10 Biggest Dams in India

Dams are masterpiece of civil engineering wonders. They are considered to be one of the toughest and strongest tangible structures in the world. They are so powerful that even a high explosive shell could not bring a crack on its concrete walls easily. To block up massive rivers and to create hydroelectricity or simply control big reservoirs are not at all easy. The way they are built using tons of concrete blocks with a mix of stone, earth, bricks and steel is simply incredible.

Dams are very important for us to survive efficiently. They not only provide electrical energy to our houses but also provide water for domestic, industry and irrigation purposes. In India, there are nearly 4200 small and big dams that have been constructed by the end of the year 2016. Being rivers land, India has great potential to make a good amount of electricity production each year. Satluj Jal Vidyut Nigam (SJVN), National Hydroelectric Power Corporation (NHPC), Bharat Heavy Electricals Limited (BHEL) and National Thermal Power Corporation (NTPC) are few major Indian government organizations who are working ingeniously to strengthen DAMS projects in India.
