The Ho Chi Minh City Transport Department must eliminate all areas vulnerable to inundation within the next year, the city People’s Committee Vice Chairman, Nguyen Huu Tin, directed Tuesday.

 

Chien Luoc Street in Binh Tri Dong A Ward, Binh Tan District, Ho Chi Minh City is seen serious flooded on October 21, 2014, the third day of inundation in a row.

 

The vice chairman gave the order at a meeting with the transport department and other relevant agencies to discuss urgent solutions to the city’s ongoing flooding issues.

“No matter what you say, all of the flood-prone areas must be eliminated next year,” Tin said, in response to the difference in the numbers of such areas reported by the department and the Anti-Flooding Program Operation Center.

The department raised the number to 27, while the center affirmed that the figure is only 11.The city has 58 flooded areas in 2011, a figure that was recently reduced to 11 and will be completely eliminated in 2015, said Nguyen Hoang Anh Dung, deputy director of the center.

Meanwhile, Le Hoang Minh, deputy director of the transport department, said that besides the above 11 flooded areas, 14 areas that received anti-flood projects have become prone to flooding again.

Recently, two more areas have been added to the list of flood-prone areas, bringing the total number of such areas to 27.Regarding the 14 areas that have relapsed, ten have been affected by the ongoing Tan Hoa-Lo Gom water drainage project, Dung saidMeanwhile, Minh said only five areas are affected by the project, and the remaining nine, mainly in Binh Thanh District, become prone to flooding again due to reduced drainage capacity of the sewers there.  

The sewers used in these nine areas cannot handle rainfall of over 100 mm, Minh said.He added that all the other sewers in the city’s central area use the same type of systems, which were determined in the city’s overall drain plan (Plan 752) approved by the Government in 2001.

Solutions

Regarding solutions to combat flooding, Luong Minh Phuc, head of the HCMC Urban Traffic Works Investment Management Board, suggested a plan to build an embankment system along the city’s canals at a height of 1.32 meters according to Plan 752 to retain water flowing from sewers.

He also proposed  the construction of large pipelines beneath the existing sewers to store water in case of heavy rains.In addition, regulating reservoirs should be built to ease the inundation, he added.

The vice mayor said these solutions are long-term ones that could take 5-10 years to implement, while the city needs immediate measures for all of the flood-prone areas.

Tin argued that there is no space in the city’s central area for regulating reservoirs.

“The transport department is a think tank for the city People’s Committee in terms of anti-flooding proposals, but the department has yet to suggest any solutions so far,” Tin critiqued.

“The department now procrastinates when asked about solutions,” he added.The vise major gave the department 10 days to submit to city authorities a plan to open a seminar on anti-flooding with the participation of local and foreign scientists and experts in the field to seek direct and immediate solutions to eliminate all flooded areas.

More pumps can be mobilized to drain water to canals, Tin suggested.

He also directed the department and the Planning and Architecture Department to conduct surveys on building two regulating reservoirs in the Khanh Hoi area of District 4 and Thu Thiem in District 2.Two more regulating reservoirs may be built later in Thu Duc and Binh Chanh Districts, he added.
