Hanoi has installed 10,000 water treatment units and will incorporate 5,000 more at the end of this year in the city’s four suburban districts of Ung Hoa, Phu Xuyen, Thuong Tin and Thanh Oai.

According to the city’s Centre for Clean Water and Rural Sanitation, the work is part of a four-year plan to install 40,000 units of water treatment equipment for poor households in the districts, especially in areas polluted by groundwater.

So far, the centre is examining the arsenic level in water sources across Hanoi, with the results to be announced at the end of the year.-VNA
