Case Study: Our 100,000 m³/day solar-integrated desalination plant in Mauritania delivers water at $1.2 per ton – 20% cheaper than groundwater – boosting fish processing capacity to 80% while cutting CO₂ emissions.
Case Study: How Mauritania Shattered the Desalination Cost Paradigm
Focus Keywords: low cost desalination, solar powered RO plant, desalination for industrial growth, green desalination Africa
Executive Summary: Redefining What’s Possible in Arid Regions
In arid Northwest Africa, where high-cost desalination was considered an unavoidable barrier to economic development, Mauritania needed a breakthrough. We delivered a 100,000 m³/day solar-RO plant that not only secured water for the capital but became an economic catalyst, delivering water at a disruptive $1.2 per cubic meter – 20% cheaper than local groundwater – while boosting industrial output and reducing carbon emissions.
The Challenge: When Water Costs Stifle National Potential
Mauritania faced a critical dilemma common to many arid nations:
Economic Stagnation: Assumed high desalination costs prevented the development of key industries, particularly the vital fishing sector
Resource Limitations: Existing water sources couldn’t support both municipal needs and industrial expansion
The True Objective: The solution needed to be economically transformative – delivering not just water, but economic opportunity
Our Integrated Solution: Where Green Technology Meets Economic Sense
We reimagined desalination economics by making solar power integration a core design principle rather than an optional add-on:
Hybrid Power Architecture: Seamlessly integrated solar power to cover 30% of the plant’s energy load
High-Efficiency Reverse Osmosis: Paired with advanced RO membranes to maximize output per unit of energy
Intelligent Operation: Smart controls optimized energy use between solar and grid power
The Result: A fundamental restructuring of desalination’s cost equation
The Disruptive Outcomes: Measurable Impact Across Three Dimensions
Economic Transformation
💸 Record-Breaking Water Cost: Achieved production at $1.2 per cubic meter
📉 Cost Advantage: 20% less expensive than local groundwater, shattering previous cost assumptions
