Rainwater infiltration

Rainwater infiltration helps us ensure a vital, green city with a natural water cycle

Protecting the natural water cycle

Also in urban areas, a natural water cycle is essential to combat desiccation. However, urban paving prevents water from being absorbed into the soil. Instead, it flows away via the stormwater sewer to prevent waterlogging during heavy rainfall.

Creating more space for greenery, parks, and natural infiltration is not always possible in urban areas. The available space is sorely needed for other purposes. ROCKWOOL Rainwater Systems offers a solution that takes up no space above ground and creates sufficient space underground for water infiltration. For a vibrant, green city with a natural water cycle.

Keep the water where it belongs

Rainwater infiltrates the soil within 24 hours

With solutions from ROCKWOOL Rainwater Systems, water is returned to the ground. Rainwater is not carried away but is quickly captured on-site in an underground buffer. Within 24 hours, the water gradually infiltrates the soil.

Rockflow factsheet: water absorption

Protecting the local water balance

If rain can infiltrate the ground in built-up areas, more water is available for trees and plants in the immediate vicinity. This promotes biodiversity, shade, and cooling, and keeps the city a pleasant, livable place in hot summers.

Intensive monitoring of a Rockflow system

With smart sensors, the operation of the Rockflow system is monitored to this day. It is evident that the stone wool system - even when partially submerged in groundwater - functions and infiltrates excellently.

Projects

Maasbracht also opts for the Rockflow infiltration system in a residential area

A Rockflow water storage and infiltration system is applied in the municipality of Maasgouw (NL) under residential streets as a rainwater sewer. The municipality had previously successfully installed the Rockflow buffer system under playgrounds and parking lots.
