Hanoi authorities and Japanese consultants are working on a project to construct two plants to treat waste water in a bid to further improve the environment in the capital city in the 2010-2020 period.
They met in Hanoi on Dec. 25, 2008 to discuss a wide range of aspects around the project, including the plants’ designs, financial estimations, construction timetable, and related institutional and socio-environmental issues.
According to the joint consultant teams comprising experts from Nippon Koei of Japan and the Vietnam Water and Environment Joint Stock Company (VIWASE), the Yen Xa plant will be built on 13 ha in Yen Xa village, Hanoi’s outlying Thanh Tri district, capable of treating around 270,000 m3 a day.
Meanwhile, the Phu Do plant will be built on about 6 hectares in Phu Do village in the outlying district of Tu Liem and it will be able to process 84,000 m3 of waste water a day.
According to the consultants, only 24 households in Thanh Tri and Tu Liem districts will have relocate for the construction of the two plants.
They proposed the construction, which is estimated to cost VND 10 trillion in total, should be carried out in two phases with the first phase scheduled to be completed in 2015 before operating in full in 2020.
Once completed, those plants are expected to improve water quality in Hanoi’s rivers, particularly the To Lich.
The To Lich river, which has linked to Hanoi’s development for 1,500 years as a source of irrigation water supply to suburban agricultural land and fish farms, has been chronically polluted by untreated or badly treated waste water and solid waste from many nearly production establishments and households.
