MANILA, PHILIPPINES – Huangshi, a secondary city in southeastern People’s Republic of China (PRC), Hubei Province, is testing an integrated approach to urban pollution control that combines reducing upstream pollution with improving downstream water quality, using a $100 million loan from the Asian Development Bank (ADB).
“The project has a great potential to become a model for integrated pollution control, and ecological rehabilitation efforts to clean up polluted and blocked urban lakes in small and medium-sized cities in the PRC,” said Diwesh Sharan, Director of Urban and Social Division at the East Asia Department.
The city is part of a megacity cluster around Wuhan that the central government is promoting as a pilot administrative zone for balanced, environment-friendly economic development.
Situated on the southern floodplain of the Yangtze River, Huangshi’s historical reliance on heavy industry and inadequate investment in urban infrastructure has left a legacy of environmental and urban development challenges.
Untreated industrial and domestic wastewater has flowed into the three lakes within Huangshi city; at the same time, urban channels and lakes are blocked by sediments and accumulated solid waste, endangering the health of many poor people who live near the waterways.
The project will build and rehabilitate 60-kilometer sewer networks in urban areas, and a wastewater treatment plant with a capacity of 30,000 cubic meter per day. It will remove 1.55 million cubic meter of contaminated sediments from Cihu, Qingshan, and Qinggang lakes. It will also build engineered wetlands, ecological embankments, and sludge treatment facilities, and build and upgrade solid waste collection and transfer stations.
The project will benefit around 765,000 of Huangshi’s urban residents.
