Four Indian states, Gujarat, Madhya Pradesh, Maharastra and Rajasthan, receive water and electricity supplied from the dam . The foundation stone of the project was laid out by Prime Minister Jawaharlal Nehru on April 5, 1961 . The project took form in 1979 as part of a development scheme to increase irrigation and produce hydroelectricity . The dam was inaugurated by Prime Minister Narendra Modi on September 17, 2017 . </P> <P> One of the 30 dams planned on river Narmada, Sardar Sarovar Dam (SSD) is the largest structure to be built . It is one of the largest dams in the world . It is a part of the Narmada Valley Project, a large hydraulic engineering project involving the construction of a series of large irrigation and hydroelectric multi-purpose dams on the Narmada river . Following a number of controversial 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 . The project will irrigate more than 18,000 km (6,900 sq mi), most of it in drought prone areas of Kutch and Saurashtra . </P>
