The city of Xiangyang (1.2 million inhabitants), which is crossed by the Han River, is expecting strong urban development. It will mainly occur in the new Dongjin district, which is currently being built. The existing sanitation system is operating at its full capacity. Consequently, it appeared essential to build a new wastewater treatment plant.
The project aims to provide the new Dongjin district with a wastewater collection and treatment system equipped with the best technologies. There are two objectives: Exemplary urban development in terms of the environment; Increased water resources protection.
The future plant has a capacity of 100,000 m3 a day. It has been scaled to satisfy needs in the area for 2020 and designed to meet the highest treated water quality requirements. The treated water will be discharged downstream from the city into the Han River, which is an essential resource for the water supply of riparian populations.
By 2060, the wastewater treatment plant should have a capacity of 660,000 m3 a day and treat the wastewater of some two million inhabitants. The new wastewater treatment plant treats all the wastewater (mainly domestic) from the new Dongjin district, as well as the effluents from the Shenzhen industrial park in the north of the city. The treated effluents are discharged into the Han River downstream from the city and Cuijiajing dam, which preserves the quality of the upstream reach.
- Development of the sanitation system (collection network, wastewater pumping and treatment); The processes implemented provide advanced effluent treatment, which ensures the project has a minimum impact on the receiving environment. The sludge produced will be recovered via additional treatment (digestion and composting) at a plant recently commissioned for this purpose;
- The new Dongjin urban district and its 230,000 residents benefit from high-quality collective sanitation by 2020.
