Rubbish collected from Sai Mai, Thawee Watthana, Nong Khaem, Don Muang and Bang Khae districts is less than half of the usual amount.
Since the runoff raged into the capital, garbage trucks have been unable to make their rounds in many heavily flooded zones and mounting piles of garbage have further polluted the flood water.
To treat the water, effective micro-organism balls and liquid have been mixed in and the Bangkok Metropolitan Administration has recruited 915 volunteers to rake the refuse out of the flooded zones.
“We’re trying to collect as much garbage as possible and we’re trying to do it as fast as possible,” BMA spokesman Wasan Meewong said.
The waste problem would get worse after flood victims return to their homes and throw out damaged stuff.
Flood waters have continued to recede in many parts of Bangkok and the levels of the Mon, Bangkok Yai and Lat Phrao canals have continued to drop.
The swamp on Vibhavadi-Rangsit Road has also subsided by 20 centimetres, so officials have removed the flood barriers and big pumps from in front of the Energy Complex, which houses the government’s Flood Relief Operations Centre.
However, as the flooding is dragging on in many districts, the BMA’s shelters still accommodate 15,204 flood refugees.
