Asia's largest underground water recycling plant to start operation before year’s end

Located under Beijing’s South Fourth Ring Road, construction on the city’s first fully enclosed underground water recycling plant will finish in June of this year, and the plant will be put into use before the end of 2016. 

With a total area of 450,000 square meters, the Huaifang Water Reclamation Plant is also Asia's largest fully enclosed underground recycling plant. It has a planned watershed area of 137 square kilometers, and its daily sewage treatment capacity will be 600,000 cubic meters. Most of the sewage from the western part of Beijing proper can be collected and processed here.

Operating at full steam, the plant is able to process up to 200 million cubic meters of wastewater every year, the equivalent of Kunming Lake 100 times over. Treated water will mainly be used in industrial and commercial settings, along with a wetland park. The rest will be returned to Xiaolong River.
