Out today, the first instalment of our three-part series on sand mining in tamil nadu.
Stepping onto the bank, the first thing that’s visible is a ten-wheeled tipper. It grinds to a halt at the end of a queue of similar trucks. Beyond it stretches a vast riverbed. That is the Thenpennaiyar, one of the larger rivers in central Tamil Nadu. It is summer and there isn’t a drop of water in the river. The riverbed, with its carpet of sand, is warming under the sun. It looks like it has been ploughed by a giant tractor. Long trenches are separated by ridges that are wide enough to serve as roads for the tippers. All along the monochrome riverbed are queues of trucks. At the head of each queue is an excavator. The arm of the machine dips into a trench, pulls out a shovelful of sand and pours it into the tipper waiting alongside. As the tipper fills up, it moves away, and another tipper takes its place.
It’s hard to tell how far this sand quarry stretches. The trenches are as deep as seven metres. The ridges are all that is left of the original riverbed. A scab of dark earth is visible at the bottom of one trench. So much sand has been scraped away that the Thenpennaiyar’s clay base stands exposed. According to locals, anywhere between 2,500-3,000 tipper-loads of sand leave from here each day. With each tipper designed to carry 20 tons, that’s 50,000 tons of sand a day. This quarry in Villupuram district, about an hour from Pondicherry, is a good introduction to the daunting scale of sand mining in Tamil Nadu. The Thenpennaiyar enters this part of northern Tamil Nadu from Karnataka and flows through the district for about 100 kilometres before entering the neighbouring district of Cuddalore. In this stretch, said locals, there are two more quarries of similar size. And that’s just one river in one district.
