Hyderabad, Sep 27 (NationPress) Passengers at the Mahatma Gandhi Bus Station (MGBS) in Hyderabad were rescued by teams from the Disaster Response Force as the Musi River overflowed, flooding the largest bus station in Telangana.
A significant surge in the floodwaters after midnight, caused by substantial releases from the twin reservoirs of Himayat Sagar and Osman Sagar since Friday, led to the submersion of both bridges located within the MGBS area, trapping numerous passengers.
As water from the swollen river breached the platforms of the extensive facility, authorities were compelled to suspend bus services and initiate rescue operations for those trapped.
Rescue teams from the Hyderabad Disaster Response and Asset Protection Agency (HYDRAA), the Greater Hyderabad Municipal Corporation (GHMC), alongside the Police and Fire Services Department, worked diligently to evacuate the stranded passengers.
Chief Minister A. Revanth Reddy instructed officials to ensure the safe evacuation of those caught in the flood.
Meanwhile, the Telangana State Road Transport Corporation (TSRTC) rerouted buses heading to MGBS from various locations in Telangana and Andhra Pradesh to alternative destinations within the city.
Officials described the situation at MGBS as unprecedented, given that it is recognized as one of the largest bus terminals in Asia.
The Musi River, which traverses the city, was flowing perilously, inundating portions of nearby residential areas. Approximately 1,000 people from Shankar Nagar, Vinayaka Veedhi, Moosa Nagar, Padma Nagar, and other localities in Chaderghat were evacuated to relief camps.
The Chaderghat causeway was completely submerged, with water overflowing the old bridge at Moosarambagh, which was already closed to traffic. Additionally, a new high-level bridge under construction sustained damage due to the flooding, with iron rods and construction materials being swept away. Water also infiltrated homes in the Ambedkar Nagar area adjacent to the bridge.
Following intense rainfall in recent days, the reservoirs of Osman Sagar and Himayat Sagar on the outskirts of the city experienced heavy inflows. Authorities opened 24 gates to release floodwater downstream, with discharge rates escalating to 35,000 cusecs late Friday night, triggering the floods.
Officials noted that the Musi had not witnessed such flood levels in recent history. With rain continuing in upstream areas, the water level is expected to rise further.
The catastrophic floods in the Musi River of 1908 claimed approximately 15,000 lives, significantly altering the landscape of Hyderabad. In response, Mir Osman Ali Khan, the then Nizam of Hyderabad State, engaged engineer M. Visvesvaraya to construct the Osman Sagar and Himayat Sagar reservoirs upstream to mitigate future flooding.
