water storageundergroundclosed

Overview
The new generation of Roterra 2450 water tanks offers easy, cost-effective installation, maintenance and cleaning. Rainwater collectors reduce mains water consumption and allow savings on utility costs. Roterra 2450 systems are also suitable for properties without existing plumbing.

Key benefits

• Elliptical profile increases usable volume relative to footprint.
• Reduced transport costs (large volumes can be transported on semi-trailers).
• Loading and unloading simplified thanks to marked lifting points.
• Easier and less expensive installation: shorter excavation length and lower backfill material requirements.
• Excellent structural performance: elliptical shape distributes vertical soil and groundwater pressures optimally.
• Polyethylene recyclable at end of life.

Technical elements and features (extract)

• DN 600 cover with seal and hinged opening (load capacity up to 200 kg for the DN 600 version).
• Optional DN 800 cover with additional adapter (adjustable riser height according to terrain).
• Inlet and outlet: multiple possible connection positions on the tank.
• Flat base for quick installation and reduced backfill.
• Connection options on sides and ends depending on configuration.
