The units have sunk open wells on the Amaravathy riverbed; the activity has been going on unchecked

Many dyeing units in Karur have been illegally siphoning off groundwater from the parched Amaravathy riverbed. The unlawful activity has been going on unchecked under the very nose of the officials. Scores of dyeing units are situated at Sellandipalayam, Sukkaliyur and Rayanur on the southern banks of the river in Karur. Though a ban is in place on operating dyeing units without zero liquid discharge systems, many units are operating on the sly. The officials have taken token action against some units but many continue to operate unimpeded in the region.
