IV.3. Assessment of environmental sub-vulnerability
IV.3.1.
Water resources
The hydraulic network of the Skikda province is characterized by its dense structure, which can
be attributed to the area's humid climate, slopes, and low permeability terrain. As a result, there
is a greater propensity for runoff rather than infiltration. Skikda's hydraulic potentials consist
of three (03) main types of water resources, namely surface, underground, and spring water.
Understanding the importance resources and how they interact with the local environment is
critical to the sustainable management and utilization of Skikda's water resources. By doing so,
it is possible to ensure the continued availability and accessibility of these resources for the
benefit of the province's communities and economy.
The underground resources: The volume of groundwater resources (from wells and
boreholes) is estimated to be 87,115 Hm3 and is located in the alluvial aquifers of the
rivers in the province, namely El Kébir, Saf-Saf, Guebli, Bibi côtier, Fil-Fila, and the
coastal river of Bougaroun (ANIREF).
The surface resources: The Province benefits from abundant rainfall and a
mountainous terrain that contribute significantly to its hydrology. Despite having a
dense hydrological network with several watersheds, a considerable amount of water is
lost every year due to the lack of adequate mobilization means. The mobilization
infrastructure represented by the Zerdazas, Bekkouche Lakhdar, Oum Toub, and Beni
Zid dams, with a total capacity of 290,667 hm3, along with the two desalination stations,
allowed for the exploitation of 93,177 hm3 of water in 2020. However, the capacity of
the 13 hill reservoirs in the area is only 01.41 hm3, which is insufficient to meet the
increasing water demands of the province (ANIREF).
IV.3.1.1.
Drinking Water Supply
The drinking water supply are:
Network length: 2,082,802 meters;
Connection rate: 94.34%;
Existence of two (02) desalination units;
Demineralization of brackish waters.
