Prime Minister Sheikh Hasina has called on the wealthy to stand by the flood-affected people.
"I expect that the well-off people will come to aid the victims," she said during an event on Thursday at her office.
The second spell of floods this year has affected nearly 7.5 million people, according to figures by the National Disaster Response Coordination Centre or NDRCC.
As many as 132 people died in the last two weeks.
Floodwaters have destroyed communities in 32 districts out of the 64 across the country.
Many have become destitute because rivers overflew.
The government is giving support to all those affected by the floods, she said.
Crops on 10,583 hectares of land have been totally washed away while another 600,587 hectares of farmlands have been partially damaged;
“We are trying to build homes for those who have lost their belongings, resettle the people who have lost their land, tried to ensure people can return to working the land as soon as the waters recede. We are sending support and aid,” said Hasina, according to bdnews24.com.
