The Phase IV project of the Jiangbian Sewage Treatment Plant in Changzhou City, Jiangsu Province passed the quality inspection and acceptance on October 28.

A key part of the national clean water initiative in the Taihu Lake basin during the 13th Five-Year Plan period (2016-2020), the project also plays a pivotal role in Changzhou’s conservation of the Yangtze River and fight against water pollution.

Changzhou has built and put into operation four plants, which are able to dispose over 96 percent of sewage generated. The city has made gradual progress in eliminating "black and odorous" water bodies in urban waterways and extending the sanitary sewer to collect and transport more wastewater for centralized treatment.

The Phase IV project was launched as a necessity in order to improve treatment capacity after the joining of wastewater network in areas including the High-speed Railway Town community, the Huanghe Road mechatronics industry belt and the biomedical park.

The project started in August 2018 and included the building of  facilities and a set of complex disposal system that involves different stages of processing. The treated wastewater can meet the surface water quality at Class IV, which is mainly good for industrial use and entertainment not directly touched by human bodies.

The completion of the project can increase the city's sewage treatment capacity by 200,000 tons per day. Treatment capacity in the city's downtown area will reach 750,000 tons per day and the reclaimed water will increase by 120,000 tons per day.
