Tampa Bay Water of Florida, US, has reopened its $160m desalination plant for the first time since 19 April 2010.
The desalination plant is a drought-proof, alternative water supply plant that has the capacity to provide up to 25 million gallons per day of drinking water.
The desalination plant is running on standby and processes nine million gallons of water per day.
The plant produces drinking water through a rigorous pretreatment process before separating fresh water from seawater using reverse osmosis. It can meet 10% of the region's water needs, according to abcactionnews.com.
