Why in news?
Nine workers and engineers conducting a bridge survey on the Mir Alam Tank in Hyderabad were rescued after their boat’s engine failed. The Hyderabad Disaster Response and Asset Protection Agency (HYDRAA) navigated through dense water hyacinth to bring the stranded team back to shore. The incident drew attention to safety measures on water bodies and the lake’s historical significance.
Background
Mir Alam Tank is a historic reservoir located near the Nehru Zoological Park in Hyderabad. It was constructed between 1804 and 1806 under the patronage of Mir Alam Bahadur, the prime minister of the erstwhile Hyderabad State. Designed by French engineer Michel Joachim Marie Raymond, the tank features a series of twenty‑one semicircular arches that function as a multi‑arch dam. It served as Hyderabad’s primary source of drinking water until the late nineteenth century and now forms part of the city’s heritage and recreational landscape.
Key points about the tank
- Architectural design: The dam’s segmented arches make it a unique engineering marvel. They distribute water pressure evenly and reduce the risk of collapse.
- Recreation hub: The reservoir is adjacent to a popular park and offers boating and picnicking opportunities. Migratory birds visit the wetlands during winter.
- Challenges: Overgrowth of water hyacinth and siltation have affected water quality and navigation. Urban encroachment and pollution also threaten the tank’s ecosystem.
Recent rescue operation
- During a routine survey for a proposed bridge, workers became stuck when their boat’s motor malfunctioned. Dense vegetation made it difficult to paddle back.
- HYDRAA responded promptly, using another boat to reach the stranded team. Rescuers cut through the weeds and safely escorted everyone to shore.
- The incident highlighted the need for better maintenance of the water body and safety protocols for workers.
Significance
- Cultural heritage: Mir Alam Tank is a reminder of Hyderabad’s hydraulic engineering heritage and the foresight of its rulers.
- Urban ecology: The lake supports local wildlife and mitigates urban heat. Proper management can enhance biodiversity and recreational value.
- Public safety: Regular clearing of hyacinth and strict safety standards are essential for protecting workers and visitors.
Conclusion
The rescue at Mir Alam Tank underscores both the challenges of managing historic water bodies and their enduring importance to urban life. Ongoing conservation and infrastructure improvements will ensure that this 200‑year‑old reservoir remains a cherished landmark.
