Underground water treatment plant to make waste useful

The largest underground water recycling plant in Asia is expected to be completed in Beijing by the end of June, according to the Beijing Drainage Group, a large public-service enterprise in the capital and the operator of the plant.

The Huaifang Water Recycling Plant, which will be capable of recycling 200 million cubic meters of sewage a year and able to treat most wastewater from Beijing's western urban area, will contribute greatly to the city's environmental protection, according to the city's publicity department.

The facility, which is located in the capital's southwest, was built underground to save valuable land. It occupies an area of more than 16 hectares and is equipped with cutting-edge technology, the group said.
