Tetra Tech's goal is to design, engineer, construct, and start up the Huntington Beach Water Desalination Facility for Poseidon.The facility will have the capacity to provide 50 million gallons of high-quality drinking water per day. The facility will produce enough water to meet approximately 7% of Orange County’s water needs. On-site storage will also provide a guaranteed supply of safe, reliable drinking water to Orange County in times of emergency, reduce the risk of water shortages, and reduce dependence on imported water.
