Black, Foul-Smelling Water Flows From Outlet Into Nha Trang Sea

Black, foul-smelling water is continuously discharging from the Hon Mot outlet on Pham Van Dong Street into Nha Trang Bay, according to local reports. Residents have complained about the persistent pollution, which is particularly noticeable during low tide when a dark stain spreads along the coast, contrasting sharply with the surrounding seawater. The unpleasant odor associated with domestic wastewater is a constant concern for those living and visiting the area. This is not the first time wastewater discharge has been reported along Pham Van Dong Street; similar issues affecting tourism were highlighted in early March 2026. A local government representative confirmed that four outlets along the street are releasing domestic wastewater, with Hon Mot being a significant point of concern. The Hon Mot outlet, comprising two 1.5-meter diameter pipes, collects drainage from an area of approximately 12.6 hectares. The existing drainage system has not been fully developed to separate domestic wastewater from rainwater, leading to the discharge of stagnant, polluting water directly into the sea. To address this, the Khanh Hoa provincial authorities are undertaking a project to treat wastewater sources in Nha Trang. The plan includes constructing a wastewater separation well, a pumping station, and a new collection system at the Hon Mot outlet to minimize direct discharge into the sea. The People's Committee of Nha Trang City is also intensifying checks for illegal connections to the rainwater drainage system and inspecting businesses, restaurants, and hotels for violations.
