This is important in semi-arid and arid areas where the few wet natural habitats of the birds have been invaded by urban, tourism or agriculture development. Wastewater reservoirs as an emergent wastewater treatment technology . The reservoirs are a must in almost any wastewater reuse project, where there is always a need for regulation between the almost constant sewage flow and the irregular water demand for irrigation. Meanwhile, the effluents will reach excellent quality due to long residence time within the reservoirs during the summer months. Wastewater of high quality will be released from the reservoirs to the river when river-flow is at maximum, thus obtaining maximum dilution and minimum negative ecological impact.
Wastewater is stored when river-flow is at maximum.
Wastewater of very high quality is then released from the reservoirs to the rivers during the dry period as a substitute for freshwater, in order to avoid total drying and ecosystem destruction in rivers whose dry-season freshwater sources have been derived for other purposes. Stabilization reservoirs are able to remove most of them. This book . The authors are the researchers, agronomists, engineers, biologists, etc., who actively worked on the specific subject of each chapter. A series of case studies which summarize some of the most interesting field works performed on these systems.
