Urban water stress is a growing challenge, especially in rapidly developing cities like Delhi. In his insightful article, Dr. Manu Gupta, Co-Founder of SEEDS (Sustainable Environment and Ecological Development Society), explores the revival of the Hauz-i-Shamsi, an 800-year-old reservoir in Mehrauli, Delhi, as a model for sustainable urban water management. Built in AD 1130 by Shams-ud-din Iltutmish, Hauz-i-Shamsi was designed to harvest rainwater, a practice that has become crucial in today's climate-stressed world. Dr. Gupta highlights how the restoration of this historical water system has not only addressed water scarcity but also rejuvenated community engagement and environmental stewardship. By combining ancient wisdom with modern ecological practices, this project underscores the potential of heritage conservation in tackling contemporary urban challenges, offering a blueprint for sustainable development in other water-stressed regions.

Harnessing Ancient Wisdom for Modern Challenges: The Hauz-i-Shamsi Revival and Its Impact on Urban Water stress
The Hauz-i-Shamsi, a 800-year-old reservoir located in Mehrauli, Delhi, was constructed in AD 1130 by Shams-ud-din Iltutmish. This architectural wonder was strategically designed to harvest rainwater in the Aravalli region during the monsoon season. Having gone to seed over the past few decades, the revival of Hauz-i- Shamsi emerges not only as an act of historical preservation but as a strategic move in combating the modern crisis of urban water stress. Dr. Manu Gupta, Co-founder of SEEDS (Sustainable Environment and Ecological Development Society) who has been deeply involved in this project, discusses how community involvement in the revival of the ancient water management systems can teach us valuable lessons in sustainable urban planning to tackle urban water stress.
Why Hauz-i-Shamsi Matters
According to Dr. Gupta, "Hauz-i-Shamsi is integral to Delhi's history, representing one of the city’s initial layers. As one of the early sources of drinking water for Delhi's population, its revival speaks volumes about reconnecting with our heritage." The Hauz originally functioned as a large tank with a complex aqueduct system feeding other historical sites, including Tughlakabad Fort that is 10 km away. Over the years, this intricate water system was neglected, mirroring the broader neglect of urban heritage across rapidly urbanizing India.
Revitalizing Community and Environment
The project has sparked a remarkable transformation in local community engagement. Residents who once overlooked the reservoir now actively contribute to its maintenance. This shift is crucial in areas prone to urban water stress, where local stewardship can significantly enhance water security. "The revival has not only restored the reservoir but has also revitalized community interest and involvement in sustainable water use," Dr. Gupta remarks.
The restoration of Hauz-i-Shamsi addresses several layers of environmental challenges, particularly urban heat islands and water scarcity. Dr. Gupta notes, "By reviving ancient water conservation practices, we're directly combating the effects of climate change and reducing the city's vulnerability to urban water stress." The project employs nature-based solutions like bio-islands to purify the water, demonstrating how community efforts can integrate with modern ecological science to sustain urban centers.
Challenges and Pathways to Sustainable Water Management
The revival process had to overcome many challenges, from bureaucratic red tape to revitalizing community interest. Dr. Gupta shares, "It took a concerted effort to navigate through the complex web of local authorities and to re-engage the community." The successful collaboration among various stakeholders highlights the potential for similar initiatives across other cities that are vulnerable to water stress.
Dr. Manu Gupta, an advocate for nature-based solutions, critiques traditional disaster mitigation strategies involving bricks and concrete. He points out that embankments in Bihar, which have been around for 150 years, have failed to resolve the State's flooding issues. Similarly, he notes the inadequacy of sea walls in protecting against tsunamis, as they still result in loss of lives. Dr. Gupta emphasizes that nature-based approaches are proving more effective in extreme situations. For instance, he suggests that simple, understandable, and sustainable natural solutions could be more enduring and effective than structural interventions for managing lake-related disasters.
The twin lakes located near the Bengaluru Airport have been successfully rejuvenated, allowing farmers to resume agricultural activities. Birds are also returning to the area, indicating a positive ecological impact. A spokesperson from SEEDS highlighted the relative ease of working on smaller lakes. This particular lake near the airport features 7-8 rajakaluve (storm water drains), which had been blocked by silt accumulation. The SEEDS team undertook the task of clearing this silt, which in turn allowed the lake to naturally refill with water annually, sustaining the renewed life around it.
Conclusion
The Hauz-i-Shamsi revival serves as a blueprint for other regions facing similar challenges. This project is not just about preserving a piece of history; it's about reactivating a sustainable urban water management system that is vital for our survival in face of the increasing urban water stress conditions. The initiative stands as a compelling example of how ancient solutions can meet contemporary needs, fostering a sustainable relationship between heritage and modern urban resilience.
