Hanoi Sewage and Drainage Ltd. Company on July 9 discharged more than one million cubic metres of water from West Lake into To Lich River.
To Lich River
Phan Hoai Minh, deputy of the company, said that the move was intended to reduce the water level in the cityâ€™s lakes, ponds and rivers during the rainy season, including West Lake.
Minh added that at present the water level of the West Lake was around 25 centimetres higher than regulated. Pumping is expected to last two days.
The water would also help ease the pollution of To Lich River, Minh noted.
Hanoi is now using several methods to revive To Lich River, including Japanese and German technologies. Initially, this brought quite positive results as the river waterâ€™s oxygen content has increased.
Meanwhile, the company has also proposed the city to pump the Red Riverâ€™s water into West Lake and then discharge the lake into To Lich River.
