The latest water situation shows sea levels beginning to fall, with 37 pumps operating from 8 stations to push water out to sea. Meanwhile, the Department of Disaster Prevention and Mitigation (DDPM) warns residents in three districts of Samut Prakan to remain vigilant despite stable water levels.
On 30 September 2026, flood conditions in Samut Prakan Province prompted officials to accelerate water drainage as sea levels began to drop, providing an opportunity to push water from various canals out to the sea. The critical period for drainage was from about 11:40 a.m. to 3:30 p.m. Meanwhile, many inner canals remained at full capacity, and the province still had to handle water discharged from Bangkok.
Today, the highest tide reached 3.60 meters at 07:48 a.m. before receding. It is expected that by 6:26 p.m., the sea level will be around 3.20 meters, allowing officials to use the ebb tide to continuously accelerate water drainage from the area.
Currently, various inner canals in the province remain at high and full capacity, while coastal canals have begun to slightly decrease but still need to receive water from the inner canals continuously. Additionally, water from the eastern part of Bangkok must be discharged through Samut Prakan toward the sea, causing water levels in some areas to remain stable or occasionally rise according to the timing of drainage from Bangkok.
For drainage, officials are operating a total of 37 pumps from 8 stations at full capacity to remove water from the area. These stations include Phra Ya Wisut, Nang Hong, Charoen Rat, Tamru, Bang Pla, Bang Pla Ra, Suvarnabhumi, and Khlong Dan 2, with a combined pumping capacity reported at 233 cubic meters per second.
Meanwhile, at around 11:20 a.m., the Department of Disaster Prevention and Mitigation (DDPM) issued a warning to residents in Bang Phli, Bang Bo, and Bang Sao Thong districts after some water was discharged from eastern Bangkok toward the sea. This caused water levels in the area to remain stable or slightly decrease, but continuous monitoring of the situation is still necessary.
Officials have urged residents in risk areas to closely monitor water levels, especially during periods of drainage from Bangkok. They also advised increased caution in using electricity in flooded zones due to potential electrical leakage risks that could be life-threatening.
It is expected that starting today, rainfall in the area will significantly decrease. If no additional rain occurs, water volumes are likely to gradually decline. However, close monitoring of water inflow from Bangkok and sea levels remains essential.
