Rockflow for water management – natural solutions for sustaining water resilience

The climate is changing: how do we manage extreme rainfall? Not only more rain is falling due to climate change, but rain showers are often more extreme. This means that a lot more water has to be collected and disposed of in a short time. In the countryside this is not usually a problem, but it is more so in the increasingly urbanised environment.

More and more land area is being paved or surfaced, as a result of which water can no longer drain into the soil and must be disposed of via the sewer system. That system is not designed to handle extreme rainfall, resulting in flooded streets and basements and other nuisances for residents. The only way to prevent local flooding is to ensure that water is collected and used, or disposed of more quickly and effectively.

Rockflow is an innovative water management system that buffers the rainfall from extreme showers quickly and effectively for it to be subsequently infiltrated into the soil or discharged to the sewer system.

Water management systems which use Rockflow constitute a sustainable solution to flooding caused by extreme rainfall in urban areas. Rockflow is utilised for water nuisances in streets, in squares and in suburbs, when decoupling areas from the sewer system and when (re)designing water retention areas.


Rockflow benefits

Rockflow is utilised for water nuisance in streets, in squares and in suburbs, when decoupling areas from the sewer system and when (re)designing water retention areas.

  • Rockflow is custom designed
  • Smart water management using Rockflow from Lapinus is always custom designed. In its simplest form, it consists of buried and covered stone wool elements which release buffered water into the soil in a regulated manner. For more complex problems, for example in intensively built-up urban areas, or beneath roads or industrial estates, the system is designed, dimensioned and calculated in conjunction with engineering agencies. In that case, the stone wool elements are connected to a carefully-designed system of pipes, drains, gullies and (stone wool) filtration cassettes.
  • High drainage and buffer capacity
    Rockflow stone wool elements can absorb 95% of their volume in water within a very short time and have a throughput speed of 200 metres per day.
  • No loss of urban space
    The basic material is stone wool, which has all the properties of rock. Vehicles can park on top of the system without the elements becoming deformed or losing any functionality. All urban functions therefore remain unaffected.
  • Self-filtration
    The structure of the stone wool elements filters any contamination from the incoming water, as a result of which the system never becomes clogged. The system continues to infiltrate from the bottom, even without the use of geotextiles. Furthermore, stone wool filtration cassettes can be applied at the entrance into the system or in filtration pits. The elements are easy to replace and are fully recyclable.
  • Custom design
    The stone wool elements are easy to adapt, without loss of functionality during and after installation (without harming quality and performance), so that any pipes or other obstacles in the ground do not represent a hindrance.
  • Sustainable
    Stone wool is a natural material (made from natural rock) which is produced sustainably by ROCKWOOL. Stone wool is 100% recyclable.
