase in its costs.
• The biggest cost of hydroelectricity: Despite the fact that hydropower has low operating costs, sustainable and environmentally friendly sources and moreover it has a long growth period, the postponement of business appointments due to rapidly increasing risk costs and start-up costs soar. Each of these results in a similarly higher age unit cost for hydropower.
• Little benefit in terms of flood control: Multi-cause projects have also neglected to identify the greatest flood control benefits, as embankments, discharge channels, and flood safety plans have failed miserably to deliver results.
• Bad impact on the environment: Finally, multi-cause projects come from severe adverse natural impacts related to the degradation of soil content due to waterlogging and soil salinity in its order zones. Acknowledging these negative aspects, Dr. B.B. Vora rightly commented, “The fate of the primary and medium water systems is weak and the country has neither the assets nor the ideal opportunity to add raw capacity to the approximately 26 million hectares of water systems through Doha. Therefore, small water supply systems, especially using groundwater, should be the mainstay everywhere in the future.

However, performing small tasks leads to maximum use of water resources and better control.

The advantages of Multipurpose River Projects include the generation of electricity, domestic as well as industrial water supply, control of floods, inland navigations, and fish breeding. The disadvantages of Multipurpose River Projects include higher investment costs, outdoor activities, inland navigation as well as fish breeding.

The multi-objective task is to rationally manage the country’s water resources. Multipurpose business is a huge business that caters to different needs like flood control, fish farming, water systems, energy age, soil conservation, and more. However, hydroelectric projects are those that are fundamentally concerned with the supply of legitimate energy. Individuals always want to store water from springs during the monsoon season for use in the dry season. Individuals in ancient India created many pressurized structures such as dams, artificial lakes, reservoirs, and moats to store and redirect water to the water supply system.
