Rockflow® attenuation and infiltration systems
With Rockflow systems, you can effectively capture and annuate rainwater and gradually infiltrate it into the soil. This prevents urban flooding and contributes to groundwater replenishment, even in urban areas where space is at a premium.
We also offer solutions to temporarily buffer and slowly discharge rainwater. This helps prevent overloading the sewer system during heavy rainfall and reduces the risk of flooding. Delayed drainage can be a solution when infiltration of rainwater is not possible. This may be the case, for example, if the soil is not permeable enough or if the water is of insufficient quality to be allowed to infiltrate. Some or all of the buffered water is then drained to a water system where capacity exists. This is done either with a (delayed) discharge to the waterstream, or with a deep infiltration pile that breaks through the poorly permeable layer. Both with infiltration and delayed discharge, each Rockflow system is designed to be empty and available for the next shower within 24 hours.
