Flash Flood Hits NEEPCO Project Area

The sudden flooding caused widespread inundation in low-lying areas and damaged residential quarters associated with the NEEPCO project. As a result, authorities launched emergency response measures to assist affected residents and assess the extent of the damage.
Retaining Wall Collapse Triggered Flooding
According to information provided by the State Disaster Management Department, the flooding occurred after an under-construction retaining wall collapsed during heavy rainfall.
Consequently, large volumes of water entered nearby residential quarters and surrounding areas. Officials stated that the incident significantly affected housing facilities located close to the project site.
Furthermore, authorities continue to evaluate the structural impact of the flood and monitor conditions in the affected zone.
More Than 15 Residential Quarters Damaged
Initial assessments indicate that more than 15 residential quarters sustained damage due to the flash flood.
