BMA gears up to fight floods during rainy season

BMA’s Drainage and Sewerage Department is fully prepared with facilities and teams to prevent and tackle flooding in Bangkok this rainy season.

The Bangkok Metropolitan Administration’s Drainage and Sewerage Department announced on Wednesday that it has fully prepared measures to prevent or mitigate flooding in the capital during this rainy season.

Jessada Chantharaprapha, Director of the Drainage and Sewerage Department, said his department has taken all necessary steps in line with this year’s operation plan to prevent and reduce flooding.

The Meteorological Department has announced that the rainy season began on May 15.

According to Jessada, his department has prepared the following facilities to drain rainwater:


4 flood tunnels
200 pumping stations
243 water gates
349 ponds for draining water from sewers
Lowered water levels in monkey-cheek ponds to retain rainwater


He added that the department has also prepared officials to handle flooding by:


Assigning staff to man flood tunnels, pumping stations, and pumping ponds around the clock
Preparing rapid-deployment teams to manage flooded areas after heavy rainfall
Assigning officials to monitor and drain water from risk areas, including traffic underpasses




Jessada also noted that his department has removed garbage from the fronts of sewers and pumping stations, and cleared weeds in canals to ensure faster drainage.

Additionally, all necessary equipment, including mobile water pumps and power generators, has been readied for deployment to flooded areas.



The 50 district offices have been instructed to set up flood mitigation operation centres to provide timely assistance to flood victims.

Jessada said the BMA will keep Bangkokians informed of flood situations in real time through various communication channels.

In the event of flooding, residents can alert the BMA for assistance via the Traffy Fondue app or through the BMA website at dds.bangkok.go.th.
