Yichang sponge city construction, plastic drainage pipes help rainwater storage project

With the steady landing of Yichang sponge city construction, the rainwater storage project, as the core link, is ushering in a fine upgrade. In the whole chain of urban rainwater storage and discharge, plastic drainage pipes have become an important support for the advancement of the project by virtue of their many adaptability advantages.

Compared with traditional pipes, plastic drainage pipes have excellent corrosion resistance, can adapt to the complex underground soil environment and rainwater pH, and are not easy to be damaged and blocked after long-term use, ensuring the long-term smooth flow of rainwater storage channels. At the same time, its lightweight characteristics greatly reduce the difficulty of construction, facilitate transportation and underground laying, and adapt to the terrain characteristics of Yichang mountains and hills. While shortening the project cycle, it also reduces the impact on urban traffic and residents' lives.

In the rainwater storage system, plastic drainage pipes are closely connected to sponge facilities such as rain gardens and sunken green spaces to efficiently undertake surface runoff, divert rainwater to storage tanks or infiltration systems, and realize rainwater resource utilization and waterlogging prevention and control. This adaptability application not only fits the construction concept of sponge city "seepage, stagnation, storage, purification, use, and drainage", but also provides a solid drainage guarantee for Yichang to create an ecological and livable urban environment.

At present, a number of sponge city pilot areas in Yichang have completed the large-scale laying of plastic drainage pipes, which has significantly improved the efficiency of rainwater storage, effectively alleviating the problem of local waterlogging during the flood season, and accumulating replicable practical experience for the subsequent construction of global sponge cities.
