Authorities in Ho Chi Minh City are planning a VND360 billion (US$15.92 million) project to upgrade one of the main canals to help prevent Vietnam's biggest airport Tan Son Nhat from being flooded during torrential downpours.
In its recent proposal, Tan Binh District, where the airport is located, said upgrading the 745-meter long canal will solve the flooding issue that once threatened to shut down the airport, news website VnExpress said on Thursday.
The Japanese canal, as it is officially known, together with many others, have been reportedly blocked by waste and houses illegally built near the airport.
The Vietnamese aviation authority first warned of flooding risks at Tan Son Nhat, which handles an average of 630 flights a day, in 2013.
Last year the airport was hit by severe flooding in August and then in October when some of its areas were up to 20 centimeters under water and the power station of its traffic control tower was at risk of being shut down.
