saltwater into clean drinking waterAccess to clean drinking water is a major issue that continues to affect individuals around the world. Further, an estimated 35% of the entire world population lacks access to “improved sanitation,” for which, access to water (generally speaking) is imperative. The CDC estimates that more than 700 million people live without direct access to an “improved water source,” which includes drinking water, proper household plumbing and wells. As of 2018, new solar-powered technology can now supply individuals with direct access to drinkable water by transforming saltwater into clean drinking water. Innovative technology, it seems, may play a pivotal role in helping to solve yet another global challenge.

GivePower & Solar-Powered Technology

GivePower is an innovative nonprofit behind solar, saltwater farms. Comprised of 20-foot-tall containers and accompanied by solar-powered panels and water pumps, these farms are designed to supply deficient countries with safe, drinkable water. The containers hold 75,000 liters of saltwater, every day. Through clean solar energy, this saltwater is converted into safe drinking water and delivered to surrounding villages. Such technology is relatively new, as saltwater is difficult to convert into freshwater. This is due to its makeup and strong chemical bonds. Therefore, saltwater’s conversion into clean water takes a large amount of energy and money to fund. GivePower, however, can cut the costs by using solar energy to powers its saltwater farms.

In 2018, GivePower built its first saltwater farm in Kiunga, Kenya. An extreme drought had caused Kiunga to experience a major shortage of potable water for cleaning, drinking and cooking. At this time, the city’s only source of water came from saltwater from the Indian Ocean. Individuals living in Kiunga would often contract harmful diseases due to this lack of clean water. GivePower acknowledged this issue and intervened by using its technology to convert the abundance of saltwater into safe, usable water. Not only does the saltwater filtration technology provide more water than typical wells — but it also has a lower impact on the environment through the use of renewable, solar energy.

A Global Impact

This technology has helped to address the water crisis in other countries as well. In many developing countries, it is common to have an abundance of saltwater and a lack of clean water. Due to its high sodium content, individuals consuming large amounts of this saltwater can become very sick. Waterborne diseases such as Vibrio and E. coli can contaminate saltwater, causing severe symptoms and in extreme cases, death. By turning contaminated saltwater into clean drinking water, many communities cannot only increase the availability of clean water but decrease the prevalence of waterborne diseases as well.

Through the innovative technology of GivePower, over 19,000 gallons of safe drinking water has been provided to 25,000 individuals per day within the Kiunga community. Although the company started in Kenya, GivePower has already extended to communities around the world by supplying over 2,000 solar-powered systems to schools, villages and facilities in need of freshwater.

The Path Ahead

As GivePower and other organizations continue to develop technology to turn saltwater into clean drinking water — thousands of individuals around the world can obtain direct access to safe water.
