The Sardar Sarovar Dam is a concrete gravity dam built on the Narmada River near the town of Kevadiya, in Narmada District, in the Indian state of Gujarat. The dam was constructed to provide water and electricity to the Indian states of Gujarat, Madhya Pradesh, Maharashtra and Rajasthan.
India's first Prime Minister Jawaharlal Nehru laid the foundation of the project on 5 April 1961. [2] The project took form in 1979 as part of a development scheme funded by the World Bank through their International Bank for Reconstruction and Development, to increase irrigation and produce hydroelectricity, using a loan of US$200 million. [3] The construction for dam begun in 1987, but the project was stalled by the Supreme Court of India in 1995 in the backdrop of Narmada Bachao Andolan over concerns of displacement of people. In 2000–01 the project was revived but with a lower height of 111 meters under directions from SC, which was later increased in 2006 to 123 meters and 139 meters in 2017. The Sardar Sarovar Dam is 1210 meters long. [4] The dam was inaugurated in 2017 by Prime Minister Narendra Modi. [5] The water level in the Sardar Sarovar Dam eventually reached its highest capacity at 138.7 metres on 15 September 2019. [6] [7]
As one of the 25 dams planned on river Narmada, the Sardar Sarovar Dam is the largest structure to be built. It is the second largest concrete dam in the world in terms of the volume of concrete used in its construction, after the Grand Coulee Dam across the Columbia River, US. [8] [9] It is a part of the Narmada Valley Project, a large hydraulic engineering project involving the construction of a series of large irrigation and hydroelectricity multi-purpose dams on the Narmada River. After a number of cases before the Supreme Court of India (1999, 2000, 2003), by 2014 the Narmada Control Authority had approved a series of changes in the final height and the associated displacement caused by the increased reservoir, from the original 80 m (260 ft) to a final 163 m (535 ft) from foundation. [10] [11] The project will irrigate 1.9 million hectare area, most of it in drought prone areas of Kutch and Saurashtra.
The dam's main power plant houses six 200 megawatts (MW) Francis pump-turbines to generate electricity and include a pumped-storage capability. Additionally, a power plant on the intake for the main canal contains five 50MW Kaplan turbine-generators. The total installed capacity of the power facilities is 1,450 MW. [12] The tallest statue in the world, the Statue of Unity, faces the dam. This statue has been created as a symbol of tribute to Vallabhbhai Patel. [13]
The dam is located in Gujarat's Narmada district and Kevadia village, on the border of Gujarat and Maharashtra. To the west of the dam, is Madhya Pradesh's Malwa plateau, where the Narmada river dissects the hills tracts and culminates in the Mathwar hills. [14]
The dam is 1,210 meters long and stands 163 meters tall. The Sardar Sarovar reservoir has a gross capacity of 0.95 million hectares meter and live storage capacity of 0.586 million hectares meter. It occupies an area of 37,000ha with an average length of 214 km and width of 1.7 km. The river catchment area above the dam site is 88,000 square kilometers. It has a spillway discharging capacity of 87,000 cubic meters a second. [15] This dam is one case study to learn about Integrated River Basin Planning, Development and Management. [16]
The reservoir operation in the catchment area during the monsoons (from July to October) is well synchronized with the rain forecast. The River Bed Power House (RPBH) is responsible for strategically maximizing the annual allocation of water share. It ensures that minimum water flows downstream, and maximum water is used in the dam overflow period (generally in Monsoons). In non-monsoon months, RPBH takes measures to minimize the conventional and operational losses, avoiding water storage, restricting water intensive perennial crops, adoption of underground pipelines, proper maintenance of canals, related structures and operation of canals on a rotational basis. [17]
This project was envisioned by the first Home Minister of India, Sardar Vallabhbhai Patel. Jawaharlal Nehru laid the foundation stone of this project in 1961. A thorough survey was carried out by his government to study the usage of the Narmada River which flows through states of Madhya Pradesh and Gujarat to the Arabian Sea. [18]
As the river was shared between the three states (Gujarat, Maharashtra and Madhya Pradesh) there were disputes regarding sharing of water and other important resources. As the negotiations were not successful a report was created, and the Narmada Water Dispute Tribunal (NWDT) was established in 1969. In 1979 the NWDT gave its verdict after assessing all the reports. [19]
This dam is called 'the lifeline of Gujarat'. Seventy five percent of Gujarat's command area is considered a drought prone area, this dam will cater for domestic water supply to the regions of Kutch and Saurashatra. In 2021, for the first time Sardar Sarovar Dam provided waters for irrigation in summers. [20]
The dam irrigates 17,920 km2 (6,920 sq mi) of land spread over 12 districts, 62 talukas, and 3,393 villages (75% of which is drought-prone areas) in Gujarat and 730 km2 (280 sq mi) in the arid areas of Barmer and Jalore districts of Rajasthan. The dam provides drinking water to 9490 villages and 173 urban centers in Gujarat; and 1336 villages and 3 towns in Rajasthan. The dam also provides flood protection to riverine reaches measuring 30,000 ha (74,000 acres) covering 210 villages and Bharuch city and a population of 400,000 in Gujarat. [21] Saurashtra Narmada Avtaran Irrigation is a major program to help irrigate a lot of regions using the canal's water.
