HANGZHOU government will remove 88 sandstone wharves next year to protect water resources at Qiantang River and guarantee safe drinking for the city's 7 million residents.
Currently, Qiantang River provides more than 80 percent of drinking water for residents with the rest coming from eastern Tiaoxi River.
However, sandstone wharves, sand excavation sites, shipyards and water gas stations along both sides of Qiantang River have compromised the purity of drinking water.
The river's water quality has been frequently drawn to the attention of authorities.
Therefore, Hangzhou government has ordered a stop to sand mining and removal of all sandstone wharves within first-level water resource protection areas by the end of next year.
Intakes at Jiuxi Waterworks have been affected by oil pollution several times, most recently on December 1.
This part of the river is within Qiantang River's first-level water resource protection area.
With a total length of 41.2 kilometers, the section starts from the junction of Qiantang River's Dayuan Creek and Fuchun River, and ends at Sanbao Ship Lock.
It contributes a daily water intake of 2.67 million cubic meters, accounting for 80 percent of Hangzhou's total supply.
The pollution resulted from wharves loading and unloading sandstone and waste from shipyards.
In addition to oil pollution, elements such as iron, manganese, dissolved oxygen and nitrites are threatening water quality at different waterworks in Hangzhou.
According to the local government's survey, there are a total of 88 sandstone wharves between the junction of Qiantang River's Dayuan Creek and Fuchun River and Jiuxi Waterworks.
Also, more than 1,000 cargo ships are adding to the pollution dumping waste oil and sewage.
Water gas stations at Xinsha Village of Shuangpu Town and those at Yushan Town are also threatening water safety.
"It's a great workload to protect the river," says Hangzhou Mayor Cai Qi. "But we have to take action."
According to the government plan, a scheme will be worked out by the end of this month to remove and eliminate the sandstone wharves.
By the end of next March, a third of the project should be completed and the rest done by the end of next June.
Four enterprises, including Zhejiang Haizhou Shipbuilding Co Ltd, Hangzhou Yuanpu Shipyard Co Ltd, Hangzhou Dongfang Shipyard Co Ltd and Xiaoshan Fuchun Shipyard will finish relocation at the latest by the first half of 2011.
