In 2000, the canal that flows two kilometers through Districts 5 and 6 was filled up following heavy pollution and serious encroachment. By then, the canal spread only two kilometers wide with blackish and stinky water.
To continue its drainage function, a concrete box culvert was installed.
Fifteen years later, the city decided to recover the canal with a three-phase project that cost VND2 trillion ($86.2 million) to build a drainage system and relocate affected households.
The project was to complete in 2020 but got delayed.
In 2020, a section 200 meters long and 14-16 meters wide in District 6 was revived, with the two banks turned into a park.
