This is a colorful picture taken of the stink and black arroyo Tau Hu in Ho Chi Minh City.
Walking along these canals you could experience odors emanating from polluted water that have made living condition of local residents worse.
Inside the city a hydrological network of five main arroyo systems acts as the natural water drainage: Nhieu Loc – Thi Nghe (9 km), Tau Hu – Kinh Doi – Kinh Te (19.5 km), Ben Nghe (5.9 km), Tan Hoa – Ong Buong – Lo Gom (7.2 km), and Tham Luong – Ben Cat – Vam Thuat (14 km). The total length of these canal systems is about 56 km with about 100 km from smaller tributaries. There are about 461,000 cubic meters of wastewater discharged into the receiving creek, which flow on to waterways in the residential area before eventually reaching the Saigon River. The demand from industries, businesses, and households surpassed the current supply distribution capacities. The water quality in river courses and underground sources is also highly degraded due to many sources of pollution.

This story is nothing news. The stink odor and the black water have became topic of at least 2 novels before 1975. Not until recently, local authorities have been successfully planned and enforced the removal of thousand of residences within this polluted area to several new apartment complexes in Binh Chanh District as the first steps toward a proper wastewater treatment.
