The Archaeological Survey of India determined that the Kalingarayan Canal aqueduct in Erode, Tamil Nadu, is structurally stable [1].
This finding ensures the long-term viability of an ancient irrigation system that remains a critical piece of regional heritage. The assessment allows conservationists to shift their focus from emergency structural reinforcement to targeted maintenance of the masonry.
According to the ASI, the overall integrity of the aqueduct is sound [1]. However, the agency identified water seepage through masonry joints as the primary issue requiring conservation [1]. This specific degradation can lead to gradual erosion if not addressed through professional restoration techniques.
"ASI confirms Erode's Kalingarayan Canal aqueduct is structurally stable, with water seepage being the main issue requiring conservation," the ASI said [1].
The agency's evaluation focused on the physical stability of the stone and mortar components. While the structure is not at risk of immediate collapse, the seepage indicates a need for specialized grouting and joint repair to prevent future deterioration [1].
Efforts to preserve the canal system are part of a broader mandate to protect historic water management infrastructure in Tamil Nadu. The ASI will now prioritize the sealing of masonry joints to ensure the aqueduct continues to withstand environmental pressures, a necessary step for the site's preservation [1].
“The Archaeological Survey of India determined that the Kalingarayan Canal aqueduct in Erode, Tamil Nadu, is structurally stable.”
The determination of structural stability prevents the need for invasive reconstruction of the aqueduct. By identifying water seepage as the sole critical vulnerability, the ASI can implement a surgical conservation strategy that preserves the original masonry while extending the life of the ancient irrigation system.
