Abstract

This study aims to the collect and analysis of statistical and scientific data on water resources in Algeria, particularly in the field of wastewater treatment and reuse. Consequently, many investigations were carried out during the period from October 2014 to February 2015, through the collection of data from the Ministry of Water Resources (MRE), the National Office of Sanitation (ONA), Wastewater Treatment Plants (WWTPs) and Wastewater Treatment Plants (SL). The obtained results show that the water potential, including surface water and groundwater, amounts to 18 billion m3, but they remain very low compared to the growing demand of the population. As for treatment and treatment plants, a remarkable increase has been observed in recent years, in 2015, 200 STEP and 350 pumping stations were registered. The annual volume of wastewater generated by the Algerian population is 927 million m3 / year, of which 700 million m3 / year were treated by ONA and reused by industrial activities (3.1 million m3 / year) and Irrigation (3.4 million m3 / year). In 2014, 108 STEP in operation, of which 60 LS were registered by ONA, and 97 dams for storage of 9.1 billion m3 of water were registered by MRE.
