Several wastewater treatment projects are expected to be partially put into operation in Da Nang City, central Vietnam this year to stop untreated wastewater mixed with rainwater from flowing onto local beaches on rainy days.
Among the projects, a drainage system has been built along coastal residential areas since 2019 to collect both wastewater and rainwater, preventing them from pouring into the sea, according to the city’s Department of Construction.
In the My Khe-My An area, where the world’s eighth most beautiful beach as voted by readers of the travel site Tripadvisor is located, the construction of another trial system is underway to separate the collection of wastewater from rainwater.
Currently, sewage from households is gathered via a classification well before running to the city’s wastewater treatment plants.

However, domestic wastewater is often mixed with rainwater and overflows into local beaches on rainy days, when streams of black, foul wastewater can be spotted flowing toward the sea through many seaside drainage gates.
There are 15 drainage gates leading to the sea in Son Tra and Ngu Hanh Son Districts and 31 others are situated in Hai Chau, Lien Chieu, and Thanh Khe Districts.
The undesirable discharge of wastewater, often mixed with rainwater, through those drainage gates have marred the environment of Da Nang, which is dubbed the most liveable city in Vietnam and is famous for beach travel.
Secretary of the Party Committee of Da Nang Nguyen Van Quang said during a recent inspection of the aforementioned drainage system projects that some of their components are projected for completion within this year to help put an end to the overflow of wastewater into the sea.
