The AquaReUse concept is creative using multiple ground usage. Through combining land functions, land acquisition costs can be saved and available surface is used efficiently. In this example a water storage is created under a constructed wetland. This is represented in the following image.

Suspended solid from the horticulture waste water is separated from the water which enters the water storage located under the constructed wetland. To filter the smaller floating particles out of the water the flow velocity in the water storage is low, so the particles move to the bottom. The water which remains is now prepared to enter the wetland. Without the removal of the fine particles the efficiency of the constructed wetland would get limited unnecessarily leading to high exploitation costs. Since the water storage has a very high level of self-cleaning, maintenance is not expected to occur often but is possible if required. The height of the water storage (about 1,5 meter) makes it possible for fast and efficient maintenance.

The constructed wetland for the Overbuurtsche Polder will make use of a vertical profile. This means that water is spread on the surface of the wetland. The constructed wetland consist of helophyte plants (like Pragmites) which function like a sand filter, taking up phosphorus. Also biological cleaning occurs in the root zone of the helophyte plants. Under the root zone drainage tubes take out the filtered water thus creating the vertical stream profile. After passing through the wetland the water is biologically rinsed from nutrients and other minerals or metals.
