Hefei will spend another 50 billion yuan ($8.2 billion) controlling pollution and improving the environment of Chaohu Lake this year, Xin'an Evening News reported on Wednesday.
The move comes after the first phase of a project for comprehensive treatment of the lake, worth more than 50 billion yuan, kicked off last November.
Estimated at a cost of 53.4 billion yuan, the second phase includes pollution control, road construction and renovation, afforestation and structural adjustment of agriculture. It is slated to be launched in August, local authorities said.
Further, the third phase of the project is expected to be started in late 2013, largely to divert water from the Yangtze River, the third longest waterway in the world, to the lake.
