The disaster zones were announced at a press conference jointly held by BMA deputy governor Tavida Kamolvej, BMA city clerk Khachit Chatwanit, and BMA spokesman Ekwaranyu Amrapan.
The six subdistricts are: Lat Krabang subdistrict, Klong Song Ton Noon, Klong Sam Prawet, Khum Thong, Thap Yao and Lam Pla Thiew.
A total of 10,300 households with 20,767 residents were affected by the floods that also caused damage to 800 rai (128 hectares) of paddy rice fields, 22 rai (3.5 hectares) of fruit orchards and 500 rai (80 hectares) of fish ponds.
Khachit told the press conference that Bangkok was experiencing severe flooding in many parts because the capital had been hit by 100 million cubic metres of rainwater during the past two weeks.
He said the affected areas were two groups.
Khachit said the floodwaters in nearly all sois in Bang Khen had almost dried up. If there are no rains for a few days, the situation would return to normal, he added.
In the second group, Lat Krabang, Prawet, and Nong Chok districts were affected.
Khachit said the canals’ levels in the three districts had gone down by 50 centimetres and the situation was improving.
The city clerk said the Bangkok governor had also sought help from the prime minister to instruct the National Water Resources Office to coordinate for draining flood water from eastern Bangkok to Paed Riew district in Chachoengsao province.
Khachit added that the BMA governor has ordered the opening of Lat Krabang and Wat Krathum Sua Pla sluice gates so the water level was dropping fast and the floodwater would be drained within seven days provided there were no more rains.
He added that the water from upstream provinces through Bang Sai district could still be handled by the embankment along the Chao Phraya River. But the areas in 17 districts outside the embankments would be monitored by respective district offices, Khachit said.
She said the BMA has prepared mobile toilets, medicines and bags of necessities to help people in flooded areas.
She added that the declaration of disaster zones was not aimed at causing panic but at speeding up assistance to flood victims.
Tavida said the BMA has been closely cooperating with Disaster Prevention and Mitigation for over two weeks but the visit by the interior minister to Lat Krabang on Wednesday was to show that all sectors would help Bangkok deal with the flood situation.
Ekwaranyu said the BMA has been severely criticised for perceived inaction or little action during the crisis, especially the Lat Krabang flood.
So, the BMA has to explain that it has been dealing with floods in the capital all the time and would use all means to mitigate the people’s grievances.
