Rainwater collection tank, Ø2300 (6,000–10,000 L)
Rocko Ø2300 - Large-capacity rainwater tank for high water demand.
The Rocko Ø2300 is the largest rainwater tank in the Rocko series and is ideal for applications with high water demand, such as larger residential complexes, commercial properties, or agricultural use.
Despite its large storage capacity, the tank remains space-saving thanks to its vertical design and allows for efficient installation.
Rocko Ø2300 in detail.
The container is made from high-quality polyethylene (PE) in a single piece. This results in a completely waterproof, robust, and durable construction. With a wall thickness of 8–14 mm and stabilizing reinforcing ribs, the tank withstands high soil loads as well as external stresses.
The tank can be used both installed underground and above ground as a freestanding container.
- PE LID WITH ADAPTER (INCLUDED IN THE BASIC PACKAGE)
- The lid, with its gasket and hinged closure, ensures effective watertightness. The PE lid (DN 600) has a load-bearing capacity of up to 200 kg.
- CONNECTION OPTIONS
- ANCHOR HOLES
- They make it easier to secure the tank to a concrete slab when anchoring is required due to a high water table.
- REINFORCING RIBs
- Reinforcing ribs on both sides ensure the tank's stability and provide protection when the water table is high.
- PE RING
- The PE ring allows for easy installation of an additional fuel tank extension, making it easy to adapt to the terrain.
