Rural small sponge projects, plastic rainwater pipes to improve the construction of village water treatment

In the process of promoting the construction of beautiful villages, small sponge projects are becoming a key measure to solve the stubborn problem of water accumulation in villages. In the past, many villages had the embarrassing situation of "watching the sea on the road and raising fish in the yard" every rainy season due to high road hardening rate and old drainage facilities. Now, relying on scientific planning, a decentralized rainwater management system with plastic rainwater pipes as the core is quietly changing this status quo.

Due to its smooth inner wall, small water flow resistance, moderate corrosion resistance and compressive strength, plastic rainwater pipes have become an ideal material for building village-level sponge bodies. In specific construction, a combination of "infiltration, stagnation, storage, purification, use and drainage" is usually used. The eaves rainwater riser is connected to the shallow seepage ditch, and the clean roof rainwater is preferentially introduced into the underground water storage module or ecological depression; the road surface runoff is collected through the linear drainage ditch, and after preliminary purification by the sand sedimentation well, it is transported by the large-diameter plastic rainwater pipe to the village rain garden or storage pond.

The beauty of this approach is that it does not simply drain the water, but realizes the local consumption and resource utilization of rainwater. The plastic piping system can flexibly adapt to the narrow roadways and complex terrain in the countryside, and through the combination of pipes and fittings, the rain and sewage can be easily diverted. The buried water storage module cooperates with the pipeline network to cut the peak and store during heavy rain to avoid overflow of water. After sunny days, the stored rainwater can be used for garden watering or public toilet flushing.

Compared with traditional cement pipes or brick trenches, the construction of plastic rainwater pipes is light and fast, has little impact on the daily lives of villagers, and has good sealing performance, which can effectively prevent groundwater pollution. Through this low-impact development model, the village not only gets rid of the trap of stagnant water, but also reshapes the ecological texture of "wet shoes on rainy days, rainwater has a place to go", so that the village can have a breathing drainage system while retaining homesickness.
