Nei Mongol Wastewater Treatment Plant, Keshiketeng Banner, Inner Mongolia

The Nei Mongol wastewater treatment plant is located in Keshiketeng Banner (Hexigten Banner), within Chifeng City, Inner Mongolia Autonomous Region, China. It serves a population of approximately 42,000 residents in the area. The plant is situated in a region characterized by a continental climate and steppe landscapes. As a municipal facility, the plant is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For agglomerations of this size, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The treated effluent likely discharges into a local river or stream within the Xiliao River basin, which ultimately flows into the Bohai Sea. The plant plays a key role in protecting local water resources and downstream aquatic ecosystems from untreated wastewater pollution.

The plant is located in the Xiliao River basin, which drains into the Bohai Sea via the Liao River system. The region supports diverse aquatic life and is important for migratory birds. The plant's discharge helps maintain water quality in local rivers that are used for irrigation and ecological balance.
