Hanoi authorities are planning to clean several polluted rivers and improve their surroundings.
The 14-km To Lich River, which runs through Ba Dinh, Cau Giay, Dong Da, Thanh Xuan, Hoang Mai and Thanh Tri districts is notorious for its pollution.
The water in Ta Thanh Oai Commune, Thanh Tri District, has a black colour and foul smell after being polluted with all kinds of wastewater.
Nhue River, another polluted river runs through Ta Thanh Oai, also has black water. The high population density along Nhue River means a huge amount of domestic wastewater is discharged daily.
In Ha Dong District, Day River has also been polluted for years. Littering from the residents and the waste from the local plastic recycling facility are accused of destroying the river. The river also looks smaller than its actual size because of the huge amount of duckweed.
The To Lich, Set and Lu rivers are part of the city's drainage system. Yet both To Lich and Lu rivers are severely polluted. Rubbish can be seen floating on the surface of Lu River and the water is almost black.
Sewerage and Drainage Company 4 had asked the residents to stop throwing rubbish into the river to no avail.
