## Water: a growing global challenge
The world faces an unprecedented water crisis with multiple interconnected challenges. Global water demand is projected to**increase by more than 50% by 2050**, while half of the world's population already faces water scarcity. Climate change is intensifying these challenges through more frequent devastating weather events, with drought alone costing $300 billion annually. Water quality is also deteriorating, with over **50% of European rivers exceeding safety standards for pollutants. .**
The economic impact is severe - water-scarce regions could lose 6% of GDP by 2050. This complex situation demands urgent, innovative, and affordable solutions to secure our water future.1 More than ever, the need for a key actor in **sustainable solutions including**[ **sustainable desalination**](/en/solutions/seawater-desalination) **is needed.**
## Veolia leads the way toward sustainable desalination worldwide
Faced with the initial challenges of desalination - high production costs, high energy intensity and impact on biodiversity - innovation has transformed this technology into a particularly relevant solution: **more reliable, more accessible and more sustainable, with energy consumption reduced by a factor of five and minimized environmental impact.** This evolution addresses climate change challenges and offers a promising alternative for the 80% of the world's population living near seas, especially when traditional solutions prove insufficient.
With **more than 50 years of experience in developing sustainable desalination projects** around the world, and references spanning over 2,300 plants, Veolia leads the way to help its clients addressing water scarcity challenges every single day. Having built **18% of the world's installed desalination capacity, including 19% in the Middle East2**, the Group provides innovative and [sustainable desalination solutions](/en/solutions/seawater-desalination) to address growing water scarcity challenges worldwide.
### WHY CHOOSE DESALINATION?
Desalination stands as a vital solution in the fight against water scarcity, particularly for coastal regions. Its effectiveness is proven in countries like Oman, where it provides 86% of potable water. As part of an integrated water management approach, **desalination complements other strategies such as consumption reduction, infrastructure improvement, and** [**treated wastewater reuse**](/en/solutions/wastewater-reuse)**.** While some regions like France (<1%) and the US (4%) currently use minimal desalination, its adoption is growing worldwide as an essential tool for ensuring sustainable water supply.3
## Veolia’s ambitions in sustainable desalination
Veolia's 2030 desalination strategy demonstrates the company's commitment to maintaining **its position as a global leader in water desalination.** With a clear focus on growth, Veolia aims to maintain its significant 18% market share in global desalination capacity while simultaneously doubling its Operations & Maintenance capacity. This ambitious strategy reflects both Veolia's long-term vision and its dedication to addressing growing global water scarcity challenges through sustainable desalination solutions.

## Veolia: sustainable desalination projects
#### Australia : Sydney desalination plant
Veolia has been operating Sydney's major desalination facility since **2009 through a 20-year operation and maintenance contract.**
This state-of-the-art plant produces 250,000 m³ of potable water daily using Reverse Osmosis technology,**providing 15% of Sydney's total water supply.**
This facility demonstrates Veolia's long-term commitment and expertise in delivering essential water infrastructure for major metropolitan areas.
#### Europe: Palma De Mallorca and Cornwall desalination plants
Veolia operates significant desalination facilities across Europe, with notable installations in Spain and the United Kingdom.
In the Balearic Islands, the Bahia de Palma facility, Veolia's largest in Spain, has been producing **64,800 m³ of drinking water daily since 1999 through nine reverse osmosis lines**, serving as a vital water supply for the region.
In Cornwall, England, Veolia manages an unexpected but crucial seawater desalination plant, generating **20,000 m³ of** **water daily, serving both industrial needs and 300,000 residents** in an increasingly water-stressed area.
#### Oman: Sur desalination plant
Veolia operates two cutting-edge desalination plants in Sur, Oman, producing produisant **131,000 m³ of potable water daily through 2036.**
These facilities showcase Veolia's advanced **Reverse Osmosis technologies**, featuring smart membranes, Barrel pilot systems, and the world's largest beachwell supply system.
As a pioneer in sustainable desalination, the site stands out as the region's largest solar-powered desalination plant, operating on **100% solar energy during daylight hours.**
## FOCUS | Veolia, solidly anchored in the Middle-East
#### Revenue expected to double by2030
#### 86% of drinking water in the Sultanate of Oman comes from seawater desalination
#### 15 million people supplied with desalinated water by Veolia in the Middle East

### The Barrel™ : at the heart of a new sustainable, affordable and scalable offer
The Sur desalination plant in the Sultanate of Oman is home to a major technological innovation developed by Veolia: the Barrel™. A cylindrical vessel 10 meters long and 2 meters in diameter houses membranes and optimizes the reverse osmosis water filtration process. Capable of producing 5,000 cubic meters of water a day, the BarrelTM uses digital technologies to track membrane performance. This disruptive technology delivers significant advantages – **a 3% to 5% reduction in the average cost of a desalination plant, energy savings of 1.5%, and a 25% smaller footprint than conventional systems** – and gives Veolia a genuine competitive advantage in the booming desalination market. The Barrel™ marks a major step forward in terms of optimizing the performance and lowering the cost of desalination plants.
