Tech Desk: In the wake of devastating floods in Nepal’s Trishuli valley, a WhatsApp group comprising over 500 engineers, former hydropower workers, and government officials has become an unexpected lifeline for rescue operations. This dynamic digital network is providing crucial real-time intelligence, including detailed tunnel maps, project drawings, and vital information on missing personnel, empowering teams searching buried hydropower facilities where hundreds are feared trapped.

The catastrophic floods, triggered by a glacial and mountain collapse near the Nepal-China border on August 26, have claimed over 1,200 lives and left nearly 4,000 missing. With the terrain dramatically altered and tunnels filled with mud and debris, conventional rescue methods faced immense challenges. This is where the Nepal rescue WhatsApp group has proven indispensable, offering a unique blend of collective memory and technical expertise.

Rescuers on the ground can post urgent requests directly to the group, receiving immediate responses. For instance, an official searching the buried Chilime hydropower plant quickly obtained layout drawings and access tunnel details from a group member, dramatically accelerating their efforts. Former employees leverage their intimate knowledge of the facilities to guide teams through areas transformed by the disaster.

Crucially, the group also assists in locating missing workers by sharing names and contact details with authorities, enabling them to trace last recorded phone locations. This collaborative, rapid information exchange is proving vital in a disaster zone where the very structure of the tunnels has been compromised, turning collective digital wisdom into a powerful tool for saving lives.
