Overview
Sichuan wastewater treatment plant serves Pengzhou, a suburb of Chengdu in Sichuan Province, China. It treats wastewater from approximately 173,500 people, supporting the region's water quality management.
The Sichuan wastewater treatment plant is located in Pengzhou, a city under the administration of Chengdu, the capital of Sichuan Province in southwestern China. The facility serves a population of about 173,500, placing it in the medium-to-large agglomeration category for Chinese wastewater infrastructure. Its location in the densely populated Chengdu Plain underscores its role in managing urban wastewater from a rapidly developing area. The plant operates under China's national wastewater discharge standards, which are enforced by the Ministry of Ecology and Environment. For a facility of this scale, secondary treatment with nutrient removal is typically required to meet the Grade 1A or 1B standards under the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The plant's capacity and performance are subject to regular monitoring by local environmental authorities. The treated effluent likely discharges into a tributary of the Min River, which flows through the Chengdu Plain and eventually joins the Yangtze River. The Min River is a critical water source for the region, supporting agriculture, industry, and domestic use. Proper treatment at this plant helps protect downstream ecosystems and water quality in the Yangtze River basin, one of China's most important watersheds.
Environmental context
The plant is situated in the Chengdu Plain, part of the upper Yangtze River basin. Treated wastewater likely enters a local tributary of the Min River, which flows southward through Sichuan and into the Yangtze at Yibin. The Min River supports diverse aquatic life and is a key water source for irrigation and urban supply. Downstream, the Yangtze River estuary and East China Sea receive the cumulative discharge, making nutrient and pollutant control essential for coastal water quality.
