In Duiven, our team got to work with Joosten Groep on packing infiltration crates. These permeable crates form part of a buffer field, installed under a large car park on an industrial estate.
The crates were lined with over 4,000 m2 of film, divided over three bottom and top covers. The installation of the film creates a watertight buffer field.
Climate changes cause more erratic weather with sometimes heavy rain showers from which large amounts of precipitation fall in a short period of time. This easily overloads sewers. With an infiltration system, rainwater runs via wells to the buffer field, where it is gradually disposed to the sewer after temporary storage. Thus, the crates provide the rainwater with a temporary outlet so that the sewers are spared. An advantage is also that the collected water, if systemically facilitated, becomes usable for e.g. irrigation and washing water.
The infiltration boxes are a fine example of contemporary water management techniques. With Joosten we have already lined infiltration crates in several places in the Netherlands; on roofs, car parks, roof terraces, sports fields and in residential areas, among others.