In 2011, the government of Gujarat announced plans to generate solar power by placing solar panels over the canal, making it beneficial for the surrounding Villages to get power and also helping to reduce the evaporation of water. The first phase consists of placing panels along a 25 km length of the canal, with a capacity for up to 25 MW of power. [22]
The Government of Gujarat constructed a statue of Sardar Vallabhbhai Patel as a symbol of tribute. The statue stands in front of the dam and is considered as one of the major tourist attraction. [23]
The Narmada Water Dispute Tribunal, setup by Indian government has provided a policy framework under which rehabilitation of affected people has been implemented. The guiding principles of this policy are:
According to a research paper and survey done by Swaminathan S. Anklesaria Aiyar and Neeraj Kaushal: "Are Resettled Out sees from the Sardar Sarovar Dam Project Better off Today than their Former - despite implementation glitches, those displaced were far better off than their former forest neighbors in ownership of a range of assets including TVs, cellphones, vehicles, access to schools and hospitals, and agricultural markets. The gap in asset ownership and other outcomes between the treatment and comparison groups was often statistically larger if the heads of the household were illiterate compared to the gap if they were literate. This finding suggests that resettlement helped vulnerable groups more than the less vulnerable and that fears that resettlement will destroy the lives and lifestyles of tribal have been grossly exaggerated." [25]
The dam is one of India's most controversial, and its environmental impact and net costs and benefits are widely debated. [26] The World Bank was initially funding, but withdrew in 1994 at the request of the Government of India when the state governments were unable to comply with the loan's environmental and other requirements. [27] The Narmada Dam has been the center of controversy and protests since the late 1980s. [28]
One such protest takes center stage in the Spanner Films documentary Drowned Out (2002), which follows one tribal family who decide to stay at home and drown rather than make way for the Narmada Dam. [29] An earlier documentary film is called A Narmada Diary (1995) by Anand Patwardhan and Simantini Dhuru. The efforts of Narmada Bachao Andolan ("Save Narmada Movement") to seek "social and environmental justice" for those most directly affected by the Sardar Sarovar Dam construction feature prominently in this film. It received the (Filmfare Award for Best Documentary-1996). [30]
The figurehead for most part of the protest is Medha Patkar, the leader of the NBA. [31] Patkar's role is questioned in the protest as she is accused of money laundering. [32] Other notable figures who participated in the protest were Baba Amte, Arundhati Roy and Aamir Khan. [33]
The Narmada River, previously also known as Narbada or anglicised as Nerbudda, is the 5th longest river in India and overall the longest west-flowing river in the country. It is also the largest flowing river in the state of Madhya Pradesh. This river flows through the states of Madhya Pradesh and Gujarat in India. It is also known as the "Lifeline of Madhya Pradesh and Gujarat" due to its huge contribution to the two states in many ways. The Narmada River rises from the Amarkantak Plateau in Anuppur district in Madhya Pradesh. It forms the traditional boundary between North and South India and flows westwards for 1,312 km (815.2 mi) before draining through the Gulf of Khambhat into the Arabian Sea, 30 km (18.6 mi) west of Bharuch city of Gujarat.
