Dr. B.R. Ambedkar is widely celebrated as the chief architect of the Indian Constitution and campion of social justice. However, his transformative contributions to India’s water and power policy remain underappreciated in mainstream discourse. This paper explores Ambedkar’s key role in shaping India’s national water management framework and his vision for inclusive economic, infrastructural and sustainable development. As a visionary economist, social reformer, and statesman, Ambedkar championed policies that laid the groundwork for multipurpose river valley projects, state-led economic planning, and centralized control of natural resources. His efforts in institutional development, policy formulation, and technological foresight significantly advanced the principles of equity and sustainability in water governance. This study examines Dr. Ambedkar as a foundational figure in India's water policy landscape, whose legacy continues to influence the nation’s approach to resource management and social equity.
