The Asian Development Bank will give China a loan of US$100 million to help clean up waterways in Wuhan. The Philippines-based lender said Tuesday the money would be used to build or upgrade wastewater treatment facilities, repair and extend collection networks and add stormwater-pumping capacity. Despite plenty of water resources Wuhan's eight million people face a serious pollution problem. Some 56% of its rivers and 89% of its lakes are polluted due to wastewater discharges that sometimes go untreated, AFP reported. During the wet season, sewers are prone to overflow. The proposed project would add 10% capacity to the city's ability to treat wastewater.
