Stormwater Storage Modules for Underground Tank Systems

Stormwater storage module system for underground rainwater tanks

Stormwater storage modules create high-void underground tank structures for rainwater harvesting, attenuation, infiltration and controlled reuse. This modular system can be assembled in multiple heights to suit the required storage volume and site geometry.

Leiyuan supplies recycled-plastic modules for subsurface tanks, drainage channels and lightweight void-forming applications. Final selection must be based on the project layout, cover depth, traffic loading, groundwater conditions and the engineer’s hydraulic and structural design. Share these details with us before quotation so the appropriate module configuration can be reviewed.

Technical test data (TRI test)

Leiyuan Tank system can support vehicle loading up to AASHTO HS-20 rating of 32,000lbs loads with safety factors well above AASHTO requirement. Read on and we’ll explain how to handles heavy loads, and why it will work under HS-20 loads for your project.

AASHTO HS-20

10PRINCIPLE:
The first step is to collect the rainwater according to the requirements, and then processing the collected rainwater to achieve compliance with the design using of the standard rainwater harvesting system. At present the sytem is mostly consist of abandoned flow filtration system, storage system and purification system.

FUNCTION:
The function of Leiyuan rainwater collection sytem has two aspects, one is the collection of rainwater and the other one is the reuse of the rainwater. There are five steps, that is collection, transporation, purification, storage and reuse. With these steps we can supply the water in landscape, underground water with the rain water, in this way we can make the full use of the water resource. The advantages of the measures are in many aspects including the reduction of the flood, the reduction pollution of rainwater on the ground, the improvement of the ecological environment. The authorities can design pavement, architecture, pool and street to collect rainwater and reuse it in the landscape.

APPLICATION:
The rain water collection system is mainly used in the storage and reuses of rainwater, such as the drainage along the street, roof garden, parkland, water filtration system, residential area, city road drainage construction, sport field system, the landscape and so on.

ADVANTAGE
-Interconnecting Units                                                    -Light weight and high strength
-Cost effective and eco-friendly                                    -Resistant to acid and alkali
-High capacity and high stability                                  -Strong structural design
-Straightforward installation                                          -Increased Infiltration and Exfiltration
