Widespread flooding has submerged large parts of Satkania and Lohagara upazilas in South Chattogram following continuous rainfall that began on July 6, 2026. Environmental experts say the disaster is not only due to heavy rain but also decades of unregulated hill cutting, illegal brick kilns, and unplanned development that have reduced the region’s natural water retention capacity. Around 300,000 people are reportedly trapped by floodwaters, with homes, schools, and roads inundated and communication severely disrupted.

Investigations reveal that soil from hill cutting in Satkania’s Aochia area is being supplied to illegal brick kilns in nearby Banshkhali. Despite legal actions, influential kiln owners have largely avoided prosecution. The Department of Environment acknowledges limited manpower and legal constraints in controlling the destruction, with over 300 unlicensed brick kilns operating across Chattogram. Officials say daily raids continue but public awareness remains low.

Experts warn that ongoing hill cutting and land filling will worsen flash floods and waterlogging. They also caution that the new Dohazari–Cox’s Bazar railway, if not properly designed with adequate culverts, could act as an artificial barrier to water flow.
