Hebei Wastewater Treatment Plant, Longyao County, Hebei Province

The Hebei wastewater treatment plant is located in Longyao County, Hebei Province, China, serving a population of approximately 63,000. As a municipal facility, it plays a key role in managing wastewater from the county's urban and peri-urban areas. Under China's national wastewater discharge standards (GB 18918-2002), plants serving agglomerations of this scale are typically required to achieve at least secondary treatment, with nutrient removal in sensitive watersheds. Regulatory compliance is expected. The treated effluent likely discharges into a local watercourse that flows through the Hai River basin, ultimately reaching the Bohai Sea. The plant's operation helps protect downstream water quality and supports the ecological health of the region's rivers and coastal waters.

The plant is situated in the Hai River basin, which drains into the Bohai Sea. The receiving water body is likely a tributary of the Hai River system, which supports diverse aquatic life and is important for regional agriculture and fisheries. Downstream, the Bohai Sea is a semi-enclosed sea with significant ecological and economic importance, requiring careful management of nutrient and pollutant loads.
