On November 14, 2024, the 26th China International High-Tech Fair and the Guangdong-Hong Kong-Macao Greater Bay Area Environmental Water Expo officially commenced at the Shenzhen International Convention and Exhibition Center.

Leaders from the Shenzhen Water Authority, Shenzhen Water Group, Zhuzhou Water Group, and the China Association for Science and Technology, along with media representatives, visited and interviewed at the HydroVita booth. Through the introduction by the staff, they highly commended the fourth-generation drainage system—the Intelligent Sewage Diversion System. They recognized its integrated tripartite solution and the online command and offline regulation mechanism as truly capable of resolving the water environment issues in Chinese cities.

At this exhibition, HydroVita showcased the "Fourth-Generation Drainage System—Intelligent Sewage Diversion," an upgraded version of the traditional rainwater and sewage separation system. It addresses the issue of sewage entering rainwater pipelines post-separation, the problem of non-compliant river and lake water quality due to initial rainwater surface pollution, and the challenges of low influent concentration at wastewater treatment plants and overflow in sewage pipelines caused by external water ingress. Compared to traditional renovation methods, it can save on engineering costs, wastewater treatment expenses, and later operation and maintenance fees, making it the optimal choice for cost-effectively solving urban water environment issues.

This technology has received high recognition from the Ministry of Ecology and Environment, the Ministry of Housing and Urban-Rural Development, the Ministry of Science and Technology, and the Ministry of Water Resources, and has been promoted nationwide. To date, it has been successfully applied in over 1,000 projects across more than 70 cities in China, providing a robust precondition for 1.4 billion Chinese people to access healthy water resources.
