Desalination
🚰 Desalinated seawater could ease pressure on the Colorado River
San Diego is negotiating with Arizona and Nevada to sell water from North America's largest desalination plant. The agreement could supply roughly 500,000 people with drinking water annually. San Diego has reduced its water imports from 95 percent to 10 percent over three decades.
🚰 Israel tops up Sea of Galilee with desalinated seawater
Israel has begun channeling desalinated seawater into the Sea of Galilee, marking the first time anywhere in the world that a freshwater lake is topped up with processed seawater. The water level in the lake is expected to rise by approximately 0.5 centimeters per month through the project.
🚰 Energy consumption for desalinating water has decreased by 85 percent
Energy consumption for desalination has decreased from 20 kWh per cubic meter in the 1970s to 2.5-3.5 kWh today. Producing enough drinking water for one person - about 3 liters per day - through desalination would cost only $2.30 for an entire year.
🌊 Desalinates 49,000 liters of water daily, powered by ocean waves
Wave energy propels a new desalination system by Oneka Technologies. The system can filter 49,000 liters of water daily, powered solely by ocean waves.
