The world needs water. Hear what it has to say:

A special word from Fmr. Secretary John F. Kerry, U.S.A. Special Presidential Envoy for Climate Change

“Most people will first experience the impact of climate change through water. Two billion people already lack access to safely managed drinking water, and this problem is only going to get worse due to the climate crisis. The world is changing.”

– Fmr. Secretary John F. Kerry, United States Special Presidential Envoy for Climate Change

Impact in Numbers Created
Through Desalination and
Water Reuse

Climate change is intensifying droughts. Water reuse offers a sustainable solution to meet rising water demands and replenish resources. Around 22,000 desalination plants globally provide clean water to over 300 million people.

What significant developments occurred in the desalination sector?

The global desalination capacity has grown exponentially in recent decades, from 14.5 million cubic meters per day in 2000 to 95 million cubic meters per day in 2019.



Desalination continues to be a pivotal method for securing clean water, particularly in regions experiencing water scarcity. The Middle East and North Africa (MENA) region leads in desalination capacity, with countries like Saudi Arabia and the UAE relying heavily on desalinated water to meet their freshwater needs. In the United States, particularly Florida, California, and Texas, desalination helps supplement water supplies in drought-prone areas. Similarly, Western Australia uses significant desalination plants to combat water scarcity, providing a substantial portion of the region’s drinking water.

As of 2023, the global desalination contracted capacity reached 109.22 million cubic meters per day, facilitated by approximately 22,000 desalination plants worldwide. The capital expenditure (CAPEX) for desalination in 2023 amounted to USD 5,971 million, with a significant increase in new capacity—4.4 million cubic meters per day—contracted in 2022.

Additionally, 356 new desalination plants were awarded between 2022 and 2023, emphasizing the continuous expansion of this vital infrastructure, which now caters to over 300 million individuals globally.

How is water reuse addressing global water demands and what are the key developments in this sector?

Water reuse is emerging as a critical solution to address growing global water demands, particularly in the face of intensifying droughts due to climate change.

In 2023, the global contracted water reuse capacity reached an impressive 259.33 million cubic meters per day, underscoring the scale of this growing practice. In 2022 alone, 12 million cubic meters per day of new water reuse capacity were contracted, with 89 new water reuse plants awarded.

The substantial investments in operational expenditures (OPEX) for water reuse, which amounted to USD 10,759 million in 2023, demonstrate the financial commitment towards ensuring sustainable and dependable water supplies while conserving natural resources.
