It was constructed as a drought-relief project to provide irrigation water to the parched regions of Kanyakumari district.
The structure channels water across the Parazhiyar River valley via the Pattanamkal Canal.
It utilizes 28 reinforced concrete pillars to span the valley floor.
The aqueduct is part of a larger irrigation network that connects to the Pechiparai Dam.
The engineering design is specifically adapted to facilitate the flow of water across varying elevations.
Mathoor Aqueduct is one of the tallest and longest concrete trough bridges in South Asia, measuring 384 meters in length and 115 feet in height. Built in 1966 across the Pahrali River, it serves as a canal carrying water for irrigation from the Pechiparai Dam to the Vilavancode and Kalkulam taluks. The structure is supported by 28 massive concrete pillars. A concrete walkway atop the aqueduct provides views of the surrounding hilly terrain and the river valley below. The water-bearing trough is approximately 7 feet wide and 7.5 feet deep. It remains a functional civil engineering project integrated into the local agricultural water management system.
From the ground level near the base of the pillars to capture the full scale of the vertical supports.
Wear comfortable, non-slip footwear as the walkway can be slick if moisture is present.
Bring a hat and sunglasses, as there is minimal shade along the top of the aqueduct.
Carry drinking water, as facilities directly at the site are limited.
Attempting to walk on the narrow edges outside the designated path, which can be dangerous.
Maintain decorum; do not throw litter into the water channel or the valley below.
