Combined Application of Drainage Boards and Water Storage Modules in Sponge City Construction

In sponge cities, green roofs of garages, and rainwater recycling systems, the combination of drainage boards and water storage modules is a good solution. The drainage boards can quickly remove excess rainwater, preventing water accumulation, reducing flood risks, and protecting the roof and the root systems of plants. The water storage modules are responsible for collecting the clean rainwater that has been drained and storing it for use in irrigation, reuse, and slow infiltration. This combination can not only quickly drain floodwaters but also store water for reuse, without occupying ground space. It is one of the most commonly used forms of sponge systems in residential areas, parks, and garage roofs.

Advantages of the combination:

◆Flood control and safety: The drainage boards quickly drain water, and the modules reduce peak flow, significantly lowering the risk of urban flooding

◆Efficient use of water resources: Rainwater is collected and reused, saving tap water and alleviating water shortages

◆Ecological benefits: Replenishing groundwater, improving soil quality, protecting vegetation, and reducing the heat island effect

◆Modular installation, can be flexibly combined

◆Saves space and reduces overall costs

◆Long service life, simple maintenance

◆Suitable for both new and old urban areas, different terrains, and loads
