Mathur Aqueduct or Mathur Hanging Trough, is an Aqueduct in Southern India, in Kanyakumari District of Tamil Nadu state. Built over the Pahrali River (also called Parazhiyar), it takes its name from Mathur, a hamlet near the Aqueduct, which is at a distance of about 3 kilometres from Thiruvattar town and about 60 km from Kanyakumari, the southernmost town of India. It is one of the longest and highest aqueducts in South Asia and is also a popular tourist spot in Kanyakumari District. The nearest railway station is Kullithurai Railway Station which is about 15 kilometres and the nearest airport is the Trivandrum International Airport which is about 70 kilometres.
Mathur Aqueduct was constructed in 1966 by the late Chief Minister of Tamil Nadu, K. Kamaraj, as a drought relief measure across the river Pahrali. Its purpose is to carry water for irrigation from an elevated level of one hill to another. The irrigation water feeds the taluks of Vilavancode and Kalkulam.
The Aqueduct is built across the Pahrali river, a small river that originates in the Mahendragiri Hills of the Western Ghats. Mathur Aqueduct itself carries water of the Pattanamkal canal for irrigation over the Pahrali river, from one hill to another, for a distance of close to one kilometer. This Aqueduct is necessitated due to the undulating land terrain of the area, which is also adjacent to the hills of the Western Ghats.
Mathur Aqueduct is a concrete structure held up by 28 huge pillars, the maximum height of the pillars reaching 115 ft. The trough structure is 7 ft in height, with a width of 7.5 ft. The trough is partly covered on top with concrete slabs, allowing people to walk on the bridge and also see the water going through the trough. Some of the pillars are set in rocks of the Pahrali river, though some of the pillars are set in hills on either side.
Road access allows one to drive in to one side of the Aqueduct (up to one end), while it is also possible to drive into the foot of the Aqueduct (the level where the Pahrali flows) on the opposite side. There is also a huge flight of stairs (made in recent times) that allows one to climb from the level of the Pahrali river to the trough.
Irrigation Water flows through the trough for a major part of the year, except in the summer (from February to May).
In recent times, Mathur Aqueduct has become a popular tourist attraction in Kanyakumari District. The tourism department and the local Panchyat office have improved facilities for the visiting tourists.
