China will invest approximately 90 billion yuan to fight water pollution in the next two or three years, said Wu Xiaoqing, vice minister of environmental protection.

The money will be spent in building wastewater treatment plants, water distribution systems and facilities to collect and recycle rain water in a bid to expand the nation's sewage treatment capability, he said in Beijing on Monday.

Despite a large amount of money already funneled into the treatment of polluted major rivers and lakes, not much headway has been achieved, he added.
