Water Security and Desalination

This page contains abstracts from various reports relating to the topic of Water Security and why Seawater Desalination is an important consideration to achieve global water security. In a recent research study done by a MIT study group Water Security was defined as: 

"....a peoples’ ability to maintain a constant and sufficient supply of safe, clean water
without negatively impacting the people and environment around them...."

The two most pressing concerns for the future of water security are population growth and climate change. The world population is expected to reach 9.6 billion by the year 2050; this growth, combined with ageing Water Treatment Plants, places excessive strain on water supply by governments globally.

Additionally, if nothing is done to correct the unsustainable rate at which aquifers are being depleted, certain aquifers such as the Ogallala, will run dry in as little as 50 years. A lack of water is a human health concern. It is an environmental problem, and it is a political problem. For this reason, water allocation will become a very important issue in the future. Due to climate change and its potential to greatly alter the hydrologic cycle, the future amount of water that will be available for allocation is difficult to predict. The impact of this climate change will be felt especially intensely for developing countries in Central Asia, Africa, and Latin America where the water deficit is projected to increase by as much as 50 percent.
The current global water use is already at 9 trillion m³ a year and this rate is expected to increase annually by approximately 60 billion m³. As a human race we must either use the water we have in a sustainable fashion or else find an alternative water source.



"....Less than 1% of global water is available to humans, 96% is locked up in our oceans ...."

Desalination - an alternative water source - allows people to have access to water that was previously not potable. In most cases this means that coastal cities can use seawater for the supply of potable water to their economies. Saudi Arabia already distributes desalinated seawater over distances in excess 2,500 miles. Desalination and water recycling are both integral components of our “water crisis” solution.

The recent MIT report proposes that desalination be implemented in any ocean bordering a region that does not currently have or is likely not to have sufficient water to meet its demand.

There are presently more than 12,500 desalination plants in operation or in construction worldwide; 60% of these are located in the Middle East and North Africa. This number is set to grow at a rate of approximately 8% year on year until 2030. Desalination combined with Waste Water Treatment is therefore a growing solution provided that it can be done cost effectively and without negatively impacting the environment. 

GrahamTek 16" SuperFlux® is the most cost effective solution to this requirement. Read more about its benefits...

Water Availability

The diagrams below prepared by the MIT research group indicates the current and future water scarcity as well as most applicable locations for Mega Seawater Desalination installations. The intent of Mega Desalination Installations is to provide for future needs not only for the country where the plant is installed but for neighboring  countries where future scarcity may exist.
