Desalination Plants in Algeria: A Strategic Response to Water Scarcity
Desalination plants in Algeria are becoming a central pillar of the country’s strategy to secure long-term drinking water supply. Facing increasing water stress driven by climate change, population growth and limited conventional freshwater resources, Algeria has launched an ambitious national infrastructure program focused on seawater desalination.
This large-scale initiative aims to strengthen national water security while reducing dependence on rainfall and surface water reserves.
A Structured National Plan to Strengthen Water Security
- In recent years, the Algerian government has implemented a structured national plan to significantly increase potable water production from the Mediterranean Sea.
- In its first phase, five large-scale desalination plants are being constructed in the wilayas of El Tarf, Boumerdès, Tipaza, Oran and Béjaïa. Each facility will have a production capacity of 300,000 m³/day, representing a substantial contribution to the national water supply system.
- Additionally, three new major projects have recently been announced in the regions of Tlemcen, Chlef and Mostaganem, further expanding the geographical coverage of desalinated water.
- These developments form part of a broader national program that includes the construction of six additional plants. The objective is to increase total national production capacity to approximately 5.6–5.8 million m³/day by 2030. With this expansion, desalination plants in Algeria are expected to raise their contribution from roughly 18–20% of the country’s drinking water supply to nearly 60% by the end of the decade.
Recent Developments and Capacity Expansion
In March 2025, President Abdelmadjid Tebboune inaugurated the Cap Djinet 2 desalination plant in Boumerdès, with a capacity of 300,000 m³/day, reinforcing water availability in northern Algeria.
According to recent projections, once all ongoing projects are fully operational, desalination plants in Algeria could supply up to 42% of the nation’s total drinking water consumption. This expansion will significantly relieve pressure on traditional water sources and surface reservoirs.
Benefits and Operational Challenges
- Beyond increasing potable water volumes, desalination plants in Algeria are generating positive socioeconomic impacts. These investments create employment opportunities, strengthen technical expertise and enhance resilience against extreme weather events such as prolonged droughts.
- However, large-scale desalination development also presents ongoing challenges. Energy optimization remains a critical factor, as desalination is energy-intensive. Environmental management of brine discharge requires careful planning to protect marine ecosystems. In addition, infrastructure improvements are necessary to efficiently transport desalinated water to inland regions where demand continues to grow.
- Addressing these technical and environmental considerations will be essential to ensuring the long-term sustainability of Algeria’s desalination strategy.
Towards Greater Water Resilience
- The rapid expansion of desalination plants in Algeria positions the country among the Mediterranean nations with the highest seawater desalination capacity. Through sustained investment and coordinated planning, Algeria is moving toward a more diversified and climate-resilient water management model.
- By reducing vulnerability to rainfall variability and strengthening supply reliability, desalination plants in Algeria are set to play a decisive role in meeting the country’s future water demands.
