Sardar sarovar Dam on the life line of Gujarat -Narmada River


  • Estimated Cost - Rs. 392.4 billion (8 billion USD)
  • Main Dam - 1,210 m long, 163 m high from the deepest foundation level
    • World's Second Largest Concrete Gravity Dam (by volume) after Grand Coulee
    • World's Third Highest Spillway discharging capacity - 87,000 m3/second
  • Designed Live Storage Capacity of the Reservoir 5860 MCM (4.75 million acre feet)
  • Hydropower - 1,450 MW installed capacity (1 billion kWh every year)
  • Irrigation - 1.905 million Ha (1.8 million Ha. in Gujarat benefitting 1 million farmers)
  • Drinking Water - 9633 villages and 131 towns (29 million people)
  • Canal Network - 75,000 km length
    • Main Canal - 458.318 km long, capacity 1,133 m3/second, 633 structures
  • No. of Employees – 4673

A new era of water revolution has begun. The water has started flowing from Kevadia to Kutch... Villagers are provided water through pipelines instead of tankers...Rivers & Ponds are recharged...More than 15,000 villages are covered under Narmada Water supply project..Narmada main canal has reached upto Gujarat-Rajasthan border 458 km and Sub canal distribution network has covered more than 1000km.....
It was the late Sardar Vallabhabhai Patel who conceived the idea of constructing a dam over the river Narmada in 1946-47 for the optimum use of Narmada waters for the welfare of the Nation.
Today The Sardar Sarovar Project is one of the largest water resources project of India covering four major states - Maharashtra, Madhya Pradesh, Gujrat and Rajasthan. Dam's spillway discharging capacity (30.7 lakhs cusecs) would be third highest in the world. With 1133 cumecs (40000 cusecs) capacity at the head regulator, and 532 km. length, the Narmada Main Canal would be the largest irrigation canal in the world.
The project will generate between 856 to 1007 million units per year of cheap and Eco-friendly, indigenous hydropower. Project would meet the drinking water needs of 8215 villages, 135 urban centers and benefits three sanctuaries.
