Hanoi to Use 24 Hectares of Land for Cau Bay River Pollution Treatment Project

Hanoi is preparing to dedicate at least 24 hectares of land for a critical project aimed at treating pollution in the Cau Bay River. The city's People's Committee has submitted a proposal to the City People's Council for consideration, outlining the ambitious plan. The overall project is estimated to cost over 11.6 trillion Vietnamese dong (approximately $450 million USD) and will span more than 327 hectares across seven communes and wards. It is slated for implementation between 2026 and 2028 under a build-transfer (BT) contract.

The initiative is divided into two main components. The first involves constructing wastewater collection systems and treatment plants, with an estimated cost of over 7.2 trillion dong. This includes building approximately 78 kilometers of sewage pipelines and five wastewater treatment plants, such as the Phuc Dong and An Lac facilities. Additionally, a 7-kilometer collection system will be added for the Ocean Park urban area and nearby residential zones. To finance this part, Hanoi proposes using six land plots totaling over 24 hectares in various districts.

The second component focuses on rehabilitating the Cau Bay River itself, with an estimated cost of over 4.4 trillion dong. This phase includes dredging and embankment work along about 6 kilometers of the river, constructing a 0.5-kilometer water supply pipeline, and building a pumping station with a capacity of 5 cubic meters per second. A 10-hectare sedimentation pond will also be created. Furthermore, a 14-kilometer riverside road, with two to four lanes, will be built, alongside the expansion of two existing bridges. The payment method for this component will be determined based on the value of the allocated land plots.
