water pollution is a serious issue in vietnam as a result of rapid industrialization and urbanization without adequate environmental management. as of 2008 only 10 percent of municipal wastewater was treated, and only 45% of industrial zones were expected to have wastewater treatment of some kind in 2010. the pollution of rivers and lakes in hanoi is "alarming" according to municipal authorities, as up to 98 per cent of 200 rivers and lakes fail to meet the required water quality. sewer systems consist of combined sewers, channeling both rainwater and municipal sewage. small enterprises engaged in food processing and textile dyeing in so-called "craft villages", of which there are 700 in the red river delta alone, discharge untreated wastewater. an analysis by the university of technologies and the ministry of science and technology showed that 100% of wastewater samples taken from craft villages exceed allowed levels of pollution. vietnam also has more than 200 registered industrial zones without sustainable wastewater treatment. industrial zones discharge 1 million cubic meters of untreated sewage per day, about 70 percent of all industrial wastewater. 8 industrial zones will be equipped with wastewater treatment plants with the help of a us$50 million loan from the world bank approved in 2012. it is also planned to construct 30 wastewater treatment plants in the mekong delta until 2020, including 13 plants for domestic wastewater treatment and 17 for industrial wastewater treatment in can tho, a giang, kien giang and ca mau provinces. in 2012 hanoi expected to start the operation of the upgraded yen so waste water treatment plant with a design capacity of 200,000 cubic meters per day; eight more wastewater treatment plants are planned in hanoi alone.
