Chongqing Tangjiatuo WWTP protects water resources of the upper-middle reaches of Yangtze River
Chongqing, located in the area of the Three Gorges Reservoir, at the intersection of multiple water bodies, has a large population. It boasts prosperous economy, while at the same time, shoulders an arduous responsibility for environmental protection. In 2007, SUEZ took over the management of Chongqing Tangjiatuo Wastewater Treatment Plant by the TOT model, starting to provide wastewater treatment services for over one million citizens in Jiangbei District, Yubei District and Liangjiang New Area.
Protecting water resources of the upper-middle reaches of Yangtze River
WWTP with the most complete processes and advanced technologies
Harmless treatment and resource recycling of sludge
Exploit resources from wastewater
The plant has built a treated wastewater power plant with an installed capacity of 800Kw, which can directly substitute 10% of the plant's electricity usage for production. In addition, the plant is equipped with a water reuse system, which is applied to greening, road cleaning, equipment cooling and other applications in the plant, saving about 94% of the water use across the whole plant.
- Tangjiatuo WWTP provides daily municipal wastewater treatment services for 1 million citizens, covering an area of 100 km2 in Jiangbei District, Yubei District, and Liangjiang New Area, Chongqing, with a daily wastewater treatment capacity of 400,000 tons, and daily sludge drying capacity of 240 tons. It effectively protects the water resources of the upper-middle reaches of Yangtze River and guards the quality of living in Chongqing.
- The plant has creatively adopted resource recycling solutions, such as biogas production from anaerobic digestion of wastewater sludge, treated wastewater power generation, and water reuse facilities, to greatly reduce the consumption of natural gas, electricity and water resources.
- In the first selection of the benchmark wastewater treatment plant in celebration of the 100th anniversary of the founding of the People’s Republic of China and the CPC, Tangjiatuo WWTP won two benchmarks for its operation management and precise control in critical processing.
