Overview
Sichuan wastewater treatment plant serves Kangding (Dardo) in Sichuan, China, with a population of 33,700. The plant operates under China's national wastewater standards.
The Sichuan wastewater treatment plant is located in Daping Village, Kangding (Dardo), within the Garzê Tibetan Autonomous Prefecture of Sichuan Province, China. It serves a population of approximately 33,700, placing it in the medium agglomeration category for Chinese municipal wastewater infrastructure. Under China's national wastewater discharge standards (GB 18918-2002), plants of this scale are typically required to achieve at least secondary treatment to protect receiving water bodies. The regulatory framework mandates compliance with effluent limits for pollutants such as COD, BOD, and ammonia nitrogen. The plant discharges into the local watershed, which ultimately drains into the Yangtze River basin via the Yalong River or Dadu River tributaries. This region is ecologically sensitive due to its location on the eastern edge of the Tibetan Plateau, supporting diverse aquatic life and serving as a water source for downstream communities.
Environmental context
The plant's receiving waters flow into the Yangtze River basin, one of China's most important ecological and economic waterways. The region's high-altitude environment supports unique aquatic biodiversity, including endemic fish species. Downstream, the river system provides water for agriculture, industry, and drinking water for millions. Protecting water quality in this headwater region is critical for maintaining ecosystem health and meeting national water quality standards.
