ADB opens a new wastewater treatment plant in Arvaikheer, Mongolia

The Asian Development Bank (ADB) and the Uvurkhangai Provincial Government of Mongolia today inaugurated a new wastewater treatment plant in the provincial capital Arvaikheer. The state-of-the-art plant was built under additional financing for the ADB-funded Southeast Gobi Urban and Border Town Development Project, and will ensure safe, reliable, and environmentally friendly wastewater treatment for over 28,000 residents.

“The new plant replaces an inefficient treatment system that was built more than 30 years ago,” said Uvurkhangai Provincial Governor Mr Ganbold Gonchoo. “It is designed to meet current and future demand for the next 25 years and will play a significant role in the economic development and improved livability of Arvaikheer city. It is also an important milestone in the strategic partnership on urban development between ADB and the province.”

“The new plant is the first of ten similar facilities to be built in Mongolia with ADB support,” said ADB Country Director for Mongolia Mrs Yolanda Fernandez Lommen. “It will facilitate the town’s ongoing growth and development and will ensure that domestic and commercial wastewater will no longer be discharged into the local river basin.”

The plant was opened ten months ahead of plan and has an operating capacity of 3,000 cubic meters per day. It features integrated fixed-film activated sludge technology designed by Mongolian engineers and produces high quality effluent through effective and energy-efficient treatment processes. The plant will reduce odor and adhere to strict environmental conditions and national effluent standards.

Established in 1966, it is owned by 67 members—48 from the region. In 2017, ADB operations totaled US$32.2 billion, including US$11.9 billion in cofinancing.
