Nhieu Loc-Thi Nghe, widely considered the most polluted cannel in Ho Chi Minh City, has got a face lift, showing a huge difference.
The drainage system of the canal’s basin receives both household and rain water drainage, causing obviously dirty and smelly water.
Since 2003 the city has carried out a project on the canal’s basin area, focusing on the construction of a sewer system along the canal's shore to collect the discharge of wastewater and rain for pre-treatment before being discharged into the canal.
Also, the canal has been frequently dredged for several years. The technology used for the project is expected to bring Nhieu Loc-Thi Nghe canal to its original state. Its banks are also being beautified with trees and green spaces.
