Vegetated discharge area

Space developed between the wastewater treatment plant and the receiving environment of treated wastewater discharges (it is not part of the wastewater treatment plant). The vegetated discharge areas (VDA) are characterised by the use of plants (mostly aquatic but possibly also terrestrial) and their planting close to the treatment plant, in the space remaining after the building of this plant. The VDA is not a wetland as there is no "long presence of natural water". It is also not a grass strip, specific to the mitigation of non-point source pollution (pesticides, fertilisers, sediments, etc.), especially in agriculture.