The Sabarmati River is one of the major west-flowing rivers in India. It originates in the Aravalli Range of the Udaipur District of Rajasthan and meets the Gulf of Khambhat of Arabian Sea after travelling 371 km (231 mi) in a south-westerly direction across Rajasthan and Gujarat. 48 km (30 mi) of the river length is in Rajasthan, while 323 km (201 mi) is in Gujarat.
Narmada Bachao Andolan is an Indian social movement spearheaded by native tribals (adivasis), farmers, environmentalists and human rights activists against a number of large dam projects across the Narmada River, which flows through the states of Gujarat, Madhya Pradesh and Maharashtra. Sardar Sarovar Dam in Gujarat is one of the biggest dams on the river and was one of the first focal points of the movement. It is part of the Narmada Dam Project, whose main aim is to provide irrigation and electricity to people of the above states.

The Indira Sagar Dam is the largest dam in India, in terms of volume of water stored in the reservoir. It is located on the Narmada River at the town of Narmada Nagar, Punasa in the Khandwa district of Madhya Pradesh in India. The foundation stone of the project was laid by the prime minister of India Indira Gandhi on 23 October 1984. The construction of the main dam started in 1992. The downstream projects of ISP are Omkareshwar, Maheshwar, and Sardar Sarovar Project. To build it, a town of 22,000 people and 100 villages was displaced.
The Aji River is one of the main rivers of the Saurashtra region in Gujarat, India. Aji I dam on this river is called the lifeline of Rajkot City and separates Rajkot in east-west parts. There are four dams on Aji River, the water from which is used for agriculture and as drinking water.
Interbasin transfer or transbasin diversion are terms used to describe man-made conveyance schemes which move water from one river basin where it is available, to another basin where water is less available or could be utilized better for human development. The purpose of such water resource engineering schemes can be to alleviate water shortages in the receiving basin, to generate electricity, or both. Rarely, as in the case of the Glory River which diverted water from the Tigris to Euphrates River in modern Iraq, interbasin transfers have been undertaken for political purposes. While ancient water supply examples exist, the first modern developments were undertaken in the 19th century in Australia, India and the United States, feeding large cities such as Denver and Los Angeles. Since the 20th century many more similar projects have followed in other countries, including Israel and China, and contributions to the Green Revolution in India and hydropower development in Canada.
The Kalpasar Project or the Gulf of Khambhat Development Project envisages building a 30 km dam across the Gulf of Khambat in India for establishing a huge fresh water coastal reservoir for irrigation, drinking and industrial purposes. The project with 30 km sea dam will have the capacity to store 10 billion cubic meters fresh water, equating to 25% of Gujarat’s average annual rainwater flow, from the rivers like Narmada, Mahi, Dhadhar, Sabarmati, Limbdi-Bhagovo, and two other minor rivers. A 10 lane road link will also be set up over the dam, greatly reducing the distance between Saurashtra and South Gujarat. The project, which will create world's largest freshwater lake in marine environment, will cost INR90,000 crore or US$12.75 billion excluding the cost of tidal power plant. Project entails construction of the main "Kalpasar dam" across Gulf of Khambat and another Bhadbhut barrage on Narmada river, as well as a canal connecting the two.

It depicts Indian statesman and independence activist Vallabhbhai Patel (1875–1950), who was the first deputy prime minister and home minister of independent India and an adherent of Mahatma Gandhi. Patel is highly respected for playing a significant role in the political integration of India. The statue is located in Gujarat on the Narmada River in the Kevadiya colony, facing the Sardar Sarovar Dam 100 kilometres (62 mi) southeast of the city of Vadodara.
Narmada Valley Development Authority (NVDA) concerns Narmada River, the river of Madhya Pradesh. With 87% of its catchment area lying in Madhya Pradesh, it becomes all the more important for the state to exploit this enormous water resource. It was with this motto in mind that the Narmada Valley Development Authority (NVDA) was formed by the government of MP on 9 August 1985. NVDA oversees all major development projects in the Narmada Basin. The body also ensures that proper rehabilitation is provided to the displaced, and the negative impacts on environment are minimized by taking appropriate measures.
