Drainage of Rain Water

EXPO-NET BIO-BLOK® drywell – The professional solution to local drainage of rain water

Rain water is a valuable resource. As a contractor, sewage contractor or advisory engineer you can help preserve this irreplaceable resource.

With relatively simple methods using the BIO-BLOK® rainwater drywell, the rain water can be channelled back into a natural water cycle and thus the load on sewage systems and purification plants can be reduced.

The principle is called local drainage of water. It simply consists of rain water from an urban area being channelled to a so-called drywell which can hold the amount of rainfall and continuously release it for seepage into the groundwater.
