'Sankey Tank is Dying': No longer just a lake issue, say environmental groups against unscientific developments

Bengaluru's Sankey Tank is in trouble, with groups saying it's "dying" due to bad development. They held a campaign on May 24, 2026, to save it. Years of building on it, sewage, and changing its natural water flow have hurt the lake and groundwater. People want a stop to building and a check on water quality.
