The efficiency of wastewater treatment plants in pollutant removal, although meeting legislation norms, is very often not sufficient, if the pollutants concentrations exceed assimilative capacity of the receiving aquatic ecosystems. Nevertheless, very costly wastewater treatment plant construction and operation has to be carried out by local communities. This project, developed in the 诺儿河Ner River Valley and the Protective Zone of the WWTP(污水处理厂) (see Figure 9.12) focuses on two aspects: the reclamation of a river and its floodplain by means of ecohydrology and phytotechnology and the development of an integrated strategy for restoring cycles of matter and pollutants in the city.
