Untreated textile effluents allegedly discharged into Sunnambu Odai in Erode

Residents of Erode allege untreated textile effluents are contaminating Sunnambu Odai, threatening public health and agriculture.

Residents of Vairapalayam have alleged that untreated effluents from textile processing units continue to be discharged into Sunnambu Odai, which eventually merges with River Cauvery, raising serious concerns over public health and agricultural sustainability.

According to residents, the drain, originally designated to carry household sewage, is frequently misused for releasing industrial effluents. They claim that the discharge is not restricted to late-night hours, as is often alleged in such cases, but occurs openly during the daytime as well. “We can see the change in the colour of the water and a strong, unpleasant odour spreading across the area,” a resident said.

Locals further alleged that the drain carries toxic chemicals and hazardous substances from textile units, which ultimately mix with the river water. The Cauvery serves as a lifeline for irrigation in delta districts and is also a crucial source of drinking water supply for several parts of the State. Any contamination, residents fear, could have far-reaching consequences.

Apart from Sunnambu Odai, effluents and domestic sewage are reportedly discharged into Perumpallam, Pichaikaranpallam and other drainage channels that flow into the river system.

On March 13, 2024, Chief Minister M. K. Stalin had announced the establishment of sewage treatment plants within the Corporation limits to treat wastewater before its release into waterbodies. However, residents said the project is yet to take off, while pollution continues unabated, causing anxiety among residents and farmers.
