The Development Prospect Of Rainwater Harvesting Module

With the global water shortage and 40% of the world's population facing water shortage, rainwater harvesting has become a rigid demand for urban waterlogging and the demand for green infrastructure has increased, and the water storage module (rainwater harvesting, sponge city core components) has ushered in a period of rapid development. The expansion of sponge cities in China has added more than 30 cities in 2024, and the "Technical Specifications for Urban Rainwater Storage Facilities" mandatory storage systems for new projects. The European Union's "Green Infrastructure" plan calls for rainwater reuse rates of more than 80% by 2030. Rainwater reuse reduces the energy consumption of municipal water supplies. Water storage module is the core component of sponge city, intelligent management, module structure innovation.

The functions of rainwater harvesting module:

Alleviate urban waterlogging and replenish groundwater

Water conservation and energy saving

Industrial water circulation, anti-pollution and seepage

Ensure subgrade stability and emergency drainage

Drought-resistant irrigation, ecological water replenishment

Peak flow regulation, disaster prevention buffer

Rainwater harvesting module application:

Sponge city construction

Road rainwater collection, parks/plazas water storage:Rainwater modules are buried under sidewalks or green belts to collect road runoff.

The top of the module is covered with soil to plant waterlogging tolerant plants forming an ecological landscape.

Water saving and consumption reduction: roof rainwater recycling, underground garage drainage.

Industrial water circulation, anti-pollution and seepage.

Highway drainage: Water storage modules are embedded in service areas or slopes to collect rainwater for green irrigation.

Waterlogging prevention of airport runways.

Therefore, the rainwater collection module is widely used and has a good development prospect
