Bangkok accelerates flood drainage in Lat Krabang and Saphan Sung

The Bangkok Metropolitan Administration (BMA) has deployed additional pumps and high-flow drainage pipes at Rom Klao Housing Community in Lat Krabang as it steps up efforts to clear floodwater from eastern Bangkok.

Bangkok Governor Chadchart Sittipunt reported at 7.30am on Friday (October 2) that no further rain had fallen. Rain on Thursday afternoon was concentrated mainly on the Thon Buri side of the capital, where about 90 millimetres of rain was recorded, while flood-hit areas received around 30mm, which had little additional impact on water levels.

Main roads reopen as floodwater recedes

Overall conditions have improved, with most main roads now passable. Standing water remains in some sois and communities, however, and the BMA is continuing efforts to drain eastern Bangkok, particularly Lat Krabang and Rom Klao Housing Community, through Prawet Burirom Canal.

High-flow pipes deployed at Rom Klao

At Rom Klao Housing Community, a large residential area in Lat Krabang, the BMA has installed pumps and high-flow drainage pipes designed to accelerate water removal.

Crews are also reinforcing gaps in flood barriers to prevent water from flowing back into the community and improve pumping efficiency. Water is being drawn from the affected area into Canal One before being pumped onwards to Prawet Burirom Canal.

The BMA's immediate priority is to lower water levels in Prawet Burirom Canal to increase its capacity to receive water from Lat Krabang and other parts of eastern Bangkok, while pumping continues at Rom Klao and surrounding communities.

Chadchart identified the main task on Friday as accelerating drainage from Prawet Burirom Canal to create additional capacity for water from Lat Krabang and the wider eastern part of Bangkok.

The BMA is also continuing to pump water from Rom Klao Housing Community and surrounding areas while working to restore Saphan Sung and other affected eastern districts to normal conditions as quickly as possible.

Conditions improve in Saphan Sung and Bang Kapi

Flooding has eased at several locations along Ramkhamhaeng Road in Saphan Sung district, including near the Revenue Office, Sammakorn Village, Bua Khao Village, Perfect Place and Nakkila Village.

Some standing water remains on Rat Phatthana Road, which connects Ramkhamhaeng Road with Rom Klao Housing Community. The BMA is increasing drainage capacity there as it works to restore normal access.

At Khlong Chan Housing Community in Bang Kapi district, where high-flow drainage pipes had previously been deployed, water has receded enough for the ground to become visible after the drainage system was adjusted to suit local conditions.

Nawamin Road has also seen a marked improvement after the BMA accelerated the transfer of water from Phang Phuai Canal into Saen Saep Canal, allowing levels to fall steadily.

Water releases monitored in Lat Phrao and Bang Bua

The BMA explained that higher water levels in Lat Phrao and Bang Bua on Thursday resulted from opening the Canal 2 floodgate further to help drain water from Pathum Thani province. Water releases are being managed gradually while levels are closely monitored to limit the impact on canal-side communities.

Roads and areas showing improvement

Areas and main roads where conditions have improved and traffic can pass include:

• Khlong Chan Housing Community
• Chaloem Phrakiat Rama IX Road
• Setthasiri area
• Suwinthawong Road, from Min Buri Prison to Nimit Mai intersection

Extra pumps deployed to affected communities

Additional pumps were deployed at Sahakorn Village on Friday morning to improve drainage capacity.

Deputy Bangkok Governor Wisanu Subsompon visited Suan Son Village on Thursday to monitor conditions, coordinate response measures and identify ways to improve drainage in the area.

The BMA continues to deploy officials, pumps and machinery to affected communities, with priority given to residents requiring assistance.

Flood assistance available through BMA hotline

People affected by flooding or needing help, particularly patients, older people and those with limited mobility, can contact the BMA hotline on 1555 or use LINE at @TraffyFondue so officials can assess the situation and provide assistance.

The BMA also thanked government agencies, the military, city officials, the private sector and local residents for contributing personnel, equipment and information to support drainage operations and relief efforts for flood-affected communities.
