Hyderabad Water: Critically Polluted Sources Exposed

Hyderabad's drinking water supply faces a critical threat, with studies revealing severe pollution in four of its six major sources that cater to approximately 80% of the city's daily requirement. These sources, including Osmansagar, Himayatsagar, Krishna, and Godavari, are contaminated with sewage, faecal coliform, and industrial effluents, according to research published in September 2025 and March 2025.

The condition of Osmansagar is particularly alarming, exhibiting high levels of heavy metals and faecal bacteria, attributed to untreated sewage and industrial discharge. Similarly, reports from NIT Warangal highlight industrial pollution hotspots along the Krishna river, while a joint study by NEERI and IIT-Hyderabad points to untreated wastewater entering the Godavari river. These issues pose significant public health risks, potentially leading to widespread waterborne diseases.

Adding to these concerns, Hyderabad's aging pipeline network presents a substantial risk. Experts warn that frequent leakages and the proximity of water supply lines to sewerage networks increase the likelihood of cross-contamination. Despite these findings, the Hyderabad Metropolitan Water Supply and Sewerage Board assures that all pollutants are managed at treatment plants through rigorous testing and chlorination.
