Rainwater tank ROCKO Ø1500

water storageundergroundabove-ground

Short description
The Rocko Ø1500 is a vertical rainwater tank suitable for residential and commercial applications. Its compact footprint provides significant storage capacity while minimising excavation and site footprint. Manufactured in a single moulded piece of polyethylene (PE), the tank is fully watertight with a wall thickness of 8–14 mm.

Materials & Construction

• Material: polyethylene (PE), single-piece moulding, 100% recyclable
• 100% watertight single-piece construction
• Wall thickness: 8–14 mm
• Reinforcing ribs for structural stability and protection in high groundwater conditions
• Anchor holes for fixing to a concrete slab when required
• Integrated extension ring for height adaptation to site conditions
• DN 600 dome/manhole integrated; dome can be shortened to match terrain
• PE lid with gasket and hinged closure (DN 600) included; lid load-bearing capacity up to 200 kg

Installation & Access

• Designed primarily for underground installation; can also be installed above ground where suitable
• Vertical shape reduces excavation volume and backfill material
• Facilitates transport and handling on site; often installable without heavy machinery
• DN 600 manhole ensures easy maintenance access
• Height and access adjustable via extension ring and dome shortener
