Water, an indispensable element of life, has been a fundamental resource for the sustainability and development of human civilization since its inception. Throughout history, societies have settled around water sources, developed advanced irrigation systems, and devised strategies to preserve and manage these resources. However, arid and semi-arid regions worldwide present a unique paradox of water challenges and scarce environments rich in technology and innovation. One such paradigm is exemplified by Jaipur’s traditional water management system, which is a testament to human ingenuity during times of adversity. Jaipur, the capital city of Rajasthan, lies in the semi-arid desert region of India. This geographical location has a unique combination of weather conditions with extremely hot summers and uneven and scant rainfall throughout the year. This study aims to explore the significance of traditional water management systems in Jaipur and examines how these structures are used for water-utilitarian solutions in semi-arid regions. The water management system of Jaipur was designed to efficiently accommodate the water needs of its residents through rainwater harvesting. These structures were designed to capture rainwater and store it for dry periods, reflecting a deep understanding of local hydrology and exhibiting a harmonious integration of engineering with functionality. Nevertheless, the challenges of the modern era, such as population growth, urbanization, climate change, and increased water demand, have prompted the need for innovative solutions beyond traditional methods. Hence, a comprehensive research methodology with a multidisciplinary research design was adopted to achieve this objective. It involved an architectural analysis that examined the structural layout, focusing on features such as stepwells, underground channels, and storage reservoirs, and hydrological assessments that involved studying the hydrology of the region and catchment areas of the forts, along with rainwater harvesting and groundwater recharge techniques. By employing this comprehensive research methodology, this study highlights the adaptation of these structures to modern water needs and their contribution to the community’s water security and examines how these water management techniques are used worldwide as innovative technologies to transform water management. The relevance of this study extends beyond historical curiosity as it provides valuable insights for present-day water resource management in arid and semi-arid regions that deal with water scarcity exacerbated by climate change. By analyzing the sustainability of these traditional water management systems, this study offers potential solutions for adapting and modernizing these techniques to the current challenges. This bridges the gap between historical wisdom and modern innovation, underlining the importance of incorporating traditional knowledge into sustainable water management strategies. By examining the traditional water management systems in Jaipur, this study sheds light on the enduring wisdom of the past and its applicability in addressing existing water challenges. These findings have implications for policymakers, urban planners, and researchers working toward sustainable water management solutions in arid and semi-arid regions worldwide.
