Water Resources in Algeria

The development of dams and reservoirs

Whereas in 1962 there were only 13 dams for storing 450 million cubic meters of water intended mainly for irrigating the agricultural plains in the west of the country, there are currently in Algeria 84 dams for a total capacity of 8.4 billion cubic meters of water.

Water Transfers A regional transfer program aimed at ensuring greater equity between the territories for access to water has been progressively implemented. These water transfers also meet the objectives of the country‘s food security strategy, which aims to support regions with high agricultural potential. it is consisting of seven inter-basins transfers.

Non conventional water resources

The mobilization of non-conventional water resources has become a priority for the sector to overcome regional deficits in conventional water and to ensure future security in the mobilization of water resources, these unconventional resources include:
– Desalination of seawater,
– Demineralisation of brackish water,
– Reuse of treated urban wastewater.

At the end of 2015, the situation of unconventional water resources mobilization infrastructures in operation is as follows:
– 10 seawater desalination plants with a total capacity of 587.65 hm3 / year
– Population served: 7 111 190 inhabitants
– 21 desalination monoblock plants with a total capacity of 2.9 hm3 / year
– Population served: 247 46 inhab.
– 18 brackish water demineralization station with a total capacity of 33.73 hm3 / year. Population served: 498.16 inhabitants
– Purified waste water for agricultural purposes: 38.77 hm3 / year
– Irrigated area: 6,774 h
