The city's drainage system often tests our patience and courage inadvertently, especially in heavy rain, we step through puddles and anxiously wait for the water to gradually recede. But now, imagine if the city has a smarter and more efficient drainage solution, then those days of being besieged by rainwater may become a thing of the past. This is no longer an unattainable dream. The advent of plastic infiltration wells and overflow wells provides an innovative and efficient solution to the city's drainage problems, making the city's drainage system more scientific and management more intelligent. These facilities can not only effectively control and manage the flow of rainwater, but also prevent the occurrence of waterlogging in extreme weather conditions. Plastic infiltration wells, using advanced engineering technology, can effectively divert the accumulated water on the road into the ground, lower the ground water level, and thus reduce the impact of accumulated water on urban traffic and daily life. Through the design of vertical holes, the amount of water seepage doubles with the increase of depth. This design not only saves ground space, but also greatly improves drainage efficiency.
