Overview
Sichuan wastewater treatment plant serves Qionglai City in Sichuan Province, China, with a population of 111,800. It operates under China's national wastewater regulations.
The Sichuan wastewater treatment plant is located in Qionglai City, part of Chengdu prefecture in Sichuan Province, China. It serves a population of approximately 111,800, placing it in the medium-to-large agglomeration category for Chinese municipal wastewater infrastructure. As a plant serving over 100,000 people, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment as a minimum and often requires advanced treatment for sensitive receiving waters. The plant's discharge likely flows into local rivers within the Yangtze River basin, which is the largest river system in China and a critical water resource for the region. The plant's treated effluent ultimately drains into the Yangtze River via its tributaries, supporting downstream ecosystems and water supply. The Yangtze basin is home to diverse aquatic life, including endangered species such as the Yangtze finless porpoise, and is subject to stringent pollution control measures under China's Water Pollution Prevention and Control Law.
Environmental context
The plant discharges into local waterways that are part of the Yangtze River basin, China's largest and most ecologically significant river system. The Yangtze supports a wide range of aquatic biodiversity, including migratory fish species, and provides water for agriculture, industry, and drinking water for millions of people downstream. Effective wastewater treatment is crucial to prevent eutrophication and protect the river's ecological health.
