The RORO RB (roll on roll off reed beds) are small, simple and moveable nature based treatment systems for tertiary support.

Each pair is capable of treating up to 2l/s and hydraulically taking up to 6l/s in dilute storm conditions. The beds can be aerated or supplied for solids polishing only and each unit has an integral sludge capture chamber. The units are delivered via hook lift transport and are compact enough for very small sites with a footprint of just 2.3m x 7m per unit.

The RORO RB can be used for works enablement, additional load removal during storm and for proactive management of storm flows on sites that might need additional temporary support.
