Kerala survey uncovers nearly 720 illegal sewage discharge points

A comprehensive survey conducted across four districts in Kerala has revealed an alarming scale of water pollution from untreated sewage discharge. The investigation identified nearly 720 illegal outlets releasing untreated sewage directly into natural water bodies and streams, posing significant environmental and public health risks.

The contamination pathway involves 39 public drains that connect to various water sources across the surveyed districts. These drains channel untreated sewage from residential and commercial areas without any processing or treatment, allowing hazardous waste to flow directly into rivers, streams and other water bodies that communities depend upon.

The findings underscore the gap between existing infrastructure capacity and the volume of sewage generated in these regions. Many municipalities and local bodies lack adequate treatment facilities, forcing them to rely on drainage systems that bypass proper sewage treatment plants entirely.

The scale of illegal discharge outlets suggests a systemic failure in water management and environmental protection mechanisms. Environmental experts have flagged the discharge as a critical threat to aquatic ecosystems and drinking water sources, particularly in areas downstream of these contamination points.

The survey results are expected to prompt authorities to undertake corrective measures, including infrastructure upgrades, enforcement of environmental regulations, and possible prosecution of unauthorised discharge operators. Water quality testing and comprehensive mapping of all discharge points are being recommended as immediate action items.
