Hanoi endured two serious urban flooding times just in one week due to heavy rain. It is understandable that torrential rain normally creates temporary flooding, yet such a serious situation as that in Hanoi is attributed to over-urbanization. It is high time detailed planning was strictly observed to tackle the problem.
The People’s Committee of HCMC has proposed the ministries of Finance, and Planning and Investment to consider a construction project of a drainage system and wastewater management works in the West of HCMC to adapt to climate change, said the Committee Office on April 8.
River erosion and high tide have made great impact on dwellers’ lives and production; accordingly, Ho Chi Minh City authorities have drawn up embankment construction projects to regulate water level and drainage. However, many of them are on paper.
Vietnam’s drainage and wastewater treatment system has been old, downgraded, asynchronous and unable to catch up with urbanization speed, said Mr. Cao Lai Quang, chairman of Vietnam Water Supply and Sewerage Association.
The rainy season has just started but many areas in HCMC have been heavily flooded after rains with precipitation not being large. Notably, flooding has occurred in streets with fully invested drainage systems.
