The RoCko 1500 is a vertical cylindrical tank in high-density polyethylene (HDPE), with a nominal diameter of Ø1500 mm. Suitable for underground or outdoor installation with no concrete base. It includes a self-levelling telescopic DN600 access and a lockable cover for loads up to 200 kg. Available in 3 capacities, from 2.000 to 2.700 L.
Why the RoCko 1500?
The RoCko 1500 offers more storage while keeping the same simple installation: no crane, no concrete base. The Ø1500 mm diameter gives a good ratio between stored volume and excavation depth, ideal for homes with heavier irrigation use or a need for a service reserve.
The self-levelling Ø600 telescopic cover follows any settlement of the ground and takes pedestrian loads up to 200 kg. The flat bottom sits directly on compacted sand, with no additional building work.
