Over recent years, a large volume of wastewater from the drainage systems along Da Nang’s coastal streets has been discharged directly into the sea.  This has adversely affected the nearby beaches, the aesthetics of the local urban landscape, and the development of the local beach tourism sector.

Wastewater being discharged into the sea from a local drain …

The main reasons seem to be that domestic effluent from residential areas is being discharged directly into the city’s drainage system with a large amount of organic and inorganic pollutants.  These pollutants remain in the drainage system for a long time before running into the city’s dedicated wastewater treatment plants, thereby causing bad smells.

The wastewater is found to overflow the Le Do sluice gate in the basin of the Phu Loc River and this results in severe environmental pollution in Da Nang Bay along Nguyen Tat Thanh.  The overflow is being caused by the ineffective operation of the sluice gate’s pumping station because it is frequently filled with sand.  In addition, no wastewater collection systems have been built along Tran Dinh Tri and Xuan Thieu coastal streets.

… causing environmental pollution

In addition, untreated wastewater from drainage systems along coastal areas in Ngu Hanh Son and Son Tra districts is overflowing into the sea, causing strong odours nearby.  The reason is that the pumping systems at the SPS1, SPS2, SPS3, SPS4 and SPS5 stations have deteriorated, and the rising number of luxury seaside resorts and hotels along the coast has resulted in a significant increase in the volume of wastewater.

In attempting to effectively resolve the current environmental pollution hotspots, the city’s Water Drainage and Wastewater Treatment Company (DWTC) will dredge the sand and sludge and clear any garbage in wastewater collection ditches and sluice-gates in order to try to reduce the environmental pollution.

A focus will be on replacing the downgraded wastewater pumps with new ones, and building more dedicated wastewater collection plants.
