Underground Rainwater Cistern (8,000 – 16,000 Liters)
Roterra 2100 – Scalable Tank Systems for Every Application.
The new Roterra 2100 series offers modular tank systems for rainwater, potable water (Rodrink), and trafficable applications (Rodrive). A variety of volumes and configurations enables precise adaptation to project requirements—ranging from single-family homes to commercial use.
Roterra 2100 – Efficient Rainwater Utilization with Maximum System Stability
Roterra 2100 is an underground tank system designed for the efficient storage and utilization of rainwater. Engineered for both private and commercial applications, it ensures a reliable supply for garden irrigation, cleaning, and other non-potable water uses—while simultaneously reducing drinking water consumption.
Economic Viability & Efficiency
- 100% Volume Utilization: Inlets in the dome area enable the full utilization of the storage volume.
- Cost-efficient Installation: A narrower excavation pit and reduced backfill requirements lower time and material costs.
- High Connection Capacity: Simple coupling of multiple tanks (up to DN 315) for scalable systems.
- Flexible Connection Configuration: Inlets and outlets can be planned from multiple sides—reducing planning effort.
- Optimized Logistics: Integrated lifting eyes and a forklift-compatible base reduce handling costs on the construction site.
Safety & Structural Analysis
- Superior Structural Stability: High load-bearing capacity and optimized structural integrity for sustained loading in the ground.
- Load-bearing capacity up to 40 tons (Drive): Suitable for traffic areas subject to heavy loads.
- Stable in High Groundwater: Reinforced construction prevents uplift and deformation.
- Oval Tank Geometry: Even load distribution for increased stability.
- Multiple Shaft Solutions: Adaptable to installation depth without structural weakening.
Sustainability & Maintenance
- Durable BPP Construction: Corrosion-free, low-maintenance, and designed for long-term use.
- Underground Installation: Protection against UV radiation and temperature fluctuations extends the service life.
- Modular System: Expandable and adaptable without complete replacement.
- Easy access via access shaft: Maintenance, cleaning, and inspection are effortlessly possible.
- Efficient Rainwater Utilization: Sustainably reduces drinking water consumption.
The Roterra 2100 in Detail
1.Superior Structural Integrity: Enhanced load-bearing capacity and advanced statics ensure the tank remains stable under extreme pressure.
2.Heavy-Duty Traffic Rating: Due to its robust construction, it is traffic-loadable up to 40 tonnes, making it ideal for areas with heavy vehicle traffic.
3.Resilience in Challenging Terrain: The reinforced design provides exceptional resistance to high groundwater levels, preventing deformation or buoyancy issues.
4.100% Volume Utilization: Inlets are positioned on the tank neck, allowing for full use of the internal storage capacity.
5.Extensions: Available with 3 types of risers and covers to accommodate various installation depths and site requirements.
6.Streamlined Logistics: Built-in lifting eyes and a forklift-friendly base ensure simple and safe manipulation during transport and positioning.
7.High-Capacity Interconnectivity: Features large flat surfaces for easy connection of multiple tanks, supporting pipe diameters up to DN 315.
8.Multi-Directional Connections: Inlets and outlets can be configured from multiple sides for maximum plumbing flexibility.
9.Cost-Efficient Installation: Requires a narrower excavation pit and less backfill material, significantly reducing overall installation time and costs.

Advantages of the Roterra 2100
Low transport costs
Thanks to the innovative profile of the Roterra containers, the volume increases in proportion to the surface area, thereby achieving a larger volume per unit of length.
Easy Loading and Unloading
The container can be lifted and moved using lifting straps at the marked points.
Outstanding Structural Stability
The profile of the container is designed to achieve excellent structural stability. Earth loads exert less pressure on the sides of the tank.
Installation
Simple and quick installation
Installing the Roterra is simple due to its shape; it requires a much smaller excavation pit and less backfill material.
Roterra Installation Instructions
FAQ
Underground installation in a prepared excavation pit with a compacted subgrade. Inlet and outlet connections are connected to the existing piping system (DN 110–315). Lifting eyes facilitate placement.
Yes. The height can be flexibly adjusted using telescopic or cylindrical shaft extensions (DN600/DN800).
Yes, thanks to the underground installation, the tank is protected from frost.
Regular inspection of the filter, inlet, and outlet, as well as occasional cleaning of the tank, depending on usage and the degree of contamination.
