Protecting Biodiversity, International Water Association Water Biosafety China Committee Praises Dali Sinking Regenerated Water Plant

On May 22nd, on International Biodiversity Day, the first research activity of the International Water Association's China Committee on Water Biosafety (hereinafter referred to as M.S. Water) was held at the Dali Submerged Reclaimed Water Plant of China Water Environment Group.

Joan Rose, honorary chairman of M.S. Water, winner of the Stockholm Water Prize, academician of the National Academy of Engineering, Gertjan Medema, winner of the Lee Kuan Yew Water Prize, chief scientist of KWR Water Research Institute in the Netherlands, Blanca Elena Jim é nez Cisneros, winner of the Nobel Peace Prize, Mexican ambassador to France, Zhang Lujing, vice president of China Water Environment Group, and others went to Dali Old City for research, sharing and discussing the important role of renewable water technology in water resources protection, biodiversity improvement, and urban sustainable development.

M. S. Water experts visited the inlet and pre-treatment area of the recycled water plant, gained a detailed understanding of the sewage treatment process and effluent standards, and highly praised the efficient operation and excellent performance of the ancient city's recycled water plant.

In 2022, the International Water Association (IWA) awarded the Project Innovation Award to the Dali Project of China Water Environment Group. The project involves the construction of six sunken recycled water plants around Erhai Lake, forming a major artery that cuts off and reuses the domestic sewage around Erhai Lake like a pearl necklace. One of them is the ancient city sinking type recycled water plant. By sinking the water plant, the problem of neighboring avoidance is completely solved, and water and land resources are fully utilized, playing an important role in the sustained improvement of water quality and fundamental changes in the ecological environment of Erhai Lake.

The sunken recycled water plant and seaweed are important indicators for measuring the water ecosystem in Dali. By examining these facilities and aquatic plants, M.S. Water experts have gained an understanding of the safety status of aquatic organisms, biodiversity, and ecological balance in aquatic ecosystems.

Aquatic biosecurity is a global issue that requires joint efforts from all countries to address. Through this inspection and exchange, international cooperation and exchange have been promoted, and China's experience and technology in water ecological protection and restoration have been shared, promoting the healthy and sustainable development of global water ecosystems.
