Residents of Vairapalayam, a residential locality in Tamil Nadu’s Erode, have alleged that untreated effluents from textile processing units are continuing to flow into Sunnambu Odai, a key water channel that ultimately merges with the Cauvery, prompting concerns over public health and agricultural sustainability.
According to local residents, the drain was originally designated to carry domestic sewage but is frequently misused for the discharge of industrial effluents. They have claimed that the release of waste is not confined to late-night hours, as is commonly alleged in such instances, but also takes place openly during the day.
A resident stated that there had been a visible change in the colour of the water, accompanied by a strong and unpleasant odour spreading across the area. Locals further alleged that the drain carries toxic chemicals and hazardous substances from textile units, which eventually mix with the river water.
The Cauvery serves as a vital source of irrigation for delta districts and is a crucial supplier of drinking water to several parts of the State. Residents expressed fears that any contamination of the river could have far-reaching consequences for both farming communities and urban populations dependent on it.
Apart from Sunnambu Odai, residents have alleged that effluents and domestic sewage are also being discharged into Perumpallam, Pichaikaranpallam and other drainage channels that feed into the river system.
On 13th March 2024, Chief Minister M. K. Stalin announced the establishment of sewage treatment plants within Corporation limits to ensure that wastewater is treated before being released into waterbodies. However, residents have stated that the project has yet to be implemented, while pollution continues unchecked, causing growing anxiety among local residents and farmers.
