Scientists are developing more efficient and environmentally friendly desalination methods by targeting specific molecular bonds.
Brackish Water Desalination in California’s Delta Region
The City of Antioch has pioneered a groundbreaking approach to water management. Its innovative membrane distillation systems in the California Delta represent a major breakthrough. This cutting-edge facility advances low-carbon desalination technology while addressing critical water scarcity challenges.
The desalination plant demonstrates strategic water resource management with impressive capabilities:
- Produces up to 6 million gallons of drinking water daily
- Serves approximately 112,000 residents
- Projected to supply 40% of Antioch’s water by 2025
Funding for this transformative project came through a strategic combination of financial resources:
