Work started on the project in June 2016, aiming to manage high tide flooding and respond to climate change effects over an area by the Saigon River spanning 570 square kilometers and home to 6.5 million people.
Invested under the build-transfer model, the VND10 trillion ($426 million) project runs through districts 1, 4, 7, 8, Nha Be and Binh Chanh with six tidal sluice gates. It also has several dykes spanning 7.8km along the river.
Originally set for completion within three years, the project was briefly stopped in April 2018 due to a lack of capital and then delayed again starting November 2020 because the city administration had not signed a contract extension.
The contract signed with the project's builder, city-based Trung Nam BT 1547 Co. Ltd, expired in June 2020.
Since the contract was not extended, the bank refused to disburse the remaining sum of VND1.8 trillion ($77.6 million) for Trung Nam to continue the project.
