Authorities in Kolkata are moving to modernize river rescue operations along the Ganga by introducing a specialized underwater communication system designed to improve coordination between divers and rescue teams during emergencies. The decision follows field assessments that revealed significant limitations in drone-based surveillance due to the river’s extremely low underwater visibility.Authorities in Kolkata are moving to modernize river rescue operations along the Ganga by introducing a specialize underwater communication system designed to improve coordination between divers and rescue teams during emergencies.

Authorities in Kolkata are moving to modernize river rescue operations along the Ganga by introducing a specialized underwater communication system designed to improve coordination between divers and rescue teams during emergencies. The decision follows field assessments that revealed significant limitations in drone-based surveillance due to the river’s extremely low underwater visibility.The proposed underwater communication system will enable divers to remain connected with each other and with surface teams throughout search missions.
The equipment is designed to function even when divers are wearing full protective gear and face masks, ensuring that instructions, warnings, and discoveries can be relayed immediately during operations.Urban emergency planners say communication is often the most crucial factor in underwater rescue work, particularly in rivers like the Ganga where strong currents, suspended sediment, and debris reduce visibility to almost zero. In such environments, divers frequently rely on tactile navigation rather than sight, making constant contact with support teams essential for safety.The communication technology will incorporate waterproof audio devices linked to a surface control unit through specialized cables or signalling lines. Noise filtering mechanisms are also expected to minimize disturbances caused by water turbulence, bubbles, or equipment movement, allowing divers to exchange instructions more clearly during complex operations.Alongside the communication upgrade, Kolkata’s disaster response units are undergoing a broader equipment modernization programme aimed at strengthening river safety infrastructure. Officials say the city is investing in advanced diving gear that allows rescuers to remain underwater for longer duration while maintaining safe breathing conditions.Additional support equipment is also being added to the response fleet, including inflatable rescue boats, paddle craft, floating safety rings, and protective gear for emergency teams. Specialized underwater cutting tools are being introduced to help responders access submerged vehicles or boats during accident investigations or rescue missions. Urban safety experts say these upgrades are increasingly necessary as Indian cities expand along riverbanks and waterfronts. Kolkata’s river corridor remains one of the busiest stretches of the Ganga, supporting passenger ferries, cargo movement, religious gatherings, and recreational activities.As riverfront redevelopment projects continue to reshape urban waterfronts across India, disaster preparedness systems are becoming an essential component of resilient city planning. Efficient rescue infrastructure not only protects lives but also strengthens public confidence in the safety of growing urban waterways.
City authorities say the introduction of the underwater communication system will significantly improve coordination during search missions, enabling faster responses in emergencies along the Ganga and other major water bodies within the metropolitan region.
