This study investigates the multifaceted significance of water in Indian society, emphasizing its roles as a vital resource for survival, a symbol of cultural heritage, and a cornerstone of ecological harmony. Through an integration of indigenous knowledge, cultural narratives, and contemporary scientific insights, this research explores the deeper connection between water, health, and well-being, highlighting its therapeutic and medicinal properties as understood in traditional practices. Employing a mixed-method approach, the study combines a comprehensive literature review with an analysis of historical, ethnographic, and field data. The findings underscore the holistic water management approaches embedded in indigenous knowledge systems, offering sustainable solutions to contemporary challenges such as water scarcity and pollution. By weaving principles of sustainable thinking, circular economy, and traditional water systems (TWS), the study demonstrates how these practices advocate a harmonious relationship with nature and provide sustainable frameworks for water governance. The research also emphasizes the potential of TWS to contribute to Sustainable Development Goal 6 (SDG 6) by aligning hydrological cycles, cultural practices, and resource management. In conclusion, the paper calls for the preservation and promotion of indigenous wisdom, advocating its integration with modern science to foster sustainable development and mitigate ecological challenges.
