Hilton Head No. 1 Public Service District's Reverse Osmosis Drinking Water Treatment Facility won national recognition in the American Council of Engineering Companies 2011 Engineering Excellence Awards competition.
The plant, which went on line in 2009 on Jenkins Island across from Windmill Harbour, produces 3 million gallons of drinking water a day -- about half of the utility's average daily demand, district spokesman Pete Nardi.
The plant treats brackish water from the 600-foot-deep Middle Floridan Aquifer. It was needed to replace water supply lost to saltwater intrusion into the 150-foot-deep Upper Floridan Aquifer, Nardi said.
