War on water hyacinth begins

CITY public sanitation authorities have started fighting against the annual invasion of water hyacinth in the Huangpu River and Suzhou Creek, officials said yesterday.

More than 28,000 tons of water hyacinth has so far been taken out of the water, according to the water management department of the Shanghai Greenery and Public Sanitation Administrative Bureau.

Coming from the upper reaches of the Huangpu River, the water hyacinth covered more than 100,000 square meters from Zhagang to Mishidu areas, a distance of about 20 kilometers, the bureau said.

District officials have started blocking the flow of the plant at mouths and tributaries.

Officials said although the plant had not yet hit scenic areas of the river, consequences would be serious without immediate action.

Jinshan and Qingpu districts have the most serious invasion of water hyacinth. During the past month, the two districts yielded a total of 41,000 tons, officials said.

"This year the water hyacinth problem may be as serious as last year," said Yu Hai, an official with the department.

"The cleaning up is expected to last to January."

Last year the city cleaned out 166,600 tons of water hyacinth.
