Rainwater tank ROCKO 1300

water storageundergroundfree-standing

Overview
The Rocko Ø1300 rainwater tank is a compact vertical solution for collecting and storing rainwater on small to medium properties. Its space-saving one-piece polyethylene (PE) construction provides 100% watertightness while the 8–14 mm wall thickness ensures stability against soil loads and external influences.

Details
The tank is designed primarily for underground installation but can be used above ground as a freestanding unit. Its vertical shape simplifies handling and installation and often allows assembly without heavy machinery. An integrated DN 600 inspection opening (300 mm height) offers easy access and can be adapted to site conditions. Extensions enable adapting tank height to terrain.

Included / Basic package

• PE lid with adapter (DN 600), gasket and hinged closure for watertightness
• PE lid load capacity up to 200 kg
• Integrated DN 600 inspection opening (300 mm height)

Product features

• One-piece rotationally moulded polyethylene (PE) construction — 100% watertight
• Wall thickness: 8–14 mm for high structural stability
• Reinforcing ribs on both sides for stability and protection against buoyancy when groundwater is high
• Multiple connection options and integrated extension possibilities
• PE ring for simple installation of additional extension segments
• Mounting holes available for anchoring to a concrete slab if required
• Suitable for underground installation and as an above-ground freestanding tank
