RoCko 1300 — Cylindrical underground tank from 900 to 2.800 L.
Ø1300 mm diameter. Installed without a crane, without a concrete base.
The RoCko 1300 is a vertical cylindrical tank made from high-density polyethylene (HDPE), with a nominal diameter of Ø1300 mm. Designed for underground or outdoor installation, with no concrete base required. It includes a self-levelling telescopic DN600 access and a lockable cover for loads up to 200 kg. Available in 8 capacities, from 900 to 2.800 L.
Why the RoCko 1300?
The RoCko 1300 is the entry-level solution for rainwater storage, irrigation reserve and service water reserve in single-family homes and smaller properties. The vertical cylindrical profile keeps the excavation area to a minimum and removes the need for a concrete base — a bed of compacted sand is enough.
Weighing between 37 and 92 kg, it can be installed without heavy equipment. The self-levelling Ø600 telescopic cover follows any settlement of the ground and takes pedestrian loads up to 200 kg, with no protective slab needed.
