Beni Messous WasteWater Treatment Plant, Algeria
Sustainable Water Reuse for a Greener, Resilient Algiers
WABAG developed the Beni Messous Wastewater Treatment Plant near Algiers, significantly enhancing wastewater management for a population of 250,000. By integrating mechanical and biological treatments with tertiary filtration and disinfection, the facility ensures high-quality purification and enables the safe reuse of treated wastewater for urban irrigation. With an expanded second treatment line and a combined capacity of 5,500 m³/h, the project strengthens water security, reduces dependence on freshwater sources, and supports a more sustainable urban ecosystem.
EPC Delivery of an Advanced Wastewater Treatment Plant
The project was executed on a turnkey (EPC) basis, covering design, engineering, equipment supply, installation, and commissioning. WABAG’s end-to-end delivery ensured optimized performance, modern treatment systems, and long-term operational reliability for the region’s wastewater infrastructure.
Integrated Mechanical and Biological Treatment Processes
The treatment scheme includes:
- Mechanical pre-treatment
- Primary sedimentation
- Activated sludge process
- Aerobic sludge treatment
- Sludge dewatering
- Odour treatment (biofilter)
These processes ensure stable biological performance, consistent pollutant removal, and compliance with Algerian environmental norms.
Tertiary Treatment for High-Quality Recycled Water
To achieve safe reuse standards, the plant employs advanced tertiary polishing, including:
- Sand filtration
- UV disinfection
This ensures treated wastewater is safe for urban greenery, public spaces, and non-potable applications.
Urban Irrigation and Water Reuse for Environmental Sustainability
The project enables the reuse of treated wastewater for irrigation in Algiers’ public landscapes. This reduces stress on freshwater aquifers, supports green cover, and improves climate resilience. By promoting circular water practices, the facility advances urban sustainability and responsible water resource management in the region.
