Many embankment projects still on paper as HCMC battles severe flooding
In 2018, HCMC experienced seven high tide. For instance, the high tide in early February, water level in Phu An station was 1.71 meter exceeding the third-stage warning level.

However, the sewerage system has been designed with rainfall of 92 mm and water level of 1,32 meter whereas the new design has included climate change and high rainfall.
According to the municipal Department of Agriculture and Rural Development, the new design is divided into three sections comprising of the right area of Sai Gon - Nha Be river and the left area of Vam Co - Vam Co Dong river; the intersection in the left area of Sai Gon – Dong Nai river and the left area of Nha Be- Soai Rap river.
