ABSTRACT

Egypt is an arid country covering an area of approximately 1 million km2, of which its population occupies only 5.5%. The availability of fresh water resources in the country is limited mainly to the Nile River, groundwater from both renewable and non-renewable aquifers, limited rainfalls along the northern coast and flash floods in the Sinai Peninsula. Egypt also practices the use of various types of marginal quality water, such as agricultural drainage water, treated domestic wastewater and desalinated brackish water.
