8.000 – 16.000 Liter
Roterra 2300 - Rainwater tank for larger projects
The Roterra 2300 is a high-performance rainwater collector for underground installation and is ideally suited for private, commercial, and agricultural applications. It is available in sizes of 8,000, 10,000, 12,000, and 16,000 liters, thereby reliably covering medium to larger water demands.
Hergestellt aus umweltfreundlichem Polyethylen (PE) überzeugt der Tank durch hohe Stabilität, Korrosionsbeständigkeit und eine lange Lebensdauer im Erdreich. Die Konstruktion ist speziell für die Erdverlegung ausgelegt und bietet eine sichere, langlebige Lösung zur Regenwasserspeicherung.
Der Zugang zum Tank erfolgt über einen klappbaren, flachen und begehbaren Deckel mit Ø 600 mm, der auf einem Teleskopauszug montiert ist. Dieser ermöglicht eine einfache und präzise Anpassung an die jeweilige Geländeoberkante. Eine integrierte Dichtung sorgt für zuverlässige Wasserdichtheit.
Die Zulaufanschlüsse werden projektspezifisch ausgeführt – entweder als Gewindeanschlüsse (½″, ¾″, 1″, 2″) für die Wasserverteilung oder für PVC-Rohre von DN 32 bis DN 400 bei Freispiegelüberläufen. Dadurch lässt sich der Roterra 2300 flexibel in unterschiedlichste Entwässerungs- und Nutzungskonzepte integrieren.
Der Roterra 2300 kombiniert großzügiges Speichervolumen, langlebiges Material und flexible Anschlussmöglichkeiten – eine wirtschaftliche und zukunftssichere Lösung für effiziente Regenwassernutzung im Erdreich.

Advantages of the Roterra
Low transport costs
Due to the innovative profile of the Roterra containers, the volume increases in relation to the surface area, so that a larger volume per unit of length is achieved. A Roterra container 2450 with a volume of 65,000 l can be transported on a truck.
Easy loading and unloading
The tank can be lifted and repositioned at marked points using lifting straps.
Great statics
The profile of the tank is designed in such a way that excellent structural stability is achieved. The soil loads can exert less pressure on the sides of the tank.
Installation
Simple and fast installation
The installation of the Roterra is simple due to its shape; it requires a much smaller excavation pit and less fill material.
