Hebei Wastewater Treatment Plant, Rongcheng County, Xiong'an New Area

The Hebei wastewater treatment plant is situated in Rongcheng County, part of the Xiong'an New Area in Hebei Province, China. It serves an estimated population of 70,000 people, placing it in the medium agglomeration scale for Chinese municipal wastewater infrastructure. As a facility in China, the plant operates under national wastewater discharge standards, which typically require secondary treatment for urban wastewater. For agglomerations of this size, Chinese regulations mandate compliance with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits on key pollutants to protect receiving water bodies. The plant discharges into local waterways that ultimately drain into the Hai River basin, a major system flowing into the Bohai Sea. The downstream environment supports diverse aquatic life and is important for regional water resource management, especially given the water-scarce conditions in northern China.

The plant's treated effluent enters the local river network within the Hai River basin, which flows eastward into the Bohai Sea. This watershed is ecologically significant as it supports freshwater habitats and agricultural irrigation in a region facing water scarcity. The Bohai Sea is a semi-enclosed marginal sea with sensitive marine ecosystems, making pollution control critical for maintaining water quality and biodiversity.
