Overview
Guangxi wastewater treatment plant serves Beihai, Guangxi, China, with a designed capacity of 1.00 and a population served of 400,000. It is located within 50 km of the coast, discharging into local waterways.
The Guangxi wastewater treatment plant is located in Beihai, a coastal city in the Guangxi Zhuang Autonomous Region of southern China. The facility serves a population of approximately 400,000, placing it in the large agglomeration category under Chinese wastewater regulations. The plant's designed capacity is 1. China's wastewater treatment standards are governed by the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants serving populations over 100,000. Plants of this scale are typically required to achieve Class 1A or 1B effluent standards, especially when discharging into sensitive water bodies or coastal areas. The plant is situated within 50 km of the coast, indicating its discharge likely reaches the Gulf of Tonkin via local rivers or drainage channels. The proximity to the coast suggests potential impacts on marine ecosystems. The plant plays a key role in protecting the coastal waters of the South China Sea from untreated wastewater, supporting local fisheries and tourism.
Environmental context
The plant's discharge ultimately flows into the Gulf of Tonkin, a semi-enclosed basin of the South China Sea that supports diverse marine life, including coral reefs and mangrove forests. The coastal waters near Beihai are ecologically sensitive, hosting important nursery grounds for fish and shellfish. Effective wastewater treatment is critical to prevent eutrophication and protect the region's marine biodiversity.
