According to the agreement, the three parties will establish a comprehensive strategic partnership based on the principles of long-term vision, mutual advantage, market orientation, and win-win cooperation. They will jointly develop pipeline non-digging repair technology systems to promote the full-scale implementation and application of this innovative technology in urban water supply pipelines. This will significantly reduce traffic congestion caused by pipeline repair and renovation, thereby enhancing urban water supply safety and saving urban space while beautifying the city.
Urban Water Supply Pipeline Repair Needs
According to data from the Ministry of Housing and Urban-Rural Development, China's urban water supply pipeline length reached 920,082 kilometers in 2019, while the drainage pipeline length was 743,982 kilometers. Behind the continuous improvement of China's water supply network system and the rapid growth in the length of urban water supply pipelines, a significant issue that cannot be ignored is the increasing severity of pipeline aging, corrosion, and burst leakage.
Safe water supply benefits both the country and its people. Ensuring water safety is crucial for public health and social stability. The safety of urban water supply pipelines has become a common challenge worldwide, especially in the renovation and repair of these pipelines. Underground water supply pipelines have been in use for several decades, and their aging, corrosion, and leakage can affect water safety. Replacing or repairing urban underground water supply pipelines requires substantial financial investment and engineering work, which can cause environmental damage and severe traffic congestion.
Due to the limitations of conventional technical methods and the practical challenges in cost and technology faced by foreign companies in innovation applications, these issues have remained unresolved for a long time. Therefore, revolutionary innovative technological solutions are urgently needed to address problems such as aging and damage to water supply pipelines, corrosion, and pollution.
In urban water supply pipeline repair projects, the persistent issues of prolonged traffic congestion on roads and disruptions in residents' lives due to water shutdowns are common. How can these two major objective problems be resolved while also achieving comprehensive restoration of old water supply pipelines? Tunnel Investment and Shanghai DBC Group have been collaborating for a long time to research and experiment with solutions to this challenge, ultimately proposing the most efficient and safe technological innovation solution. Recently, both parties jointly developed and implemented a systematic solution for water supply pipeline repair technology with BASF, the world's largest chemical company.

On May 24, during a multi-party high-level strategic dialogue organized by DBC, representatives from Shanghai Urban Construction (Group) Co., Ltd., Tunnel Investment, Shanghai Water Conservancy Construction, DBC Group, and BASF engaged in comprehensive technical discussions on innovative organic urban renewal. They also conducted in-depth exchanges on the innovative research results of pipeline repair technology and reached a deep cooperation intention.
