The Sardar Sarovar Project (SSP) is one of India’s most ambitious and transformative water resource development initiatives. Envisioned as a multi-purpose project to address the chronic water scarcity and power shortages in western India, it has evolved over decades into a symbol of engineering excellence, inter-state cooperation, and developmental perseverance. From its early conceptualization in the mid-20th century to its near-completion in the 21st, the SSP’s journey reflects the complexities and triumphs of large-scale infrastructure development in a diverse and democratic nation.
The need for the project was rooted in the persistent droughts and water stress faced by Gujarat and Rajasthan, coupled with the underutilization of the Narmada River’s vast potential. The project was designed to provide irrigation to millions of hectares, drinking water to thousands of villages and towns, and hydroelectric power to support regional growth. Its scale and scope made it a cornerstone of India’s strategy for integrated water resource management.
The vision for harnessing the Narmada River dates back to the 1940s, when initial surveys and feasibility studies were conducted. The formal foundation stone of the Sardar Sarovar Dam was laid by Prime Minister Pandit Jawaharlal Nehru in 1961, marking the beginning of a long and complex journey. However, progress was soon hindered by inter-state disputes over water sharing, which delayed construction for years.
To resolve these disputes, the Government of India established the Narmada Water Disputes Tribunal (NWDT) in 1969. After nearly a decade of deliberation, the tribunal issued its award in 1979, allocating water and power shares among Gujarat, Madhya Pradesh, Maharashtra, and Rajasthan. This legal framework provided the foundation for coordinated implementation. To oversee and regulate the project, the Narmada Control Authority (NCA) was established, ensuring inter-state cooperation and compliance with environmental and social safeguards.
The construction of the Sardar Sarovar Project was carried out in phases, each marked by significant technical, financial, and social challenges. The main dam, a concrete gravity structure, was built in stages, with its height gradually increased to the final level of 163 meters. This allowed for the creation of the Sardar Sarovar Reservoir, with a gross storage capacity of 9.5 billion cubic meters.
Parallel to the dam, the Narmada Main Canal was constructed, stretching over 460 kilometers in Gujarat and extending into Rajasthan. This canal, supported by a vast network of branch canals and distributaries, was designed to irrigate over 18 lakh hectares of land. The project also included the development of two major hydroelectric powerhouses—the River Bed Power House (RBPH) and the Canal Head Power House (CHPH)—with a combined installed capacity of 1,450 MW.
The project’s timeline spanned several decades, with construction beginning in earnest in the 1980s and major components reaching completion in the 2010s. The scale of resources mobilized was immense, involving thousands of engineers, workers, and planners, as well as significant financial investment from both national and international sources.
Today, the Sardar Sarovar Project is nearly fully operational. The dam, reservoir, powerhouses, and main canal are functioning as intended, delivering water and power to millions. Irrigation has transformed previously barren lands into fertile agricultural zones, while drinking water pipelines have reached over 9,000 villages and 173 towns. The hydroelectric power generated supports regional energy needs and contributes to India’s renewable energy goals.
Water releases are now managed in a coordinated manner to balance the needs of irrigation, drinking water, and power generation. The NCA continues to play a key role in ensuring equitable distribution and monitoring compliance with the NWDT award. The project also provides flood moderation benefits during the monsoon season, protecting downstream areas from inundation.
The Sardar Sarovar Project stands as a testament to India’s ability to conceive, plan, and execute large-scale infrastructure projects despite numerous challenges. Its legacy is one of resilience, innovation, and long-term vision. As the country continues to grapple with water scarcity and climate variability, the SSP offers valuable lessons in integrated river basin development, inter-state collaboration, and sustainable resource management.
