Rainwater pits for rainwater management
The right rainwater pit is essential for sustainable rainwater management in construction and infrastructure projects. The assortment includes both concrete rainwater pits and lightweight PE tanks, suitable for various storage capacities and installation situations.
Concrete offers maximum stability and durability, while PE tanks are characterized by their light weight and quick installation.
Concrete or PE rainwater tanks: the most important differences
The rainwater tank market consists mainly of concrete and plastic (PE) solutions. Concrete is known for its robustness and high stability, while polyethylene (PE) rainwater tanks offer specific benefits in situations where flexibility and ease of installation are crucial.
PE tanks are distinguished by:
- lightweight: easy to transport and install, even on hard-to-reach sites
- flexible shape and dimensions: suitable for tight spaces or specific installation situations
- corrosion-resistant and durable: impervious to rust and groundwater influences
- easy maintenance: smooth inner walls ensure quick cleaning and less deposit

FAQ
1. When do you choose a PE rainwater tank instead of a concrete rainwater tank?
A PE rainwater pit is often the best choice when a construction site is difficult to access, when quick installation is important, or when soil conditions impose specific requirements. Thanks to their low weight and the various available shapes, PE tanks are easier to transport and install than traditional concrete rainwater pits.
2. Which rainwater tank is suitable for a high groundwater level?
In high groundwater conditions, specially designed PE rainwater tanks with reinforced rib structures are a suitable solution. This construction distributes the pressure of the groundwater across the entire tank wall, which increases structural stability and supports the lifespan of the installation.
3. Which rainwater tanks are suitable for renovation projects?
During renovations, compact or modular PE rainwater tanks are often the most practical solution. Some models can be brought in through restricted passages or narrow access roads, allowing existing homes and inner-city projects to also be equipped with rainwater harvesting.
4. What solutions exist for large-scale rainwater storage?
For utility construction, apartment projects, industrial sites and collective facilities, larger PE storage tanks, HDPE buffer tanks and underground storage systems are available. These solutions can be tailored to the required storage capacity and the project's water management plan
