The Huntington Beach Desalination Facility is a 100% carbon-neutral, cost-effective, environmentally sound solution to provide safe and reliable water.
The proposed seawater desalination facility will provide 50 million gallons of water per day (50 MGD) to Orange County residents while using existing infrastructure to reduce construction costs – a major factor in making water affordable. The 100% carbon-neutral facility will ensure there is sufficient high quality water to meet demands and protect Southern California against the public health, security and economic consequences of water shortages – readily available in times of emergency.
