Hai Phong City possesses natural features such as a low elevation, and high tide level, surrounded by rivers, so drainage is difficult.  Meanwhile, the drainage infrastructure in the city has not been synchronously invested, and can only tolerate the drainage of 50mm rains. Therefore, heavy rains often lead to urban flooding.

A new solution for this year's stormy season is the construction of a drainage monitoring and control center located at the Ba Tong pumping station, which is expected to be completed and put into use in May. By applying information technology and automation, it is possible to monitor reservoirs and tidal culverts, as well as the rainfall and some risky spots in 4 districts: Hong Bang, Ngo Quyen, Le Chan, and Hai An for a timely response.

According to the approved master plan on the surface water and wastewater drainage by 2025, with a vision to 2050, Hai Phong needs to build 32 more centralized wastewater treatment plants, 450 km of sewer lines, 174 wastewater pumping stations, and 33 rainwater pumping stations. Seeing that the infrastructure has not met the current needs, the city's drainage sector strives to build a strict process, considering accurate scenarios for each rain and storm to take timely measures, reduce floods and minimize the consequences caused by natural disasters.
