Hungary-financed wastewater treatment plant opens in Laos’ capital – photos

A new wastewater treatment plant financed through a Hungarian tied aid credit facility has been officially inaugurated in Vientiane, marking a major upgrade to the Lao capital’s urban infrastructure.

The project, with a total value of approximately USD 90 million, is the largest Hungarian-supported development implemented in Laos to date. Together with its associated sewer network, the facility has a daily treatment capacity of 52,000 cubic metres and will serve around 160,000 residents, covering four of the capital’s nine districts.

The new plant is expected to significantly improve local sanitation, public health, and environmental protection, reducing pollution in rivers and surface waters while supporting the sustainable growth of the rapidly expanding city.
The investment is part of a broader framework of Hungarian–Lao tied aid credit agreements, under which projects worth a combined USD 213 million have been launched over the past 17 years. These programmes have focused on key sectors including water management, agriculture, food safety, fisheries, and digital public administration.
