SUEZ NWS Wins Industrial Wastewater Treatment Project in Dongying to Optimize Water Resources

Following a project win to treat drinking water in Qingdao, Shandong, SUEZ NWS has recently won a contract with total investment of RMB 300 million for centralized wastewater treatment in the Dongying Chemical Industry Park located in Dongying, Shandong. The project will boost local efforts to better manage water resources and further improve the environment.

The envisaged wastewater treatment plant (WWTP) in the Dongying Chemical Industry Park will have a treatment capacity of 26,000 m3 per day. A joint venture[1] formed between SUEZ NWS and its local partner will be responsible for the investment, construction and operation of the plant. The plant will provide industrial wastewater treatment services exclusively for enterprises in the park for the next 50 years. Construction work will begin in late 2019 and be completed by late 2020. Upon its completion, the plant will provide centralized treatment of existing industrial wastewater streams in the park. It will also have capacity to meet the growing treatment demand from future park projects. The WWTP will ensure the production of high-quality treated wastewater in compliance with standards, and the reuse of 40% of this water to supply the industries of the Park. This will greatly improve the water environment and drive the local circular economy.


Wang Feng, Deputy Secretary of the Dongying District Party Committee and District Head, said: "We hope that SUEZ NWS will exert its rich experience in the construction, operation and management of wastewater treatment plants in this project to promote the centralized treatment of wastewater in the park and concentrate on emission to effectively improve the district’s environment. We also hope that it can improve the efficiency of water use, solve the predicament between industrial water supply and demand, and comprehensively accelerate the park’s upgrade."


Dongying City is an important oil base in China and the Dongying Chemical Industry Park hosts key players[2] in the petrochemical industry. In recent years, the Park has striven to become a safe, high-end park in pursuit of green growth. The total industrial output value of the Park exceeded RMB 100 billion in 2018.


SUEZ NWS first entered Shandong in 2002, taking over 90% of the drinking water production in Qingdao City through its local JV. Its daily supply capacity is 726,000 m3 and the population served reached 2.5 million. Water from this plant meets EU drinking water standards. In 2013, again through another new JV, SUEZ NWS took over responsibility for investing, building and operating a WWTP in the Dongjiakou Economic Development Zone in Qingdao. It expanded its commitment to include exclusive provision of domestic and industrial wastewater treatment services for enterprises in the zone for 30 years. The WWTP currently treats 20,000 m3 of industrial wastewater daily.
