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.

Additionally, HCMC has had seven landslides in suburban districts 2, Can Gio, and Nha Be damaging total two houses and partially two others.

Also in 2018, the Steering Board for Natural Disaster Prevention and Rescue said that the city has tackled seven flooded streets including Me Coc, Luu Huu Phuoc in district 8, Luong Dinh Cua and Truong Vinh Ky in district 2 and Ton That Hiep, An Duong Vuong, and Ho Van Tu.

In order to solve the flooding and draining, HCMC has intensified the speed of its overall drainage system and irrigation system.

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.

At present, the city is implementing the first phase of the project to tackle flood due to high tide with consideration of climate change. The project is carried out in the area of 570 square kilometer for approximately 6.5 million population.
