Thai PM proposes water retention zones to shield Bangkok from flooding

The initiative reflects growing concerns about Bangkok's vulnerability to seasonal flooding, which has caused significant disruption and damage to the city in recent years. Water retention areas would serve as buffer zones to absorb excess rainfall and control water movement toward residential and commercial districts.

Acording to the plan, these designated zones would be strategically positioned around the metropolitan perimeter to intercept floodwaters before they reach densely populated areas. The retention areas would function as temporary storage facilities during peak monsoon periods, releasing water gradually to prevent rapid inundation.

The proposal forms part of a broader flood management strategy for the capital region, which has struggled with recurring waterlogging episodes affecting millions of residents and businesses. Officials have indicated that the project would require coordination between multiple agencies and local administrations to identify suitable locations and implement necessary infrastructure.

The government views the water retention system as a complementary measure to existing flood defenses and drainage improvements already in place across Bangkok and surrounding provinces. Implementation timelines and budget allocations for the project have not yet been formally announced.
