Madinat Salman WasteWater Treatment Plant, Bahrain
Water Recycling and Reuse Plant Supporting Sustainable Water Security in Bahrain
The Madinat Salman Water Reclamation Plant is a flagship water recycling and reuse facility built to advance Bahrain’s national vision for sustainable water management. Designed and executed on reclaimed land to serve the fast-growing new city of Madinat Salman, the plant treats municipal wastewater to high-quality standards, supporting large-scale reuse for irrigation and landscaping.
High-Performance Water Reclamation Plant for Community Irrigation
The facility integrates a modern water reclamation process that combines mechanical, biological, and tertiary treatment stages to ensure safe and reliable treated wastewater reuse. With a dedicated 21-meter-deep terminal lift pumping station and advanced sludge processing systems, the plant supports the water needs of over 100,000 residents while protecting the city’s sensitive groundwater zones.
Treated Wastewater Reuse Strengthening Circular Water Economy
A key feature of this water recycling and reuse plant is its emphasis on circularity. The reclaimed water produced is channelled for community irrigation across all 13 islands of Madinat Salman, significantly reducing dependency on freshwater resources. In addition, the facility generates packaged, fertilizer-grade biosolids through its comprehensive sludge treatment system—demonstrating a model for sustainable resource recovery.
Reliable O&M Excellence Reinforcing Long-Term Water Sustainability
Since commissioning, WABAG has continuously operated the water reclamation plant, meeting stringent performance benchmarks and ensuring uninterrupted reuse supply for the region. Recognising WABAG’s operational reliability, the Ministry of Works extended the O&M contract for an additional five years, further strengthening Bahrain’s long-term wastewater reuse strategy.
Comprehensive DBO Scope for a Future-Ready Water Recycling and Reuse Plant
The scope included full Design, Build, and Operate responsibilities:
- Engineering, equipment supply, installation, and commissioning
- Terminal pumping station construction
- Training of client personnel
- Extended O&M for long-term lifecycle performance

Advanced Treatment Process Ensuring Safe and High-Quality Reuse
The integrated treatment scheme includes:
- Inlet Chamber & Terminal Lift Pumping Station
- Mechanical Pre-Treatment: Screening, aerated grit chambers
- Biological Treatment: Activated sludge process with MLE configuration
- Tertiary Treatment: Disc filtration, chlorination, TSE storage
- Sludge Treatment: Thickening, aerobic stabilization, thermal drying, pelletization (25 kg bags)
- Odour Control & SCADA: Fully automated plant with monitoring
These combined processes ensure the reclaimed water meets Bahrain’s quality norms for safe reuse.
 Sustainable Reuse and Circularity Benefits
- Treated effluent reused for community irrigation
- Fertilizer-grade pellets produced from treated sludge
- Protection of local freshwater aquifers through reduced abstraction
Environmental and Social Impact for Bahrain
This water recycling and reuse plant has significantly advanced Bahrain’s goals for sustainable water management by:
- Providing a reliable non-potable water source across all islands of Madinat Salman
- Reducing freshwater demand and protecting aquifers
- Creating sustainable fertilizer products for agricultural use
- Supporting climate-resilient urban development through long-term water reuse
 A Benchmark Among Leading Water Recycling Companies Globally
With its integrated reuse, sludge-to-fertilizer, and long-term O&M excellence, the Madinat Salman Water Reclamation Plant reinforces WABAG’s position among leading water recycling companies globally—delivering sustainable, high-performance solutions for municipal wastewater reuse.
