Water management for the urban environment

Nederlands / Dansk

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 nuisance for residents. The only way to prevent this local flooding is to ensure that water is collected and used or disposed of more quickly and effectively.

This is exactly what Rockflow from Lapinus is designed to do.


This is how rockflow works

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.

Stone wool can also be used for watermanagement in sports, landscaping and water treatment

The Rockflow stone wool elements have a spare volume of

The Rockflow system is used underneath
roads, streets, squares, car parks, industrial estates, water retention areas
or other locations where water nuisance can occur.

The system can be configured in such a way that the volume is fully available again within
24 hours

Water management with Rockflow

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.

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.

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. 

The stone wool elements are easy to adapt, without loss of functionality during and after installation (without harming quality and performance), so any pipes or other obstacles in the ground do not represent a hindrance.

Stone wool is a natural material (made from natural rock) which is produced sustainably by ROCKWOOL. Stone wool is 100% recyclable.
