These pumps can handle 123 million cubic metres of water every day.
“On the western side, there are 336 pumps that have the capacity to handle 80 million cubic metres,” the department’s director-general Chalit Damrongsak said yesterday.
In Bangkok’s eastern zone, there are 324 pumps that have a total capacity to handle 43 million cubic metres of water each day.
Chalit said water drainage depended on many factors, including sea levels.
He added that pumps would also be used to drain floods out of Nakhon Sawan and Ayutthaya.
